AD8302ARUZ is a fully integrated system for measuring gain/lossand phase in numerous receive, transmit, and instrumentationapplications. It requires few external components and a singlesupply of 2.7 V–5.5 V. The ac-coupled input signals can rangefrom –60 dBm to 0 dBm in a 50 Ω system, from low frequenciesup to 2.7 GHz. The outputs provide an accurate measurementof 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, whichmay optionally be reduced by the addition of external filtercapacitors. The AD8302 can be used in controller mode toforce the gain and phase of a signal chain toward predeterminedsetpoints.
