Device Overview

General Description

MMH-35120H is a GaAs MMIC balanced harmonic mixer that features excellent conversion loss, superior isolations, and spurious performance across an incredibly broad bandwidth utilizing the 3rd harmonic of the LO. The MMH-35120H works well as both an up and down converter from the Ka band through mmWave/G band. The MMH-35120H is recommended for mmWave frequency conversion applications where a mmWave LO source may not be available. It is available as both wire bondable die and as a connectorized module.
