Enabling of Embedded RF-MEMS Microwave Integrated Circuit Process for Space Applications


  • Pre-evaluation of the reliability for embedded RF-MEMS switches
  • Reliability tests with respect to space qualifications tests (step stress tests, thermal storage, endurance tests, environmental tests)

IHP's Contribution

  • Development of 50 GHz RF-MEMS switch for space applications
  • Provide chipsets to project partners for extensive reliability tests


  • RF-MEMS switches are advantages over their semiconductor competitors like PIN diodes or FET transistors due to their low insertion loss and high isolation, high linearity and nearly zero power consumption;
  • Monolithic integration of RF-MEMS in a BiCMOS technology provides the possibility to achieve very highperformance chipsets due to the non-existing parasitics of packaging and the high level of integration;
  • Reliability is still one of the main concerns for the operation of RF-MEMS switches especially for space applications.


This project has received funding from the European Space Agency under contract Nº 4000112274/14/NL/RA.
