Receiver down-converter MMIC uses 50% less power for 3dB improvement

Each of the device’s four on-chip receive channels use a simple, single-ended connection to four individual antennas, which simplifies RF-transmission-line design and PCB layout, and reduces board size. The receiver down-converter then simultaneously handles four receive signals directly to produce a high-quality, high-amplitude baseband signal that easily connects to one of ADI’s four-channel ADCs. The ADF5904 also incorporates an integrated temperature sensor that eliminates the need for discrete sensing components that otherwise can require additional time and resources to calibrate during system assembly and test.

The ADF5904 is designed for multi-channel receiver, high-frequency applications that use digital beam forming, such as automotive ADAS, microwave radar sensors, and industrial radar systems – environments where energy efficiency is becoming a more important system-level design consideration. The ADF5904 24GHz receiver enables these and other sensor applications by offering best-in-class receive sensitivity while using less overall power than competing RF technologies.
