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.
