  • Abstract
    A band-reconfigurable power amplifier (PA) is presented that comprises band-switchable matching networks with RF microelectromechanical systems switches. The fabricated triple-band PA achieves the output power of 30 dBm and the power added efficiency of 60% in three different frequency bands, 900 MHz, 1500 MHz, and 2000 MHz. Because the proposed band-reconfigurable PA can be extended to a larger number of frequency bands, it will contribute to "band-free" operation for future mobile terminals.
