Termination Insensitive Mixer
Features
• LO 1 TO 3400 MHz

• IF 1 TO 2000 MHz
• LO DRIVE +23 dBm (NOMINAL)
• HIGH INTERCEPT +29 dBm (TYP.)
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.
