Monolithic Silicon Bipolar, Measurement of Amplitude / Phase

.

*

**

**

The 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 2.7 GHz.

The AD8302 integrates two closely matched wideband logarithmic amplifiers, a wideband linear multiplier / phase detector, precision 1.8 V reference, and analog output scaling circuits.

The applied input signal can range from -60 dBm to 0 dBm ref 50 Ω, which corresponds to a 60 dB dynamic range.

The AD8302 output provides an accurate amplitude measurement over ±30 dB range scaled to 30 mV/dB and the phase measurement over a 0 to 180° range scaled to 10 mV/°.

The device has been tested for use over the common Cellular bands 900 MHz, 1.8 GHz, 2.2 GHz and specified for operation out to 2.7 GHz.

The AD8302 is supplied in 14-lead Thin Shrunk Small Outline TSSOP package, and fully specified over -40 to 85°C temperature range.
