VSWR 3 dB OVERDRIVE CAPABILITY PIN CONNECTION DESCRIPTION The SD4590 is designed for both analog and digital cellular base stations over the 800 to 960 MHz frequency range, specifically those systems re- quiring the high linearity and efficiency afforded by class AB operation. Integrated input/output pre- matching simplifies amplifier design. Ruggedness, MTTF, and linearity are enhanced using diffused 1. Collector 3.
