Abstract:
A high-frequency switch in which external conductors and a central conductor are provided on a substrate, the external conductors and the central conductor constituting a coplanar high-frequency wave line on the substrate, the high-frequency switch including:a deflectable air-bridge held on the external conductors via an air gap and extending out over the central conductor, the air-bridge being deflectable by an electrostatic field created by an actuation voltage applied between the wave line and the air-bridge; anda control-signal conductor for generating the actuation voltage between the wave line and the air-bridge;wherein the central conductor acts as the control-signal conductor which generates the actuation voltage between the wave line and the air-bridge,wherein the air-bridge contains a plurality of laminated thin films, the laminated thin films having variable internal stresses that are adjustable to match a particular actuation voltage selected for the switch.
