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).The ADF5902 comes in a compact, 32-lead, 5 mm × 5 mm LFCSP package.ApplicationsAutomotive radarsIndustrial radarsMicrowave radar sensors
