Abstract
An embodiment radio frequency MicroElectroMechanical (RF-MEMS) tunable bandpass filter includes one or more tunable resonators, each of which includes an electrically reconfigurable capacitor bank, a tuning screw, and a resonating structure. In an embodiment, the capacitor bank includes fixed value capacitors and switches to vary the capacitance of the resonator. In an embodiment, the capacitor bank includes variable capacitors and direct current (DC) bias circuits to vary the capacitance of the resonator. The filter may be incorporated into a time division duplexing (TDD) base station or other wireless communications device.
