Description

The SM4TH is a termination insensitive mixer, designed for use in mili-

tary, 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.
