Compact sext-band bandpass filter based on stepped-impedance resonators is presented. Two types of rejection responses beside passbands can be designed by I/O gap capacitance. Considering design freedom and circuit complexity, each pair of resonators determine respective channel characteristics. The proposed sext-band filters occupy an extremely small area of 0.26λg × 0.15λg as well as keep good selectivity among channels.
