发夹梳状滤波器中的折叠半波长谐振器都具有相同的取向，而传统发夹滤波器中的谐振器的取向是交替的。发夹梳状滤波器被证明具有有吸引力的性能，紧凑的设计，窄带滤波器，如通常需要的高温超导（HTS）和其他应用。从两个和四个谐振器试验高温超导滤波器设计的结果进行了讨论。滤波器被认为具有非常强的阻带，其计算和测量的性能被发现是在非常好的协议。
The folded half-wavelength resonators in hairpin-comb filters all have the same orientation, whereas the orientations of the resonators in conventional hairpin-filters alternates. Hairpin-comb filters are shown to have attractive properties for design of compact, narrow-band filters such as are often desired for high-temperature-superconductivity (HTS) and other applications. The results obtained from two- and four-resonator trial HTS-filter designs are discussed. The filters are seen to have very strong stopbands, and their computed and measured performance are found to be in very good agreement.
