摘要：
Reconfigurable radio frequency (RF) circuits win be the predominant solution for future global and compact mobile terminals. Recent progress in RF-microelectromechanical systems (MEMS) devices has bolstered the hope for the implementation of high-performance reconfigurable RF circuits. This paper presents configurations for a novel band-reconfigurable power amplifier, a reconfigurable isolator, and a center frequency and bandwidth tunable filter. These RF circuits were prototyped. The reconfigurable power amplifier using MEMS switches achieves comparable performance to that of a single-band power amplifier in four different frequency bands. The isolator and the filter prototypes confirm the feasibility of the proposed configuration. These reconfigurable RF circuits Will contribute to band-free operation in future mobile terminals.
