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 ISM, WLL, PCS, GSM, CDMA and
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.

EVALUATION BOARD
The basic connections for operating the ADL5320 are shown in
Figure 9. 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.
