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.
