Abstract:
A tunable notch filter comprising a transmission line, a tunable bandstop filter and a tunable bandpass filter. The transmission line has an input port, an output port and a length electrically connecting the input port to the output port and receiving an RF signal at the input port. The tunable bandstop filter comprises a first direct current voltage source, a first coupling line and a first tunable capacitor. The first direct current voltage source provides a first adjustable voltage to the first tunable capacitor. The first tunable capacitor adjusts its capacitance based on the first adjustable voltage. The tunable bandpass filter comprises a second direct current voltage source, a second coupling line and a second tunable capacitor. The second direct current voltage source provides a second adjustable voltage to second tunable capacitor. The second tunable capacitor adjusts its capacitance based on the second adjustable voltage.

Claim (Index 8):
A filtering method comprising:\n providing an RF input signal to a tunable filter having:\n a transmission line having an input port, an output port and a length electrically connecting the input port to the output port, the transmission line being operable to receive the RF signal at the input port, the length having a first portion, a second portion and a third portion, the second portion being disposed between the first portion and the third portion; \n a tunable bandstop filter comprising a first direct current voltage source, a first coupling line and a first tunable capacitor, the first direct current voltage source being operable to provide a first adjustable voltage to the first tunable capacitor, the first tunable capacitor being operable to adjust its capacitance based on the first adjustable voltage; and \n a tunable bandpass filter comprising a second direct current voltage source, a second coupling line and a second tunable capacitor, the second direct current voltage source being operable to provide a second adjustable voltage to second tunable capacitor, the second tunable capacitor being operable to adjust its capacitance based on the second adjustable voltage; and \n outputting a filtered signal, wherein the tunable bandpass filter and the transmission line are arranged such that the second coupling line is operable to couple a first portion of the RF signal from the first portion of the length and such that the first portion of the length transmits a second portion of the RF signal to the second portion of the length, wherein the tunable bandstop filter and the transmission line are arranged such that the first coupling line is operable to couple, to ground, a third portion of the RF signal as provided by the first portion of the length line at the second portion of the length and such that the second portion of the length transmits a fourth portion of the RF signal to the third portion of the length, wherein the tunable bandpass filter and the transmission line are further arranged such that the second coupling line is further operable to couple a passed portion of the first portion of the RF signal to the third portion of the length.
