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

Software Description
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.
