Dual-Band Power Amplifier Using Composite Right/Left-Handed Transmission Line

This paper proposes a dual-band power amplifier employing composite right/left-handed transmission line. The two operating frequencies of the power amplifier are achieved by the nonlinear phase slope and other characteristics of CRLH-TL, which can make an arbitrary selection. The operating frequencies are chosen 950MHz and 1900 MHz in this paper. Through the ADS optimum design, the maximum PAE of 64.862% and 61.437% are obtained at 950MHz and 1900MHz, respectively. The output power obtains 45.618dBm and 48.007dBm at the two frequencies. The gain flatness can maintain ±1 in the 900～1000MHz and 1860～1940MHz.
