AD8313 is a 0.1GHz to 2.5GHz 70dB logarithmic detector/controller with wide bandwidth, high dynamic range, high accuracy, fast response, control mode and error output.
The AD8313 is a multistage demodulating logarithmic amplifier that converts RF signals to a decibel‑scaled DC output. It operates from 0.1 GHz to 2.5 GHz, offers a wide dynamic range (up to 70 dB), and can be used in both log (RSSI) and controller modes.
The device is supplied in an 8‑lead MSOP package, works from 2.7 V to 5.5 V, and includes a power‑down feature that reduces current to a few tens of microamps. Typical applications include RF transmitter power‑amp set‑point control, level monitoring, and RSSI measurement for cellular base stations and radar.
