Overview
The ADF5901ACPZ-RL7, produced by Analog Devices Inc., is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) designed for radar systems. This component integrates a 24 GHz voltage-controlled oscillator (VCO) with a power gain amplifier (PGA) and dual transmit (Tx) channels. The on-chip VCO generates the 24 GHz signal for the two Tx channels and the local oscillator (LO) output. Each Tx channel includes a power control circuit, and the device also features an on-chip temperature sensor. Control of all on-chip registers is managed through a simple 4-wire interface. The ADF5901 is packaged in a compact 32-lead, 5 mm × 5 mm Lead Frame Chip Scale Package (LFCSP).
