Description
The SM5TH 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. The use of high temperature solder and welded assembly processes used internally
makes it ideal for use in semi-automated and automated assembly. Environmental screening available to MIL-STD-883, MILSTD-202, or MIL-DTL-28837, consult factory.
