GENERAL DESCRIPTION

The ADL5321 is a broadband, linear driver RF amplifier that

operates at frequencies from 2.3 GHz to 4.0 GHz. The device

can be used in a wide variety of wired and wireless applications

including LTE

, WiMAX, WiBro, and WLL.

The ADL5321 operates with a 5V supply voltage, while only

consuming 84 mA of current.

The ADL5321 is fabricated on a GaAs HBT process. The device is

packaged in a low-cost SOT−89 that uses an exposed paddle for

excellent thermal impedance. It operates from −40°C to +85°C,

and a fully populated evaluation board is available.

The ADL5320 is a companion part that offers lower frequency

operation from 400 MHz to 2700 MHz.
