Fabrication of MEMS Type RF Switch Structure

MEMS형 RF Switch 구조물 제작

This paper presents the structures for a CPW shunt RF switch using MEMS(Micro Electro Mechanical System). Recent development in MEMS technology has made the design and fabrication of micro-mechanical switches as new switching elements. The micro-mechanical switches have low insertion loss, negligible power consumption, and good isolation compared to semiconductor switches. The fabricated structure shows an insertion loss of 2dB at 20GHz When a bias voltages of 12V is apply.
