Reconfigurable millimeterwave filter using stubs and stub extensions selectively coupled using voltage actuated micro-electro- mechanical switches

摘要

A reconfigurable filter system designed using micro-elecro- mechanical (MEM) switches is disclosed. The filter comprises a transmission line with one or more filter stubs coupled to the transmission line by MEM switches. The impedance of the filter system is altered by selectively opening and closing the MEM switches, which alters the filter characteristics of the filter system. Alternatively, the characteristics of the filter system are altered by using the MEM switches to selectively alter the length of filter stubs attached to the transmission line.
