In this contribution an RF MEMS based switch matrix for space applications is introduced. RF MEMS switches are an interesting component for satellite applications due to their low power consumption and small size. Therefore an RF MEMS based switch matrix has been developed in conjunction with ESA. The realized prototype is a 12 by 12 matrix to switch between different communication channels, employing electrostatic activated RF MEMS switches. The electrostatic switches are produced on Silicon in micromachining technology, they are easy to fabricate and offer nowadays a high reliability. The whole system consists of a packaged LTCC multilayered board, where Silicon-chips with the RF MEMS switches are integrated on one side, and a separate control electronic on the other side. Compared to the 12x12 switch matrix used on ARTES4/AMOS4 flexible telecom satellite (2013), the measured weight of the …
