Overview:

AD8302-EVALZAD8302-EVALZ is a 4-layer, FR4-based printed circuit board. For normal operation, it requires a 5V/50 mA power supply. The 5V power supply should be connected to the vector pins leads labeled VP and GND. The two RF input signals are applied to two edge-mounted SMA type RF connectors (INPA and INPB). The gain and phase output signals are accessible via edge-mounted SMA connectors.

The AD8302AD8302 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 AD8302ARUZ.AD8302ARUZ. integrates two closely matched wideband logarithmic amplifiers, a wideband linear multiplier / phase detector, precision 1.8V reference, and analog output scaling circuits.
The applied input signal can range from -60dBm to 0dBm (ref 50ohm), which corresponds to a 60dB dynamic range.
The AD8302ARUZ.AD8302ARUZ. output provides an accurate amplitude measurement over +/-30dB range scaled to 30mV/dB and the phase measurement over a 0 to 180 degree range scaled to 10mV/degree.
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.
The AD8302ARUZ.AD8302ARUZ. is a fully integrated system for measuring gain/loss and phase in numerous receive, transmit, and instrumentation applications
The AD8302ARUZ.AD8302ARUZ. comprises a closely matched pair of demodulating logarithmic amplifiers, each having a 60 dB measurement range.

Key Applications: RF/IF PA Linearization, Precise RF Power Control, Remote System Monitoring and Diagnostics, Return Loss/VSWR Measurements, Log Ratio Function for AC Signals.
