Description

The M8T 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. Environmental screening

available to MIL-STD-883, MIL-STD-202 or MIL-DTL-28837, con-

sult factory.
