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.
