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
applications, including
WCDMA.
The ADL5320 operates with 5V supply voltage with a supply
current of 104 mA.
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.
