Duplexers
132-174 MHz
Notch
This duplexer is a compact high performance notch-only style duplexer,
ideally suited to installations at uncongested communications sites. It
features low insertion loss, high symmetrical isolation and excellent
stability - all in a small and robust package.
Many other models are available with customised tx-rx frequency
separations to suit specific applications. Please contact your nearest
RFI Sales Office for further assistance.
These duplexers comprise of extruded aluminium resonators and solid
copper jacketed intercabling that ensures excellent mechanical and
electrical stability. Temperature compensation is achieved through
superior cavity design and the careful selection of construction
materials.

Duplexers
132-174 MHz
Pseudo BandPass
This duplexer is ideal for typical VHF repeater base station
applications. It offers excellent insertion loss, isolation and power
rating characteristics in a space-efficient package.
This model comprises four (4) helical resonator filters coupled together
in a pseudo-bandpass configuration offering low insertion loss and high
port-to-port isolation in an optimised design offering a combination of
pseudo-passband selectivity and space-efficient physical dimensions.
This duplexer is made from resonators constructed from extruded
hardened aluminium that is not easily deformed. Excellent tuning
stability is therefore maintained across the guaranteed extended
temperature range. The passivated chromatic conversion coating
(Alodine) provides excellent corrosion protection.

Duplexers
132-174 MHz
Pseudo BandPass/Notch
This duplexer offers higher performance specifications and suits
applications requiring more stringent performance characteristics than
the four (4) cavity model - and with the same quality of design and
construction.
This model comprises six (6) helical resonator filters coupled together
in a pseudo-bandpass/notch configuration offering low insertion
loss and high port-to-port isolation in an optimised design offering
a combination of pseudo-passband selectivity, notch rejection, and
space-efficient physical dimensions.
This duplexer is made from resonators constructed from extruded
hardened aluminium that is not easily deformed. Excellent tuning
stability is therefore maintained across the guaranteed extended
temperature range. The passivated chromatic conversion coating
(Alodine) provides excellent corrosion protection.

132-174 MHz
Pass Reject Duplexer
These duplexers are ideal for VHF repeater base station applications
on congested communications sites.
This model comprises four (4) cavity filters coupled together in a Pass
Reject configuration and offers a pseudo-bandpass response with high
RF Input Power capability, high port-to-port isolation and the ability to
cater for narrow frequency separations.
These duplexers are made from resonators constructed from extruded
hardened aluminium that is not easily deformed. Excellent tuning
stability is therefore maintained across the guaranteed extended
temperature range. The passivated chromatic conversion coating
(Alodine) provides excellent corrosion protection.
These units are supplied on a 3RU rack mount shelf. Other mounting
styles are available on request.

BandPass (T-Pass®)
This duplexer is ideal for VHF repeater base station applications on
congested communications sites. This model comprises four (4) cavity
filters with both coarse and fine tuning controls, coupled together in a
bandpass configuration using T-Pass® loops and therefore offers the
added flexibility of future channel expansion - in addition to rejecting
unwanted frequencies outside its pass band.
The T-Pass® design also provides a high RF Input Power capability.
This duplexer is made from resonators constructed from extruded
hardened aluminium that is not easily deformed. Excellent tuning
stability is therefore maintained across the guaranteed extended
temperature range. The passivated chromatic conversion coating
(Alodine) provides excellent corrosion protection.
• Expandable (uses T-Pass® technology)
