GENERAL DESCRIPTION

The ADF5902 is a 24 GHz transmitter (Tx) monolithic microwave

integrated circuit (MMIC) with an on-chip, 24 GHz voltage

controlled oscillator (VCO). The VCO features a fractional-N

frequency synthesizer with waveform generation capability with

programmable grid array (PGA) and dual transmitter channels

for radar systems. The on-chip, 24 GHz VCO generates the

24 GHz signal for the two transmitter channels and the local

oscillator (LO) output. Each transmitter channel contains a

power control circuit. There is also an on-chip temperature

sensor.

Control of all the on-chip registers is through a simple, 4-wire

serial peripheral interface (SPI).
