ADF5902WCCPZ

ADF5902 is a 24 GHz transmitter (Tx) monolithic microwave integrated circuit (MMIC) with an on-chip, 24GHz 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, 24GHz VCO generates the 24GHz 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). It is used in application such as automotive radars, industrial radars, microwave radar sensors etc.
