Overview
The HMC951BLP4E is a compact GaAs MMIC I/Q downconverter produced by Analog Devices Inc. This device is designed in a leadless RoHS compliant SMT package, making it compatible with surface mount manufacturing techniques. It provides a small signal conversion gain of 13 dB, a noise figure of 2 dB, and 24 dBc of image rejection across the frequency band of 5.6 to 8.6 GHz. The HMC951BLP4E utilizes a low noise amplifier (LNA) followed by an image reject mixer driven by an LO buffer amplifier, eliminating the need for a filter following the LNA and removing thermal noise at the image frequency.
