Description:
The AD8302 is a fully integrated RF IC that measures the amplitude and phase between two independent input signals. The device operates from low frequencies to 2.7 GHz. The AD8302 contains two precision-matched wideband log amps, a wideband linear multiplier/phase detector, a 1.8V precision voltage reference, and an analogue output proportional operation circuit. The input signal range is -60 dBm to 0 dBm (reference impedance 50Ω) with a corresponding dynamic range of 60 dB. The AD8302 output provides accurate amplitude measurements in the +/-30dB range with a slope of 30mV/dB, and a phase measurement range of 0 to 180° with a slope of 10mV/degree.
