RF MEMS adjustable impedance matching network and adjustable power divider

摘要

MEMS applications are gaining wide acceptance in microwave applications. In this paper we present two novel applications of MEMS on well known RF devices: triple stub matching and power divider. Particularly for phased array antennas, controllable components are vital. We have developed a triple stub matching circuit. The stub lengths are electrically adjustable and therefore impedance matching is achieved for any impedance depending on changing conditions such as frequency of operation. This triple stub matching circuit is utilized in the design of an adjustable power divider.
