Dimensional Synthesis for Wide-band Band- Pass Filters with Quarter-wavelength Res- Onators
This paper presents a dimensional synthesis method for designing wide-band quarter-wavelength resonator bandpass filters. In this synthesis method, an alternative lowpass prototype filter and the edge frequency mapping method are proposed and applied. The improved Kand J-inverter model with the exponent-weighted turns ratio is also proposed in order to incorporate the frequency dependence of in...
متن کاملCpw Bandpass Filters Using End - Coupled Quarter - Wavelength Resonators
Inductï ely and capacitï ely end-coupled quarter-wä elength-resonator bandpass CPW filters are introduced. For a gï en bandwidth and passband shape, the new filters ha ̈e a smaller size, wider upper stop band and looser coupling between resonators than end-coupled half-wa ̈elength-resonator CPW filters. The design of two filters with 5% and 50% bandwidth at 10 GHz is presented. Q 1997 John Wiley ...
متن کاملMicrostrip Bandpass Filters Based on Inductive-Coupled Stepped-Impedance Quarter-Wavelength Resonators
Inductive-coupling scheme for microstrip bandpass filters with quarter-wavelength steppedimpedance resonators is proposed. This is realized by a short-end stub which behaves as a K-inverter. It is investigated that the coupling coefficient of the resonators can be easily controlled by the length of the short-end stub. The filter has a compact size and good stopband rejection by employing the qu...
متن کاملCompact Dual-Band Bandpass Filter Based on Quarter Wavelength Stepped Impedance Resonators
This paper presents a compact dual-band bandpass filter that involves using the quarter wavelength stepped impedance resonators (SIRs) for achieving simultaneously compact circuit size and good dual-band performance. The filter is designed at 2.4 / 3.5 GHz and constructed by two pairs of quarter wavelength SIRs and source-load lines. By properly tuning the impedance ratio, length ratio and radi...
متن کاملSpurious Suppression Effect by Transmit Bandpass Filters with HTS Dual-Mode Resonators for 5 GHz Band
We report on the spurious suppression effect in lowmicrowave power transmitters by high temperature superconducting (HTS) bandpass filters (BPFs) which are promising for devices requiring BPFs with high-frequency selectivity. Some of the major issues on the power BPFs with HTS planar circuits for wireless communication applications are reviewed. As a case study for the HTS filter and its spurio...
