RF Power Amplifiers for Wireless Infrastructure Are Still Difficult to Design and Build


RF power amplifiers (RFPAs) for wireless infrastructure basestations and, more recently, remote radio heads (RRH) are still a difficult undertaking. Two characteristics of these sub-assemblies continue to jump out at designers. Linearity and efficiency are the drivers for the design of RFPAs for this application. Multi-carrier signals, increasing use of data, and spectrum issues all require a highly linear amplifier to satisfy the modern wireless infrastructure basestation. Couple this with the need for high RF power amplifier efficiency to reduce primary power usage and simplify cooling systems and add mechanical considerations, and the equation can be quite difficult. These twin issues have been with the industry for the last 20 years or so and things have not gotten easier.
