Description

The M85 is a double balanced mixer, designed for use in military,

commercial and test equipment applications. The design utilizes

Schottky ring quad diodes and broadband soft dielectric and

ferrite baluns to attain excellent performance. This mixer can also

be used as a phase detector and/or bi-phase modulator since the

IF port is DC coupled to the diodes. The use of high temperature

solder and welded assembly processes used internally makes it

ideal for use in manual, semi-automated assembly. Environmental
