AD8361 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains, up to 2.5 GHz. It features calibrated rms response, excellent temperature stability, and a wide input range.
The AD8361 is a mean‑responding power detector designed for high‑frequency receiver and transmitter signal chains up to 2.5 GHz. It operates from a single supply of 2.7 V to 5.5 V and provides a linear‑responding DC output with a conversion gain of 7.5 V/V rms. The device offers three reference modes—ground, internal, and supply—to accommodate different ADC requirements.
The datasheet includes detailed specifications, pin configurations, typical performance curves, and application notes such as CDMA and W‑CDMA measurements. An evaluation board is described with configurable options for power‑down, reference mode selection, and input coupling. Absolute maximum ratings, temperature ranges, and recommended ESD handling are also provided.
