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