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. FUNCTIONAL BLOCK DIAGRAM

EVALUATION BOARD

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.
