2.3 GH TO 4.0 GH ¼ Watt RF Driver Amplifier

The ADL5321 is a broadband, linear driver RF amplifier that operates at frequencies from 2.3 GHz to 4.0 GHz. The device can be used in a wide variety of wired and wireless applications, including ISM, WLL, PCS, GSM, CDMA, and W-CDMA.

The ADL5321 operates with a 5 V supply voltage and a supply current of 90 mA.

The ADL5321 is fabricated on the 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 +105°C, and a fully populated evaluation board is available.

The ADL5320 is a companion part to the ADL5321 that operates at similar performance from 400 MHz to 2700 MHz.
