Abstract

The cellular mobile communication industry has recently been one of the fastest growing industries. This paper presents efficient techniques in the design of switching mode class E power amplifiers by reducing switching losses. A typical class E circuit has been design-optimized for 900 and 1800 MHz. Matching networks are used to reduce power consumption. The simulated results were analyzed in terms of output power, dissipated power in the transistor, and efficiency. Efficiencies higher than 67% could be achieved.
