Device Overview

General Description

The MM1-0626HCSP2 is a highly linear passive GaAs double balanced MMIC mixer suitable for both up and down-conversion applications. As with all Marki Microwave mixers, it features excellent conversion loss, isolation and spurious performance across a broad bandwidth and in a small form factor. The MM1-0626HCSP2 is available in a lead-free, RoHS compliant 2.5x2.5 mm chip scale surface mount package (CSP2) and is compatible with standard leaded and lead-free PCB reflow soldering processes. The MM1-0626HCSP2 is a smaller alternative to the standard MM1-0626HSM.

Port Configuration and Functions

Port Diagram

A bottom-up view of the MM1-0626HCSP2's CSP2 package outline drawing is shown below. The MM1-0626HCSP2 has the input and output ports given in Port Functions. The MM1-0626HCSP2 can be used in either an up or down conversion application. For configuration A, input the LO into pin 1, use pin 3 for the RF, and pin 2 for the IF. For configuration B, input the LO into pin 3, use pin 1 for the RF, and pin 2 for the IF.
