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. Advanced
transformer design yields improved VSWR.
