HMC265LM3

RF Mixers Overview

The HMC265LM3 is a GaAs MMIC sub-harmonic mixer down-converter operating from 20 to 31 GHz. It features integrated LO and IF amplifiers within a surface-mount leadless chip carrier package. The device utilizes sub-harmonic pumping (x2) for efficient frequency conversion. Key electrical specifications include a noise figure of 13 dB, with an operating supply voltage range of 3 V to 4 V and a typical current consumption of 50 mA. It supports operation temperatures between -55°C and +85°C.
