ADF5904ACPZ-RL7

Overview

The ADF5904ACPZ-RL7 is a four-channel, 24 GHz receiver downconverter MMIC designed for non-IQ applications. It integrates four independent receive channels with single-ended connections to external antennas, simplifying RF transmission line design and PCB layout. The device features a 10 dB noise figure, 22 dB RX channel gain, and -10 dBm P1dB compression point. It operates with an LO input range of -8 dBm to +5 dBm and supports an RF signal bandwidth of 250 MHz. Power consumption is 0.5 mW per channel when all four are active. The component includes an on-chip temperature sensor with ±5°C accuracy and provides 30 dB RF-to-IF isolation.

Feature Summary

• Integrates four independent receive channels with single-ended antenna interfaces to reduce RF trace complexity
• Includes an on-chip temperature sensor eliminating the need for discrete calibration components
• Provides high linearity and low noise performance suitable for multi-channel receiver architectures

Applications

• Automotive ADAS systems utilizing digital beamforming
• Microwave radar sensors operating at 24 GHz
• Industrial radar systems requiring multi-channel reception

Procurement Notes

Verify availability status as supply may be limited or subject to factory special orders. Confirm RoHS compliance details through official documentation. Ensure the LFCSP-32 package variant matches your PCB footprint requirements. Validate that the non-IQ architecture aligns with your baseband processing capabilities before integration.

Selection Notes

Select this component for applications requiring simultaneous processing of four 24 GHz signals without I/Q demodulation. The single-ended input configuration reduces board space compared to differential designs. Consider the integrated temperature sensor if system calibration resources are constrained. Ensure the 250 MHz bandwidth meets your specific signal processing needs.

Part Context

This part belongs to the ADF5904 series of highly integrated receiver downconverters from Analog Devices. It is specifically engineered for 24 GHz frequency bands, targeting automotive and industrial sensing markets. The device represents a shift towards lower power consumption and smaller form factors in multi-channel radar front-ends.

Replacement Considerations

Check for updated suffixes such as -RL7 which indicates reel packaging. Verify if newer revisions offer improved thermal characteristics or updated pinouts. Consult official substitution guides for any legacy variants within the same family.
