DESIGN ADVANTAGES OF CDMA POWER AMPLIFIERS BUILT WITH MOSFET TECHNOLOGY

摘要

CDMA power amplifiers are now being produced in volume using MOSFET technology, enabling improvements in amplifier performance and system cost. This article discusses the design characteristics of these very flexible and stable devices and explains how they make it easier to achieve optimal performance for CDMA systems. It also shows how the MOSFET amplifiers facilitate handset designs that operate without isolators, have low RX-band noise generation and achieve high efficiency.
