Overview
The ADF5902WCCPZ-RL7 is a 24 GHz, ISM band, multichannel Frequency Modulated Continuous Wave (FMCW) radar transmitter produced by Analog Devices Inc. This monolithic microwave integrated circuit (MMIC) is designed for high-performance radar applications, particularly in automotive and industrial sectors. The device features an on-chip, 24 GHz voltage-controlled oscillator (VCO) with a fractional-N frequency synthesizer, enabling precise waveform generation and high-frequency resolution. It includes dual transmitter channels, each with power control circuits, and an on-chip temperature sensor. The ADF5902 is controlled via a simple 4-wire serial peripheral interface (SPI) and is packaged in a compact 32-lead Lead Frame Chip Scale Package (LFCSP).
