GENERAL DESCRIPTION

The ADL5604 is a very broadband RF driver amplifier that

operates over the wide frequency range of 700 MHz to 2700 MHz.

The ADL5604 is also highly linear and has a very low power

consumption, enabling the driver to be packaged in a compact

16-lead, 4 mm × 4 mm LFCSP.

For thermal management, the ADL5604 uses an exposed

paddle, and the upper and lower pins of the package are all

grounded, which gives the ADL5604 excellent thermal transfer

characteristics.

The ADL5604 can be quickly powered down or up in 50 ns for

applications requiring TX shutdown, such as TDD systems.

The ADL5604 operates on a single 5 V supply voltage and draws

only 318 mA of supply current.

The driver is fabricated on a GaAs HBT process and operates

from −40°C to +85°C. A fully populated evaluation board is

available.
