Description
The sampling phase detector (SPD) module is a hybrid circuit providing a fast step recovery diode, coupling capacitors and a low barrier
Schottky pair. The
Schottky pair is used as a sampling circuit turned on by the fast step from the step recovery diode (SRD), or in the frequency domain, the
Schottky acts as a mixer to mix the harmonic of the SRD step closest to the microwave frequency. The output is a beat frequency (the difference between the harmonic of the reference and the microwave frequency) and is just a DC voltage at the lock point. It is used to phase lock DRO’s and VCO’s from 10 to 1000 MHz typical reference frequencies.
