Overview
The HMC966LP4ETR is a compact GaAs MMIC I/Q downconverter produced by Analog Devices Inc. This device is designed for high-frequency applications and is housed in a leadless, RoHS compliant SMT package. It features an LNA followed by an image reject mixer, driven by an active x2 multiplier, which enhances its performance by eliminating the need for a filter following the LNA and reducing thermal noise at the image frequency. The HMC966LP4ETR is ideal for applications requiring high conversion gain, low noise figure, and excellent image rejection.
