Description

The SM5T is a termination insensitive mixer,

designed for use in military, wireless and test

equipment

applications.

The

design

utilizes

Schottky bridge quad diodes, broadband ferrite

baluns and internal loads to provide excellent

performance without degradation due to external

VSWR mismatches.

Environmental screening available to MIL-STD-883,

MIL-STD-202 or MIL-DTL-28837, consult factory.
