Description
The SM4T 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. Environmental screening
available to MIL-STD-883, MIL-STD-202, or MIL-
DTL-28837, consult factory.
