Abstract

A dual-band Class-E power amplifier using composite right/left-handed transmission lines is proposed. Dual-mode operation is achieved by the frequency offset and nonlinear phase slope of CRLH TL for the matching network of power amplifiers. The frequency ratio of two operating frequencies is not necessarily an integer. Two operating frequencies are chosen 836MHz and 1.95GHz in this work. The simulated results show that output power of 24.9 and 24.1 dBm was obtained at 836MHz and 1.95GHz, respectively. In terms of maximum PAE, we obtain 48.63% and 48.29% at two operating frequencies
