The ADL5322 is a high linearity GaAs driver amplifier that is internally matched to 50 ohm for operation in the 700MHz to 1000MHz 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.
