Description: 
RF MEMS based switch matrices have several advantages compared to the mechanical or solid-state switch based ones for space applications. They are compact, light and less lossy with a high linearity up to high frequency. In this work, a 12× 12 switch matrix with RF MEMS and LTCC technologies is presented based on the planar Beneš network. The simulated performance of the 12× 12 switch matrix is below− 12 dB IL (Insertion Loss) up to C band and− 15 dB RL (Return Loss) up to Ku band. Moreover, it has a good isolation better than− 50 dB. A 4× 4 switch matrix with the same design process and technologies is fabricated and measured to verify the 12× 12 switch matrix design process. The measured performance agrees very well to the simulations.
