Hyperfrequency power limiter with capacitive radiofrequency MEMS switches

摘要

The limiter has a signal transmission line for transmitting a microwave frequency signal from an input of a limiting device toward an output of the limiting device. The signal transmission line forms an electrostatic electrode for actuating switches i.e. micro-electro-mechanical system (MEMS) switches. One of the switches comprises a direct mode at the microwave signal frequency applied in the input of the limiting device. The other switch is placed downstream from the former switch, where two switches comprise same continuous actuation.
