Overview
The ADF5901ACPZ is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) designed by Analog Devices Inc. This component is specifically tailored for radar systems and features an on-chip, 24 GHz Voltage-Controlled Oscillator (VCO) with a Programmable Gain Amplifier (PGA) and dual Tx channels. The VCO generates the 24 GHz signal for the two Tx channels and the Local Oscillator (LO) output. The device also includes power control circuits for each Tx channel and an on-chip temperature sensor. Control of all on-chip registers is managed through a simple 4-wire interface.
