Product Summary

The AD8302ARU is an innovative, fully integrated system for measuring gain/loss and phase in numerous receive, transmit, and instrumentation applications. It requires few external components and a single supply of 2.7 V–5.5 V. The ac-coupled input signals can range from –60 dBm to 0 dBm in a 50 Ω system, from low frequencies up to 2.7 GHz. The outputs of AD8302ARU provide an accurate measurement of either gain or loss over a ±30 dB range scaled to 30 mV/dB, and of phase over a 0℃–180℃ range scaled to 10 mV/degree. The applications of the AD8302ARU include RF/IF PA Linearization Precise, RF Power Control, Remote System Monitoring and Diagnostics, Return Loss/VSWR Measurements, Log Ratio Function for AC Signals.
