Abstract (en)
A tunable cavity filter is proposed. The tunable cavity filter comprises a housing which is made of metal forming a cavity. Inside the cavity, a tunable element is attached to one side of the cavity. The tunable element is expandable or compressible using a control voltage, thus, if a control voltage is applied the tunable element expands or compresses itself.
