In this paper, we present different types of reconfigurable RF MEMS based matching networks intended for frequency-agile (multi-band) LNAs. Measured results of 2-bits matching networks show a centre frequency tuning range of 2-3 GHz (10-13%) around 20 GHz and 1.5-2.0 dB of minimum losses. Simulated tunable LNA results based on measured data of the RF MEMS matching networks show the possibilities of...
This paper presents a novel high-frequency filter concept based on a single MEMS capacitive shunt structure using meander arm inductance. Tuning ranges of the central frequency in the order of 55% are experimentally demonstrated for filters operating between 13.5 GHz to 30 GHz and 17 GHz to 37 GHz. A low transmission loss of 0.44 dB and a rejection level of -20.5 dB at 17 GHz are reported. The outstanding...
Two tunable matching networks, one with three bits and one with six bits, are designed, fabricated and measured. The tuning elements of the networks are the Radant RMSW-100 SPST MEMS switches. These switches connect fixed line- loading capacitances to the networks. Tapered transmission lines are used instead of uniform lines in the networks. The 6-bit network exhibits two bands with bandwidths of...
