Description

The M8TH 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

degradation due to external VSWR mismatches. Environmental

screening

available

to

MIL-STD-883,

MIL-STD-202

or

MIL-DTL-28837, consult factory.
