GENERAL DESCRIPTION
The ADL5323 is a high linearity GaAs driver amplifier that is
internally matched to 50 Ω for operation in the 1700 MHz to
2400 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 preamplifier in a
multicarrier base station power amplifier. Matching and biasing
are all on-chip. The ADL5323 is available in a Pb-free, 3 mm ×
3 mm, 8-lead LFCSP with an operating temperature of
−40°C to +85°C.
