Device Overview

General Description

The MM1-0212SSM is a highly linear GaAs MMIC double balanced mixer. MM1-0212SSM is a low frequency, high linearity 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 the nominal LO drive. The sister MM1-0212HSM and MM1-0212LSM are recommended for applications which need LO operation at lower powers. The MM1-0212SSM is available in a 4X4 mm QFN package. Evaluation boards are available.

Port Configuration and Functions

Port Diagram

A bottom-up view of the MM1-0212SSM’s SM package outline drawing is shown below. The MM1-0212SSM has the input and output ports given in Port Functions. The MM1-0212SSM 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 pin 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.
