MEMS capacitive series switch fabricated using PCB technology
In this article, an RF MENIS capacitive series switch fabricated using printed circuit processing techniques is discussed. Design, modeling, fabrication, and characterization of the CPW series switch are presented. An example CPW series capacitive switch with insertion loss less than 0.5 dB in the frequency range of 13-18 GHz and isolation better than 10 dB up to 18 GHz is discussed. The switch provides a minimum insertion loss of about 0.1 dB at the self-resonance frequency of 16 GHz and a maximum isolation of about 42 dB at 1 GHz.
