MSPD2018-E50
Sampling Phase Detector Modules
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, or in the frequency domain, the Schottkys act 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 (TYP) reference frequencies.
