Introduction

The Sampled 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 functions as a sampling circuit, switched on by the fast step of the step recovery diode (SRD); in the frequency domain, the Schottky pair acts as a mixer, mixing the harmonic of the SRD step closest to the microwave frequency. The output is the beat frequency (the difference between the reference harmonic and the microwave frequency), which is simply a DC voltage at the lock point. It is used for phase-locking dielectric resonator oscillators (DROs) and voltage-controlled oscillators (VCOs) with typical reference frequencies of 10 to 1000 MHz.
