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.

Parameter Rating

Supply Voltage, VSUP 6.5 V
Input Power (50 Ω Impedance) 20 dBm
Internal Power Dissipation (Paddle Soldered) 683 mW
θJC (Junction to Paddle) 28.5°C/W
Maximum Junction Temperature 150°C

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
