Smart MEMS concept for RF and millimeterwave communications

This paper outlines the Microsystem concept for the next communications systems. Among the results, we can note that the use of hetero-junction concept in silicon bipolar transistor translates into operating frequencies higher than 100 GHz. Moreover, the MEMS concept leads to very low loss passive circuits useable up to millimeterwave and having the ability of agility. Furthermore, these technologies are becoming to be involved in the realization of smart microsystems for millimeter-wave applications like reconfigurable frond end.
