摘要：A class of RF multi-functional band pass filter with multiple frequency reconfigurable rejected bands that are embedded into its broad transmission frequency range is reported. The proposed setup consists of a rectifying circuit fed by the reject band output port of a planar directional filter, using a micro strip resonator as the matching network. This filter concept exploits an original tunable multi-band quasi band stop section as constituent block. It allows obtaining unprecedented level of spectral adaptively for its in-band notches the overall reflection to be suppressed without affecting the pass band channel. These notches can be either used to increase the number of rejected bands or their selectivity by respectively locating them at identical or different center frequencies.
