Classes of bandpass filters having an arbitrary wide stopband and design tables for one such class

Several filter classes that can be used to obtain a bandpass filter with an arbitrary stopband width are defined. These filters have the advantage that they are physically very small because the quarter-wave frequency is situated much higher than the center frequency. Design tables for relative bandwidths of 90 and 100% are given, and measured results for a stripline filter without chip capacitors are presented.<
