Wideband circuits are suitable for reconfigurable transceiver systems, but designing an output matching network for a wide operational bandwidth in order to achieve high efficiency and linearity is a challenging task. In1, a Class-J PA using a lumped π-type output matching network is presented to...
reconfigurable functionpin diodeIn this article, a novel multiresonance small square slot antenna with reconfigurable band-notch performance, for octave-band multiresonance applications is proposed. The proposed antenna consists of a modified radiating stub and a ground plane with two rectangular slots ...
