AD8302:  2.7GHz RF / IF Gain Phase Detector

Product Description

Monolithic Silicon Bipolar, Measurement of Amplitude / Phase

The AD8302 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 analog output scaling circuits.

The applied input signal can range from -60dBm to 0dBm (ref 50ohm), 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 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 AD8302 is supplied in 14-lead Thin Shrunk Small Outline (TSSOP) package, and fully specified over -40 to 85 degC temperature range.
