GENERAL DESCRIPTION
This board is designed to allow the user to evaluate
the performance of the ADF4118 Frequency Synthesizer for PLL's (Phase Locked Loops). The block
diagram of the board is shown below. It contains the
ADF4118 synthesizer, a pc connector, TCXO for the
reference input, SMA connectors for the power supplies and RF output. There is also a low pass loop
filter (20kHz) and a VCO (Vari-L VCO190-1960T)
on board. A cable is included with the board to connect to a pc printer port.
The package also contains windows software to allow
easy programming of the synthesizer.

The board is powered from a single 9V battery. The
power supply ciruitry allows the user to choose either 3V
or 5V for the ADF4118 V
supply. The default settings are 3V for the ADF4118 V
and VP, and for the VCO

and 5V for the ADF4118 VP and for the VCO supply. It
is very important to note that the ADF4118 V
never exceed the ADF4118 V
. This can damage the de-

vice.
All components necessary for LO generation are catered
for on-board. The 10MHz TCXO from Vectron provides
the necessary Reference Input. The PLL is made up of
the ADF4118, passive loop filter (20kHz) and the VCO
190-1960T from Vari-L. The output is available at
RFOUT through a standard SMA connector. If the user
wishes they may use their own power supplies and reference input. In this case, they need to insert SMA connectors to as shown on the silkscreen and block diagram.
The AD7706 A/D converter is used to monitor the power
supply voltage and current consumption of the ADF4118.
This helps the user pick the optimum synthesizer settings for
power consumption and also provides an alert if the battery
The software comes on a CD. If the user double clicks on
“setup.exe”, then the install wizard installs the software.
Follow the on-screen directions. The software will be
installed in a default directory called “C:/Program Files/
ADF4XXX/ADF4XXX_rev0”. To run the software,
simply double-click on “adf4XXX_rev0.exe”.
Before the main software screen appears, the Device window appears, which will ask the user to choose which device is being evaluated. Choose the ADF4118 and click
OK.
The Main Interface window will now appear. (See Figure
5)
Click on the Eval Board frame near the top right corner of
the Main Interface window.
The Eval Board window will appear. Choose the EvalADF4118EB1. Click OK.
The data is now set up, and other features can now be
examined by the user.
