GENERAL DESCRIPTION

The ADL5606 is a broadband, two-stage, 1 W RF driver

amplifier that operates over a frequency range of 1800 MHz

to 2700 MHz. The device can be used in a wide variety of

wired and wireless applications, including ISM, MC-GSM,

W-CDMA, TD-SCDMA, and LTE.

The ADL5606 operates on a 5 V supply voltage and a supply

current of 362 mA. The driver also incorporates a fast power-

up/power-down function for TDD applications, applications

that require a power saving mode, and applications that

intermittently transmit data.

The ADL5606 is fabricated on a GaAs HBT process and is

packaged in a compact 4 mm × 4 mm, 16-lead LFCSP that

uses an exposed paddle for excellent thermal impedance. The

ADL5606 operates from −40°C to +85°C. A fully populated

evaluation board tuned to 2140 MHz is also available.
