Abstract
A broadband 0º/180º phase switch based on a slotline-coplanar-waveguide cross loaded with two MEMS switches in opposed (ON/OFF or OFF/ON) states, is reported. The fabrication was made on high-resistivity silicon substrates using the FBK-irst and LAAS-CNRS surface micromachining processes, showing a high repeatability. The measured phase shift is 180º +0º/-7º in the extremely wide frequency range 1–30 GHz.File in questo prodotto:
