Product Summary
The AD8302ARUZ 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 AD8302ARUZ outputs 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. Both subsystems have an output bandwidth of 30 MHz, which may optionally be reduced by the addition of external filter capacitors. The AD8302ARUZ can be used in direct control mode to servo gain and phase of a signal chain toward predetermined setpoints.
