GENERAL DESCRIPTION
This board is designed to allow the user to evaluate
the performance of the ADF4118 Frequency Synthe-
sizer 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 sup-
plies 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 con-
nect to a pc printer port.
The package also contains windows software to allow
easy programming of the synthesizer.
