EVALUATION BOARD HARDWARE
INTRODUCTION
LO INPUT/OUTPUT
The ADRF6620 evaluation board provides all of the support
circuitry required to operate the ADRF6620 in its various
modes and configurations. Figure 2 shows the typical bench
setup used to evaluate the performance of the ADRF6620.
The ADRF6620 offers two alternatives for generating the
differential LO input signal: externally via a high frequency low
phase noise LO signal or internally via the on-chip Fractional-N
synthesizer. In either case, the differential LO signal can be
routed off chip to the SMA connector labeled LO_Output.
POWER SUPPLY
The ADRF6620 evaluation board requires a single +5 V power
supply. Connect the positive power terminal to one of the red
test loops, either VCC1 or VCC2. The ADRF6620 consumes
less than 400 mA at power up with the default register settings.
RF INPUTS
The high isolation 4:1 RF switch and on-chip tunable RF balun
enables the ADRF6620 to support four single-ended 50 Ω
terminated RF inputs. The 4:1 RF switch can be controlled
serially via the SPI port or parallel control using switches S1
and S2. The default configuration is parallel control using the
switches. The operational frequency range of the RF inputs
is from 700 MHz to 2700 MHz and the inputs should be accoupled.
For internal LO configuration using the on-chip Fractional-N
synthesizer, apply a low phase noise reference signal to the
REFIN connector. The PLL reference input can support a wide
frequency range since the division or multiplication blocks can
be used to increase or decrease the reference frequency to the
desired value before it is passed to the phase frequency detector
(PFD). The integrated synthesizer enables continuous LO
coverage from 350 MHz to 2850 MHz.
For optimum performance using an external LO source, the
LO inputs, LOIN and LOIP, should be driven differentially.
Unless an ac-coupled balun/transformer is used to generate
the differential LO, the inputs must be ac-coupled. The input
impedance of the differential LO signals is 50 Ω.

MIXER OUTPUT
transformer from Mini-Circuits, TC4-1W+, to translate the
250 Ω output impedance of the mixer to 50 Ω (see Figure 3).
The mixer outputs of the ADRF6620 are routed off chip for
external biasing and optional low-pass filtering. The output
pins, MXOP and MXON, require supply biasing to +5 V and
the mixer’s differential output impedance is approximately
255 Ω. Refer to the ADRF6620 data sheet for the equivalent
mixer output impedance and recommendations on the interstage filter design. The default configuration of the evaluation
board has the mixer outputs ac-coupled to the IF VGA inputs.
Attention needs to be paid to the IF frequency of the mixer
output and the bandwidth of the transformer. The 1 dB bandwidth of the TC4-1W+ is limited to 100 MHz and the 3 dB
band is 800 MHz. Alternatively, the 4:1 impedance transformer
can be replaced with a 1:1 transformer, such as the TC1-1-13M+,
and the L-resistor network (R33, R34, R32, and R10) can be
used for impedance matching. The tradeoff to this approach is
that the L-network is essentially a voltage divider that results in
power loss.
The ADRF6620 evaluation board provides the option to
monitor the front-end of the ADRF6620 independently from
the variable gain IF amplifier by routing the differential mixer
outputs to the SMA connectors. To achieve this configuration,
remove L5 and L6 and populate C65 and C66 with 0.1 µF. The
MXOP and MXON pins are routed to a 4:1 impedance

If using a 1:1 transformer, populate R32 = R33 = 113 Ω and R34
= R10 = 28 Ω. This configuration results in a voltage loss of

impedance of the signal generator will reflect as 150 Ω at the IF
amplifier’s input after the TCM3-1T+.
The final IF amplifier stage amplifies the mixer outputs by
3 dB to 15 dB in 0.5 dB steps. The default configuration of the
evaluation board has the mixer outputs routed to the IF amp
inputs, however the evaluation board offers the flexibility of
isolating the IF amp independently. To evaluate the amplifier
independently of the mixer, remove C18 and C19 and populate
C70 and C71 with 0.1 µF.
This same principle also holds true for the amplifier’s output
where the spectrum analyzer’s impedance translates to 150 Ω
after the transformer. If the IF amplifier is to be terminated with
a source or load impedance different from what an impedance
transformer can offer, a 1:1 transformer and matching network
can be used.
By design, the IF amplifier has been optimized for OIP3
when the source and load impedance are terminated with
150 Ω. This matched condition can be achieved by using
3:1 impedance transformers at both the IF amplifier’s input
and output (see Figure 4 and Figure 5). The 50 Ω source
If the load or the source resistance is not equal to 150 Ω, refer
to the ADRF6620 data sheet for equations which can be used
to determine the resulting gain and input/output resistances.

EVALUATION BOARD CONTROL SOFTWARE
The ADRF6620 evaluation board is configured with a USBfriendly interface to allow programmability of the ADRF6620
registers.
SOFTWARE REQUIREMENTS
These instructions describe how to install the ADRF6620
control software, as well as the Cypress generic USB driver, onto
a Windows XP, Vista, or Windows 7 computer running either a
32-bit or 64-bit operating system. Install the necessary software
before plugging the USB cable to the computer.
1.
In the extracted folder, ADI_RFG_Drivers, run the
ADI_RFG_Drivers.exe file. Running this file allows the
installation of the Cypress CyUSB.sys driver as a verified,
signed driver.
2.
Run the file ADRF6620_install.exe from the extracted
.zip file. An icon should appear on your desktop with the
Analog Devices, Inc., logo, labeled ADRF6620.
3.

Computer and select Properties. Next, in Vista or
Windows 7, select the Device Manager option. In XP,
select the hardware tab and then Device Manager.
5.
In Device Manager, select the last category, Universal
Serial Bus Controllers. There will be an entry with either a
yellow flag (for unknown device) or ADF4xxx USB Driver
(if you have installed the previous ADRF6x0x or Analog
Devices Limerick PLL software). Right click on this device
and select update driver. Browse to select the directory
C:\Program Files\ADRF6620_customer_software.
6.
Click Next to complete the driver installation successfully.
ADRF6620 EVALUATION SOFTWARE
The ADRF6620 evaluation software offers a block diagram
view of how the registers affect the major functional blocks of
the ADRF6620. The main screen of the evaluation software is
shown in Figure 6.
Before reading or writing to the registers, validate the USB
connection by reading the USB indicators at the lower left
corner of the software. The DUT to GUI button reads the
register values from the device and updates the user interface.
An automatic write to the chip is initiated every time a register
value is changed from the user interface.
The PLL synthesizer blocks perform background calculations;
the user need only specify the PLL reference and desired LO
frequency and the software calculates and sets the INT, FRAC,
and MOD values accordingly. The green boxes require user
input while the yellow boxes are read only.
The Engineering tab, as shown in Figure 7, allows specific
reads and writes to the individual registers. Decimal format is
required when entering data to the address and data fields.
