给出了多种微型半波多锯齿谐振器，并利用这些谐振器开发了无交叉线的八极高温超导（HTSC）准椭圆滤波器。本文还提出了一种新颖的单极点群延迟均衡器来平坦化非线性相位准椭圆滤波器的相位，解决了HTSC线性相位滤波器的调谐困难。而且，不仅可以保证成品HTSC滤波器具有良好的线性相位特性，而且还解决了线性相位滤波器与外部均衡的集成。最后，在尺寸为31.6 mm×29.2 mm的YBCO/LaAlO3/YBCO衬底上，研制了一种采用外均衡的微型八极HTSC准椭圆线性相位滤波器，其中心频率为2250.84 MHz，带宽为14 MHz，通带内最佳插入损耗为2.09 dB，回波损耗优于18.97 dB。测量。在通带内，测量的群延迟响应与仿真响应具有良好的一致性，并且在 78.5% 的滤波器带宽内其变化小于 50 ns。
A variety of miniature half-wave multizigzag resonators was given, and an eight-pole high-temperature superconductor (HTSC) quasi-elliptic filter with no cross-line was developed with these resonators. In this paper, a novel single-pole group delay equalizer was also given to flatten a nonlinear phase quasi-elliptic filter's phase, which solves the tuning difficulty of the HTSC linear phase filter. Moreover, it cannot only ensure that the finished HTSC filter has a good linear phase characteristic but also solve the integration of the linear phase filter with external equalization. Finally, on YBCO/LaAlO3/YBCO substrate with the dimension of 31.6 mm × 29.2 mm, a miniature eight-pole HTSC quasi-elliptic linear phase filter using external equalization is developed, where the center frequency is 2250.84 MHz, the bandwidth is 14 MHz, the best insertion loss in passband is 2.09 dB, and the return loss is better than 18.97 dB, as per measurements. In passband, the measured group delay response has a good agreement with the simulated response, and its variation is less than 50 ns over 78.5% of the filter bandwidth.
