Modular Design of Power Amplifiers

A modular power amplifier concept using the AdrenaLine splitter/combiner that permits amplifier designers to concentrate on higher level design tasks such as linearization techniques
Modular Design of Power Amplifiers Anaren Microwave Inc. E. Syracuse, NY Power amplifier designers today face increased peak power-handling requirements due to the new digital modulation forms used in wideband CDMA (W-CDMA) systems. At the same time, the power amplifiers must meet stricter linearity requirements and the available RF/microwave...
