This document is a detailed introduction of ADL5570 WiMAX power amplifier, including its features, applications and application guides.
The ADL5570 is a high‑linearity GaAs HBT power amplifier designed for WiMAX terminals operating from 2.3 GHz to 2.4 GHz. It provides a fixed gain of 29 dB, up to 25 dBm output power in high‑power mode, and a power‑added efficiency of 20 % at 25 dBm.
The device operates from a 3.2 V‑4.2 V supply and includes multiple low‑power modes (low‑power, standby, and sleep) to reduce battery consumption. It is packaged in a 4 mm × 4 mm 16‑lead LFCSP and is rated for –40 °C to +85 °C operation. This manual is written in Chinese.
