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.

Preliminary Technical Data
EVALUATION BOARD
ADL5321
The basic connections for operating the ADL5321 are shown in
Figure 8. The inputs and outputs should be ac coupled with
appropriately sized capacitors. DC bias is provided to the
amplifier via an inductor connected to the RF output pin. A bias
voltage of 5 V is recommended.
