HUBER+SUHNER Light weight and high reliability
The light weight, high performance microwave cable assembly
The SUCOFLEX 300 light weight, low-loss flexible microwave cable assemblies are highend products designed to meet the stringent needs of space flights systems (e.g. satellites)
and aerospace systems (aircraft, helicopters, missiles), which are subjected to extremely
severe operating conditions.
The 300 series offers a consistently outstanding mechanical and electrical performance,
stability and reliability up to 18 GHz with double shielding for improved screening attenuation. The added feature of this SUCOFLEX type is a weight reduction of up to 40 % compared to our conventional products.
The flexible bend-to-the-end high performance cable assembly
The minibend product family is designed for use in low profile, internal, point-to-point
interconnections between RF modules within communications systems. Four product lines
offer true flexible replacements to .047, .086, and .141 diameter semi-rigid coaxial cable
solutions. The patented minibend connector attachment method does not require solder for
the outer conductor attachment. This provide the unique advantage of a fully flexible cable
immediately behind the connector providing bend-to-the-end low profile solutions for
congested cable installations. The assemblies meet all NASA and ESA requirements for
low-outgassing materials.
Smallest threaded open source connector
The unique and innovative combination of a MIL-STD-348 SMPM female interface connector together with a retractable threaded nut provides an integrated solution offering
unprecedented electrical and mechanical performance. The SMPM-T handles high density
requirements with a connector centreline-to-centreline spacing of just 5 mm (0.20 inch)
while offering unmatched electrical stability at frequencies up to 65 GHz in even the harshest operating environments
Connectors
The connector product portfolio certified for use in space is designed for the most unique
and difficult customer applications. The array of connector interfaces, panel mount geometries, printed circuit board (PCB) launch profiles, and customised design solutions is growing dynamically in response to the high technical demands of our customers. The materials
selection of our connectors meets or exceeds the requirements of MIL-PRF-39012. Panel
mount and PCB launch connectors are designed taking into account the unique design
constraints of each customer application to provide optimised electrical and mechanical
performance in any mounting style or launch topography. Our connector space flight heritage spans both North American and European satellite programmes.
Phase shifters
The phase shifter product family is designed for use in electronic systems where precision
adjustment and tuning of transmission line electrical lengths are required. The phase shifter,
or line trimmer, is designed to allow precise in-line phase change while maintaining constant VSWR and Insertion Loss performance values. The construction of the phase shifters
incorporates fine gauge threads for precise tuning accuracy at a resolution of less than 0.1
degrees. A variety of interfaces and phase adjustment ranges are available with operation
up to 26 GHz. These passive devices have proven successful in aerospace and satellite
programmes with flight heritage in both North America and Europe.

Ground testing
HUBER + SUHNER emerged in space as a partner for passive microwave components that can be used for satellite
testing in clean rooms as well as in thermal-vacuum environment. These components support the satellite during the entire
trial period prior to launch. The comprehensive product range is optimally matched to the needs of the space customers.
From the comprehensive range of TVAC components in the vacuum chamber of the hermetic adaptors to the test assemblies in the clean room the procurement process is simplified by offering «one stop shopping». This is true both for low
power and high power applications.
The power handling capabiliy of all assemblies is determined using simulations which are verified with real power tests
and therefore performance predictions are accurate.
Our thermal vacuum assemblies pass thermal cycling qualification to guarantie stable interface dimensions. On request,
our cable assemblies can be produced in clean room environment and stabilisation thermal cycling can be applied.

HUBER+SUHNER Light weight and high reliability
High performance assemblies
The SUCOFLEX microwave assembly family has been specifically developed for high performance, Test+Measurement technology applications, and anywhere the best insertion
loss, high phase stability versus temperature, excellent return loss and mechanical stability
are of the utmost importance.
Today's advanced radio frequency systems enable critical applications in space and must
comply with the highest demands, so it is essential that the interconnection components that
they rely on meet the highest standards as well. The SUCOFLEX family meets these challenges and provides the opportunity to design with the highest performance microwave cable
in its class.
Passive components
The comprehensive range of high-quality radio frequency components is based around the
varying needs of Test+Measurement. The components are compatible with one another
and have stable characteristics of a very high quality. This high quality level results from
many years of experience in the development and production of radio frequency components.
TVAC assemblies
Whole satellites or space components are tested in thermal vacuum chambers under the
conditions found in outer space. They are exposed to vacuum and extreme temperature
variations. The devices under test are connected to the measuring instruments outside the
chamber using special RF assemblies.
One important requirement is that the assemblies used within the vacuum chamber must
meet the ECSS-Q-ST-70-02 C and NASA reference publication 1124 outgassing standard
to prevent contamination of the chamber or equipment by solvents evaporating from certain
materials.
To prevent the assemblies becoming stressed and to ensure an extended service life,
HUBER+SUHNER TVAC connectors contain venting holes that allow an unimpeded flow of
air into and out of the components during the pressurisation/depressurisation cycles.
Hermetic adaptors
HUBER+SUHNER offers a wide array of hermetic feed-thru style adaptors that offer both
in-series and between series interface solutions for TVAC testing applications. The hermeticity is provided by a glass fired seal within the adaptor body. The glass material is selected to provide the best electrical performance while also matching the coefficient of
thermal expansion of the surrounding body and contact as closely as possible to prevent
any loss of hermeticity. All of the hermetic adaptors are 100% tested for hermeticity in
accordance with ASTM E-498, MIL-STD-202, and MIL-STD-883.

The 32071 cable is optimised for extremely high power handling applications. The dielectric core construction is comprised
of concentric layers of expanded PTFE tape to provide uncompromising mechanical strength and durability along with a high
velocity of propagation. These features minimise the attenuation and improve the thermal conductivity of the dielectric core.
The result is lower power dissipation and heat generation with
improved heat transfer capacity. The cable assemblies are
ideal solutions for high power TVAC testing applications.

Thermal vacuum hermetic sealed adaptors
HUBER+SUHNER offers a wide array of hermetic feed-thru style adaptors that offer both in-series and between series interface
solutions for TVAC testing applications. The hermeticity is provided through a glass-fired seal within the adaptor body. The glass
material is selected to provide the best electrical performance while also matching the coefficient of thermal expansion of the
surrounding body and contact as closely as possible to prevent any loss of hermeticity. All of the hermetic adaptors are 100%
tested for hermeticity in accordance with ASTM E-498, MIL-STD-202, and MIL-STD-883. The guaranteed leakage rate is less than
1 X 10E-8 ccm/second of helium under a pressure differential of 15 psig (1 bar).

Technology driver
In order to be able to provide passive RF or microwave components for space applications with product features according to our customers’ requirements, HUBER+SUHNER closely monitors the technology drivers which constantly push the
limits of product performance figures. As in many other industries, some widely-known performance drivers are: ever
increasing bandwidth, increase in operating frequency and size/miniaturisation. Furthermore, all aspects related to signal
transmission characteristics are also important due to the cascading and combing of carrier systems. These features
include, for example, passive intermodulation, corona, multipaction and return loss levels within the RF sub-systems. Not
surprisingly, weight plays a major role in all space flight applications and special attention is paid to the overall product
weight during the product development process. In parallel to these design efforts, the passive components are optimised
for transmission of RF power.
Instead of focusing solely on designs for even higher power levels, HUBER+SUHNER is committed to keeping or reducing
the current component size whilst not compromising on acceptable power levels. The most critical product feature,
however, is stability versus change in environmental conditions. This includes temperature changes and cycling, mechanical manipulation (vibration, shock, bending, etc.) and is evaluated through a rigorous in-house testing and qualification
programme. All these measures ensure that HUBER+SUHNER is able to provide a high performance and high reliability
passive component to our customers which meets the outstanding technical requirements of todays’ space products.

Up screening
Up screening is the process through which standard components and processes are inspected and tested to spaceflight level requirements to qualify them for use in space applications. This process includes serialising each component within the manufacturing lot and
subjecting the components to the screening requirements of MIL, ESA, and/or NASA specifications along with any tailored customer requirements. The components must pass all of
the test profiles successfully to be considered up screened. During the screening testing,
additional variables and attributes data is recorded, verifying the electrical and mechanical performance of the components to provide evidence of the successful completion of the
entire screening test process. This data is then collated and supplied to the customer along
with the components in an End Item Data Package (EIDP). If the use of single component
manufacturing lots, is required by the customer this additional screening will be performed
to select the appropriate manufacturing lot that will qualify for up
screening.
Please contact HUBER+SUHNER to discuss your specific needs in selected up screened
hardware solutions that can offer a significant cost and lead-time reduction for your space
or vacuum application.

Special applications
The first two Galileo satellites have been orbiting the earth since October 2011. They were
joined by a second pair in October 2012. These four satellites are being used to test the
infrastructure’s functional capacity, both in space and on the ground. A further 14 satellites
will then enter orbit during 2013 and 2014, featuring radio frequency assemblies from
HUBER+SUHNER for connecting the navigation antenna to the satellite. As the radio frequency power was increased during Galileo’s development, the various components involved also needed to be modified to meet the new requirements. HUBER+SUHNER is providing cable assemblies with MMBX type connectors that are capable of transferring the
higher power level required. These connectors feature a special design with excellent
properties that better shields the inner and outer conductors from each other using overlapping insulators in the connector and on the transition to the cable.
This prevents resonance, which could cause the emission of undesirable electrons to snowball and impair the transfer (multipactor effect). HUBER+SUHNER has already delivered
around 4‘500 components to its direct customer for use in 18 satellites. To ensure that the
individual parts meet the strict ESA requirements for use in space, they are assembled in a
special cleanroom at HUBER+SUHNER in Herisau, Switzerland.
HUBER+SUHNER has demonstrated its expertise to the ESA and the direct customer alike
and is regularly called upon to help solve problems. An excellent basis for navigating the
road ahead together.

High power - multicarrier application
Under the auspices of the European Space Agency (ESA), a European consortium comprising HUBER+SUHNER (Switzerland),
LEMA/EPFL (Switzerland), TU Darmstadt (Germany) and ESTEC/ESA (Netherlands) was created and charged with the investigation and development of small-sized, high-power coaxial connectors. The project duration for the theoretical studies, design and
manufacturing of prototype hardware and the power testing was two years. From this research, HUBER+SUHNER has developed
a space connector that has the dimensions of a standard SMA connector, but in terms of power capability comes close to the
TNC connector. This new male connector is called Power Sub-Miniature (PSM) and is fully optimised with regard to RF-breakdown, corona, multipaction and passive intermodulation effects as well as thermal power dissipation (patents are pending).
Multipaction
Multipaction is a discharge effect that can occur in RF components operating under high power and vacuum conditions. When
free electrons oscillate synchronously with the RF field, an avalanche reaction, i.e. an exponential multiplication of the electron
population can occur and lead to one or several discharges. These discharges lower the impedance and therefore increase the
reflections and, due to the additional loss, the temperature of the device is increased. Sustained multipaction discharges cause
outgassing of the walls and even ionisation breakdown, which may physically damage the device and completely disrupt its performance.
Corona
Corona (ionization) breakdown is an RF gas (such as air) breakdown effect where an initially low electron density increases due to
the acceleration force of the high power RF field, in an avalanche-like manner. This changes the isolating gas into conducting
plasma. As a gas is required for ionisation breakdown, corona effect cannot occur in vacuum like multipaction. Most likely corona
occurs at low pressures around 100 Pascal corresponding to an altitude of 10 to 50 km.
Breakdown must be considered for ground, airborne and some space components, because RF components operating in space
often have to be tested on the ground at full power. Additionally they can be required to operate during launch.
PIM
Passive Intermodulation (PIM) is an interference effect that always occurs when two or more RF-signals are combined in RF devices like cables, connectors and filters. The origin of the interference is a non-linearity of the devices. In high-power multichannel
systems, these nonlinearities generate higher order harmonics of the fundamental frequencies. At least two fundamental signals
and their harmonic product mix together to generate a predictable set of new frequencies with power levels that depend on the
powers of the fundamental signals and especially on the degree of non-linearity of the devices. The result is that certain parts of
the frequency spectrum become unusable for the receive portion of the communication system. Very low PIM power levels are
sufficient for this effect, i.e. sometimes as low as -120dBm (10-15W) .
While careful allocation of receive and transmit frequencies can help to avoid this problem, spectrum crowding and assigned
frequency allocation may make this impossible.
PSM connectors have been developed taking in account these three physical limitations for best performance in the different applications.

PSM - Space flight Power Sub Miniature connectors
Electrical data
A new kind of low weight, high power PSM connector for
space application. This PSM connector combines the lowweight characteristics of the SMA and the high power capability of the TNC connector.
The standard SMA connector is used worldwide in a variety of
applications in large quantities. For space applications, however, this type of connector is severely limited in microwave
CW power capability. This is due to the design of the connector which is not optimised for corona, multipaction and simple
overheating effects. For any application with 10 W or more
CW power, space grade TNC connectors have to be used
that are much larger and heavier and, in many cases, oversized for the application.
