RF MEMS Matrices have been implemented within an ESA-ESTEC supported
consortium to release the feasibility of sub-elements useful for more
complicated structures involving several switches, to be implemented for
satellite communications. At this stage, 2 x 2 Matrices have been
developed, by using series ohmic switches for I/O interconnections and
shunt capacitive switches to improve the isolation response. The realised
configurations have been tested in the frequency range (0.045 – 40) GHz.
Insertion Losses as low as -1.5 dB and Return Losses around -40 dB have
been measured at 20 GHz for the 90 degrees path.
