• Evaluation Board for AD8302, LF-2.7GHz RF/IF Gain and Phase Detector. The AD8302-EVALZ Evaluation Board offers the opportunity to experiment with the AD8302. This is a fully integrated RF IC for measuring Amplitude and the Phase between two independent input signals. The device can be used from low frequencies up to 2.7GHz. The AD8302 integrates two closely matched wideband logarithmic amplifiers, a wideband linear multiplier / phase detector, precision 1.8V reference, and analogue output scaling circuits. The applied input signal can range from -60dBm to 0dBm (ref 50Ω), which corresponds to a 60dB dynamic range. The AD8302 output provides an accurate amplitude measurement over ±30dB range scaled to 30mV/dB and the phase measurement over a 0 to 180° range scaled to 10mV/°. The device has been tested for use over the common Cellular bands (900MHz, 1.8GHz, 2.2GHz) and specified for operation out to 2.7GHz. Measures Independently both Gain/Loss and Phase Operation from Low frequencies up to 2.7GHz Dual Matched Logarithmic Amplifiers with Phase Detector Gain Measurement range -30dB to +30dB Phase Measurement range from 0 to 180° degrees Integrated Voltage Reference and Output Voltage Circuits Single Power Supply 2.7V to 5.5V
