ADL5321是一款宽带、线性驱动器RF放大器，工作频率范围为2.3 GHz至4.0 GHz。该器件适合各种有线和无线应用，包括ISM、WLL、PCS、GSM、CDMA和W-CDMA。
ADL5321采用5 V电源供电，电源电流为90 mA。
ADL5321采用GaAs HBT工艺制造而成。该器件采用低成本SOT-89封装，使用裸露焊盘，热阻性能出色。工作温度范围为?40°C至+105°C，同时提供配置齐全的评估板。
ADL5320 是ADL5321的配套器件，工作频率范围为400 MHz至2700 MHz，两款器件具有类似性能。
ADL5321-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a single 5 V/300 mA supply. The 5 V supply should be connected to the test loops labeled VCC and GND. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT. To facilitate tuning for different frequencies, the RF input and RF output traces are free of solder mask and have index markings for ease of component placement. The evaluation board ships with tuning components that are optimized for operation from 2500 MHz to 2700 MHz. The ADL5321 data sheet provides recommended tuning components for other frequencies.
