Analog Devices AD8319 Datasheet
The AD8319 is a demodulating logarithmic amplifier that converts RF input signals from 1 MHz to 10 GHz into a decibel‑scaled output. It can operate in measurement or controller mode, providing a stable log‑conformance over temperature and a wide dynamic range.
Key features include a 45 dB dynamic range up to 8 GHz, 6 ns fall/10 ns rise response time, supply voltage of 3.0 V‑5.5 V, and a compact 2 mm × 3 mm LFCSP package. The device is suited for RF transmitter PA set‑point control, power monitoring, RSSI measurement in base stations, WLAN, WiMAX, and radar systems.
