摘要：
In this paper, we propose a 10 W dual-band power amplifier with composite right/left-handed (CRLH) structure. CRLH is based on the metamaterial theory, and it has dual frequency tuning capability. As such, power amplifiers with CRLH structure can operate at two separate frequencies. In this study, we designed a power amplifier operating at 0.7 GHz and 1.5 GHz and supporting dual mode operation: Class AB at 0.7 GHz and Class J at 1.5 GHz. As a result, the amplifier has 67.26% of efficiency and 39.79 dBm of the output power at 0.7 GHz, while at 1.5 GHz it shows 73.35% and 40.5 dBm, respectively.
