DESCRIPTION
The SD4590 is designed for both analog and
digital cellular base stations over the 800 to 960
MHz frequency range, specifically those systems
requiring 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 emitter resistors and
refractory/gold metallization.
