Overview
The AD8302ARUZ-REEL, produced by Analog Devices Inc., is a fully integrated RF/IF gain and phase detector. This component is designed to measure gain/loss and phase in various receive, transmit, and instrumentation applications. It operates over a wide frequency range from 0 Hz to 2.7 GHz and can handle input signals ranging from –60 dBm to 0 dBm in a 50 Ω system. The AD8302ARUZ-REEL requires a single supply voltage of 2.7 V to 5.5 V and is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) configuration.
