This document introduces the technical information of a 50dB GSM PA controller named AD8311, including its features and characteristics, suitable for controlling RF power amplifiers in the frequency range of 0.1 GHz to 2.5 GHz.
The AD8311 from Analog Devices provides a complete RF detector and gain‑control solution for cellular handsets and other battery‑operated wireless devices. It offers a 50 dB measurement range from 0.1 GHz to 2.5 GHz, temperature‑stable linear‑in‑dB response, and a low‑power supply (2.7 V‑5.5 V).
The device is supplied in a 6‑ball wafer‑level chip‑scale package, consumes 7.6 mA, and includes pins for supply (VPOS), output (VAPC), set‑point input (VSET), filter (FLTR), common (COMM) and RF input (RFIN). Detailed specifications, pin functions, and typical performance graphs are provided.
| Frequency range | 0.1 GHz – 2.5 GHz |
|---|---|
| Supply voltage (VPOS) | 2.7 V to 5.5 V |
| Dynamic range at 0.9 GHz | 51 dB |
The device operates from –40 °C to +85 °C.
