ADF5901WCCPZ

The ADF5901WCCPZ from Analog Devices is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) specifically designed for radar applications. It integrates a 24 GHz voltage-controlled oscillator (VCO) with a programmable gain amplifier (PGA) and dual transmit (Tx) channels.

Key features include a 24 GHz VCO that generates the signal for the Tx channels and the local oscillator (LO) output. Each Tx channel is equipped with a power control circuit. The device offers a 2-channel PA with 8 dBm output power and 2-channel muxed outputs with a mute function. It also provides a programmable output power, an N divider output for frequency discrimination, and a 24 GHz LO output buffer. The signal bandwidth is 250 MHz.

For monitoring and control, the ADF5901WCCPZ includes a power control detector, an auxiliary 8-bit ADC, and an on-chip temperature sensor with ±5°C accuracy. All on-chip registers are controlled via a simple 4-wire serial peripheral interface (SPI). The MMIC is qualified for automotive applications and comes in a compact 32-lead, 5 mm × 5 mm LFCSP package, suitable for surface mount.

Applications for the ADF5901WCCPZ include automotive radars, industrial radars, microwave radar sensors, industrial sensors, precision instrumentation, tank level sensors, smart sensors, and commercial sensors for object detection and tracking. It is also used in collision avoidance systems for vehicles and UAVs, and intelligent transportation systems for traffic monitoring and control.
