GENERAL DESCRIPTION

The ADL5320 is a broadband, linear pre-driver RF amplifier

that operates at frequencies from 400 MHz to 2700 MHz. The

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

WCDMA.

The ADL5320 operates with 5V supply voltage with a supply

current of 104 mA.

Figure 1.

The ADL5320 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.

A fully populated evaluation board is also available.
