Device Overview

General Description

The MM1-0212HSM is a GaAs MMIC double balanced mixer that is optimized for low frequency applications. MM1-0212HSM is a low frequency S band mixer that works well as both an up and down converter through X band. This mixer offers low conversion loss and high LO to RF isolations at moderate LO powers. The sister MM1-0212SSM is recommended for applications which demand higher linearity. The MM1-0212LSM is recommend for low power applications. The MM1-0212HSM is available in a 4x4 mm QFN package. Evaluation boards are available.

Port Configuration and Functions

Port Diagram

A bottom-up view of the MM1-0212HSM’s SM package outline drawing is shown below. The MM1-0212HSM has the input and output ports given in Port Functions. The MM1-0212HSM can be used in either an up or down conversion. For configuration A, input the LO into pin 3, use pin 16 for the RF, and port 9 for the IF. For configuration B, input the LO into pin 16, use pin 3 for the RF, and pin 9 for the IF.
