abstract = {The paper reviews the developments made for designing and
fabricating a piezoelectric driven actuator and its
integration into coplanar wave guide (CPW) microwave
structures. In the first part of this work the
electromechanical properties of different
lead–zirconate–titanate (PZT) thin films are
investigated. A modified precursor route for chemical
solution deposition (CSD) is introduced to minimize the
thermal budget of the PZT by maintaining its superior
piezoelectric properties. The second part deals with the
fabrication of a piezoelectric driven actuator for use in RF
switching applications. Advantages of bulk and surface
micromachined devices are compared and a suitable actuator
design is proposed. Based on these results, a
piezoelectrically actuated shunt switch for use in CPW
devices is developed and optimized, and the concept is
confirmed by measurements. Finally, novel reconfigurable CPW
band-pass filters are presented, which demonstrate the
usefulness of the developed shunt switches in microwave
applications.},
