The AD8302-EVALZ is an evaluation board for AD8302 RF/IF gain and phase detector. The AD8302 is a 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 2.7V to 5.5V. The AC coupled input signals can range from -60dBm to 0dBm in a 50ohm system, from low frequencies up to 2.7GHz. The AD8302 comprises a closely matched pair of demodulating logarithmic amplifiers, each having a 60dB measurement range. By taking the difference of their outputs, a measurement of the magnitude ratio or gain between the two input signals is available. The AD8302 includes a phase detector of the multiplier type, but with precise phase balance driven by the fully limited signals appearing at the outputs of the two logarithmic amplifiers.
