Gain and phase meter for RF signals

Gain and phase meter between two RF signals built around the AD8302, which compares amplitude and phase from DC up to 2.7 GHz and delivers two voltages — one proportional to the amplitude ratio in dB and one to the phase difference in degrees — directly readable by an ADC.
