AD8302 RF Signal Generator RF/IF LF-2.7G

AD8302 converts the amplitude between two independent input signals. It is a fully integrated RF IC that measures and phase. The device operates from low frequencies up to 2.7 GHz. The AD8302 includes two precision-matched wideband log amplifiers, a wideband linear multiplier/phase detector, a 1.8V precision voltage reference, and an analog output proportional operation circuit.

The input signal range is -60 dBm to 0dBm (reference impedance 50Ω), with a corresponding dynamic range of 60dB. The AD8302 output provides accurate amplitude measurements in the +/-30dB range with a slope of 30mV/dB; 0 to 180° phase measurement range with 10mV/degree slope.
