ADF5904ACPZ

Overview

The ADF5904ACPZ is a four-channel, 24 GHz receiver downconverter MMIC designed for high-performance RF applications. It operates within the 24 GHz to 24.25 GHz frequency range and features an LO input of 24 GHz to 24.25 GHz. Key electrical parameters include a gain of 22 dB, a noise figure of 10 dB, and a P1dB compression point of -10 dBm. The device has an OIP3 of 0 dBm and requires a 3.3 V supply with a current draw of 170 mA. It supports a signal bandwidth of 250 MHz and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent receive channels with single-ended RF inputs connected to internal baluns and differential LNAs.
• Includes an on-chip temperature sensor with +/- 5°C accuracy to eliminate external calibration requirements.
• Features integrated differential output buffers for direct connection to downstream ADCs.
• Provides RX-to-IF isolation of 30 dB to minimize interference between channels.

Applications

• Automotive ADAS systems utilizing digital beamforming
• Microwave radar sensors
• Industrial radar systems

Procurement Notes

Verify the specific suffix (ACPZ) against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Ensure that the ordering information matches the required LFCSP-32 plastic package dimensions. Cross-reference the part number with official Analog Devices distribution channels to confirm current availability and lead times, as supply status may vary by region.

Selection Notes

Select this component when a multi-channel, low-power solution is required for 24 GHz radar or sensing applications. The integrated architecture simplifies PCB layout by reducing the need for external baluns and discrete components. Consider the 10 dB noise figure and 22 dB gain for sensitivity requirements. Evaluate the power consumption profile against system energy constraints, noting the low standby and active modes available in the family.

Part Context

The ADF5904ACPZ belongs to the ADF5904 series of highly integrated receiver downconverters from Analog Devices. This series targets mmWave applications where size, power, and performance are critical design factors. The device represents a shift towards monolithic integration of multiple channels, replacing traditional discrete front-end solutions with a compact 5x5 mm LFCSP package.
