GENERAL DESCRIPTION
The ADL5320 is a broadband, linear 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 W-CDMA.
The ADL5320 operates with a 5 V supply voltage and 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, and a fully populated evaluation board is available.
