200kHz offset from carrier
GENERAL DESCRIPTION
This board is designed to allow the user to evaluate the
performance of the ADF4213 Frequency Synthesizer for
PLL's (Phase Locked Loops). The block diagram of the
board is shown below. It contains the ADF4213 synthe-
sizer, a pc connector, TCXO reference input, power
supplies and IF/RF outputs. Both output channels have a
20kHz loop filter. The IF channel has a 540MHz VCO
while the RF channel has a 900MHz VCO. 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.
