Compact low-loss high-performance single-pole six-throw RF MEMS switch design and modeling for DC to 6 GHz

Layered axial force coupled membrane based metal contact single-pole quad-throw RF MEMS switch: design, RF performance and mechanical modeling

“…2. The membranes on the same side are coupled in pairs (Farinelli et al 2012;Singh and Rangra 2015). Hence to conduct the signal between input port 1 and any one of the output port 2-5, the metal-contact switch in the respective port can be turned ON (actuated) to route the signal from input to that actuated output port, and this will automatically turn the switch coupled to it to OFF state due to axial force.…”

“…The performance is simulated between input port (Port 1) and output ports (Port 2-4). The output signal can be taken from any port provided that whatever port is excited by bias voltage (Lee et al 2005;Singh 2015;Singh and Pashaie 2014;Singh and Rangra 2015) …”

Modeling Method of Finite Element Modeler and Electromagnetic Solvers for Education and Research in RF MEMS

“…Two bandwidths a and b are considered, Bandwidth a is 30 GHz and has the complete frequency range of K and Ka band that shows more than 60 dB of isolation and bandwidth, b is 7 GHz narrow bandwidth that shows excellent isolation of above 70 dB from 25 GHz to 32 GHz. The solution to the RF problems thus can easily be solved by using EM solver as demonstrated [19].…”
