| 发明名称 | Wideband electronically tunable cavity filters | ||
| 摘要 | An apparatus to filter electromagnetic waves includes a cavity and one or more tuning circuits. The cavity is configured to receive the electromagnetic waves and has a resonant frequency. The one or more tuning circuits are disposed proximate to or in the cavity. The one or more tuning circuits and the cavity are configured to filter the electromagnetic waves and the resonant frequency of the cavity is based on the one or more tuning circuits. | ||
