GENERAL DESCRIPTION The ADL5322 is a high linearity GaAs driver amplifier that is internally matched to 50 Ω for operation in the 700 MHz to 1000 MHz frequency range. The amplifier, which has a gain of 20 dB, is 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 ADL5322 is available in a Pb-free, 3mm × 3 mm, 8-lead LFCSP package with an operating temperature from −40°C to +85°C.
