Designing a High-Efficiency WC

ABSTRACT
Efficiency is a primary concern in wireless communications and many other industries. Most often, this
sought after efficiency comes at a financial cost. The cellular industry is no different from other business in
its efforts to reduce cost by maximizing efficiency. In the cellular industry, a large portion of the costs are
attributed to base stations. The base station is the infrastructure that is responsible for transmitting and
receiving speech and data between cellular devices. A significant portion of the costs are attributable to
the high power amplifiers (HPA) located within these infrastructures. When a power amplifier (PA) is
operating at higher efficiency, the linearity of the PA is adversely affected. The motivation for this work is
to maximize the efficiency and linearity of HPAs; thus, breaking the adverse relationship between the two.
