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. Base
emitter resistors and refractory/gold metallization.         2. Emitter
