Description

Transformers convert the LO and RF paths to balanced
lines connecting to a low barrier, Schottky diode ring quad.
These transformers help provide excellent isolation between
ports. Conversion loss is low. The direct connection of the
IF port to the diode quad allows these mixers to be used as
phase detectors and bi-phase modulators.
