The AD8314 is a complete low cost subsystem for the measurement and control of RF signals in the frequency range of 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 than possible using discrete components.
The AD8314 is a complete low‑cost subsystem for measuring and controlling RF signals from 100 MHz to 2.7 GHz. It provides a wide 45 dB dynamic range and excellent temperature stability (‑40 °C to +85 °C), making it suitable for cellular handsets and other wireless devices. Two voltage outputs are available: V_UP for measurement mode and V_DN (inverted) for controller applications.
Key features include a typical supply voltage of 2.7 V‑5.5 V, quiescent current of about 4.5 mA, sleep current of 20 µA, and a fast 70 ns response time for a 10 dB step. The device is offered in 8‑lead MSOP and LFCSP packages and includes ESD protection.
