CSM4TH Termination Insensitive Mixer Rev. V3 Features Product Image LO 1 TO 3400 MHz RF 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.
