Device Overview

General Description

MM2D-0528SCSM is a GaAs MMIC triple balanced mixer with high dynamic range and low conversion loss. This mixer offers broad operating bandwidths for applications in the C through Ka bands. The MM2D-0528SCSM has on-chip baluns for the LO and RF ports, while offering differential ports on the IF for flexible operation with an external balun or differential interface. The MM2D-0528SCSM is available in a 4x4 mm QFN package.

Port Configuration and Functions

Port Diagram

A bottom-up view of the MM2D-0528SCSM’s SM package outline drawing is shown below. The MM2D-0528SCSM has the input and output ports given in Port Functions. The MM2D-0528SCSM can be used in either an up or down conversion. Configuration A/B refer to the same part number (MM2D-0528SCSM) used in one of two different ways for optimal spurious performance. For configuration A, input the LO into pin 4, use pin 15 for the RF. For configuration B, input the LO into pin 4, use pin 15 for the RF.
