    Abstract

    In this paper, we present GaAs MMIC based reconfigurable RF MEMS impedance matching networks for highly integrated (potentially single-chip) frequency-agile LNAs and adaptive multi-band front-ends. Such GaAs MMIC based RF MEMS LNA matching networks have been realized with a frequency tuning range of 40% (10-16 GHz and 15-23 GHz, respectively) and 1-3 dB of in-band losses. Simulated tunable LNA results based on measured data of GaAs MMIC MEMS matching circuits (and simulated data of MEMS matching networks made on quartz) show the potential of achieving a high gain and low in-band noise figure over such wide tuning ranges
