GENERAL DESCRIPTION
The ADL5322 is a high linearity GaAs driver amplifier that
is internally matched to 50 Ohms for operation in the 700
MHz to 1000 MHz frequency range. The amplifier, which
has a gain of 20 dB, has been specially designed for use in
the output stage of a cellular base station radio or as an
input pre-amplifier in a multi-carrier base station power
amplifier. Matching, biasing as well as input and output
coupling capacitors are all on-chip. The ADL5322 is
available in a Pb-free 3mm x 3 mm 8-pin Chip scale
package with an operating temperature from -40°C to
+85°C.
