Port Configuration and Functions

Port Diagram

A bottom-up view of the MM1-2567LSM-2’s SM package outline drawing is shown below. The MM1-2567LSM-2 has the input and output ports given in Port Functions. The MM1-2567LSM-2 can be used in either an up or down conversion. For configuration A, input the LO into pin 6, use pin 10 for the RF, and pin 3 for the IF. For configuration B, input the LO into pin 10, use pin 6 for the RF, and pin 3 for the IF.
