Description

The SM4T is a termination insensitive mixer,

designed for use in military, commercial 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.
