Schottky Diodes: MMD 00 Series
Phase Detectors
Description
The MicroMetrics MMD series Phase
Detector is a hybrid circuit design. It
contains a fast step recovery diode,
two coupling capacitors and a
matched Schottky diode pair.
The detectors are available from
2-24 GHz and can be customized.
Applications
The MicroMetrics Phase Detectors
are used in VCO and DRO`s in the
500MHz reference frequencies.
