New band-pass filter design with tapped-line using J/K-inverter

In this letter, a novel design method of tapped‐line gap‐coupled half‐wavelength band‐pass filter (BPF) using J‐ or K‐inverter is proposed. A model of tapped‐line is composed of shunt stub and the additional transmission line that has the electrical length of the negative value. The electrical lengt...

Zusammenfassung:In this letter, a novel design method of tapped‐line gap‐coupled half‐wavelength band‐pass filter (BPF) using J‐ or K‐inverter is proposed. A model of tapped‐line is composed of shunt stub and the additional transmission line that has the electrical length of the negative value. The electrical lengths of the stub and line are functions of the line's impedance and the inverter that has a variable of filter's bandwidth. © 2007 Wiley Periodicals, Inc.
