AD8314 is a low-cost RF signal measurement and control subsystem operating from 100 MHz to 2.7 GHz with a typical dynamic range of 45 dB, intended for use in a wide variety of cellular handsets and other wireless devices. It provides a wider dynamic range and better accuracy, rapid response time, low power consumption.
The AD8314 RF Detector/Controller integrates detection and control functions for wireless handsets and other devices. It operates from 100 MHz to 2.7 GHz, provides a linear‑in‑dB response, and consumes low power (12 mW at 2.7 V, 20 pA in power‑down).
The device offers two voltage outputs (V_UP for measurement and V_DN for control), selectable packages (8‑lead MSOP or LFCSP), and a range of pin functions for easy integration. Detailed specifications, absolute maximum ratings, and application notes are included in the document.
