Abstract:

We propose the implementation of a widely reconfigurable broad-band power attenuator for Radio Frequency (RF) and Microwave signals, entirely based on the RF-MEMS surface micromachining technology available at FBK in Italy. The network realizes a large number of attenuation levels, from 2 up to 20 dB, with very flat characteristic up to 30 GHz.
