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.
