Product Details

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 2.7 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.

Tools & Simulations


Design Tools


ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
