GENERAL DESCRIPTION
The ADL5605 is a broadband, two-stage, 1 W RF driver
amplifier that operates over a frequency range of 700 MHz
to 1000 MHz.
The ADL5605 operates on a 5 V supply voltage and a supply
current of 307 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 ADL5605 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
ADL5605 operates from −40°C to +85°C. A fully populated
evaluation board tuned to 943 MHz is also available.
