MMIC radar transmitter with an on-chip and VCO

Analog Devices ADF5902 24GHz Radar Transmitter is a Monolithic Microwave Integrated Circuit with an on-chip, 24GHz voltage Controlled Oscillator. The VCO provides a fractional N-frequency synthesizer with waveform generation ability, a PGA, and dual transmitter channels for radar systems. The on-chip, VCO produces the 24GHz signal for the two transmitter channels and the LO output. Each transmitter channel comprises a power control circuit. An on-chip temperature sensor is also included. Control of all the on-chip registers is through a simple, four-wire SPI. The device is provided in a compact, 32-lead, 5mm x 5mm LFCSP package. The device is ideal for automotive radars, industrial radars, and microwave radar sensors.
