ADL5320
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.
