Description

The CSM4TH 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 degrada-

tion due to external VSWR mismatches. The use of high tem-

perature solder and welded assembly processes used internally

makes it ideal for use in semi-automated and automated assem-

bly. Environmental screening available to MIL-STD-883, MIL-

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