Reconfigurable RF MEMS Switch with Improved Switching Speeds using Push Pull Configuration

The recent advancements in Radio frequency (RF) are brought forward using Micro-machining technology, for being small sized and better performances. There is more scope of improvement as it was most recent field of interdisciplinary field. Among the phase shifters using the MEMS technology are growing its importance when compared conventional shifters by overcoming most of the limitations. But switching speed is always a concernwhen a mechanical actuating element is present that compromises the overall performance of the devices. As DMTL base Shifter most rely on the RF MEMS switches, the speed of switch is governing to overall performance of the phase shifter. In this paper push pull base RF MEMS switch was mechanical altered with triangular cantilevers to improve switching speed. This would find better applications in Reconfigurable DMTL’s that operated at wide band applications. The resonant frequency improvement was carried where 13% of switchingwas improvement for the device.
