The AD8302 is a fully integrated system for measuring gain/loss and phase up to 2.7 GHz. It features dual demodulating log amps and phase detector, provides a wide input range of -60 dBm to 0 dBm, offers high accuracy gain and phase measurement, operates from supply voltages of 2.7 V–5.5 V and provides a stable 1.8 V reference voltage output.
The AD8302 is a fully integrated system for measuring gain/loss and phase from DC to 2.7 GHz. It operates from a single 2.7 V–5.5 V supply and accepts ac‑coupled inputs from –60 dBm to 0 dBm in a 50 Ω system. The device outputs accurate gain measurements (±30 dB range, 30 mV/dB) and phase measurements (0°–180°, 10 mV/°).
The handbook includes a functional block diagram, a complete list of specifications, absolute‑maximum ratings, pin configuration and function tables, typical performance curves, and an evaluation‑board schematic. It also describes controller and comparator modes and provides recommended external components for filtering and termination.
