ADF5904WCCPZ

Overview

The ADF5904WCCPZ is a four-channel, 24 GHz receiver downconverter MMIC designed for digital beamforming applications. It operates within the 24 GHz to 24.25 GHz frequency range with a gain of 22 dB and a noise figure of 10 dB. The device features a P1dB compression point of -10 dBm and an OIP3 of 0 dBm. Power consumption is 0.5 mW per channel when all four channels are active. It supports an LO input range from -8 dBm to +5 dBm and provides RF signal bandwidth of 250 MHz. The component utilizes a 32-pin LFCSP-32 package measuring 5 mm x 5 mm with a height of 0.73 mm.

Feature Summary

• Integrates four independent receive channels with single-ended connections to simplify RF transmission line design and PCB layout.
• Includes an on-chip temperature sensor with ±5°C accuracy to eliminate the need for discrete detection components during calibration.
• Provides high linearity and low noise performance suitable for direct connection to four-channel analog-to-digital converters.

Applications

• Automotive Advanced Driver Assistance Systems (ADAS)
• Microwave radar sensors
• Industrial radar systems

Procurement Notes

Verify the specific suffix 'W' against the official Analog Devices datasheet to confirm the exact package variant and material specifications. Ensure compatibility with the required SPI interface configuration for control signals. Cross-reference the operating voltage range of 3.135 V to 3.465 V with the system power supply design. Confirm that the LFCSP-32 thermal pad requirements align with the target PCB copper area for adequate heat dissipation during continuous operation.

Selection Notes

Select this component for multi-channel receiver architectures requiring high integration and low power consumption at 24 GHz. It is appropriate for designs prioritizing reduced board space through simplified single-ended antenna connections. Consider the integrated temperature sensor if system calibration resources are limited. Evaluate the 250 MHz bandwidth against the required signal processing capabilities of the downstream ADCs.
