Mini-Circuits SYPD-52W+ SMD Phase Detector: 300-650MHz, 900mV DC, 50Ω
The Mini-Circuits SYPD-52W+ is a 50 Ω, high-output, surface-mount phase detector operating within the 300–650 MHz frequency range, manufactured by Mini-Circuits. This device directly converts the phase difference between two radio frequency (RF) signals of identical frequency (RF1 and RF2) into a proportional DC voltage. Featuring a typical sensitivity of 8 mV/° and a maximum output swing of up to 900 mV, it is well suited for applications such as phase-locked loops (PLLs), amplitude leveling circuits, and frequency or phase monitoring systems.
