摘要

提出并分析了一种基于混合吸收结构的准无反射滤波器（QRL）。该滤波器采用模块化设计理念，由具有频率互补性的传统滤波器组成的准互补双工器（QCD）网络和集成移相器和损耗功率合成器的反射-吸收补偿（RAC）网络组成。RAC网络的引入提高了QCD网络的无反射频率范围。这使得传统的互补带通和带阻滤波器能够快速转化为具有超宽带吸收能力的QRL滤波器，而无需严格的互补响应或指定的馈电结构设计。为了验证这一方法，采用GaAs集成无源器件（IPD）工艺，模拟并制作了由多模微带谐振器组成的24 - 28ghz准无反射带通滤波器（QRL-BPF）。测量结果表明，所提出的QRL-BPF实现了150%的无反射相对带宽（RFBW），反射吸收水平接近- 10dB。

Design of quasi-reflectionless filter based on hybrid absorption architecture

In this paper, a quasi-reflectionless (QRL) filter based on hybrid absorption architecture is proposed and analyzed. The filter adopts a modular design philosophy, comprising a quasi-complementary diplexer (QCD) network formed by conventional filters with frequency complementarity and a reflection-absorption compensation (RAC) network integrating phase shifters and lossy power combiners. The incorporation of the RAC network enhances the reflectionless frequency range of QCD network. This enables conventional complementary bandpass and bandstop filters to be rapidly transformed into QRL filters with ultra-wideband absorption capabilities, without strict complementary responses or designated feeding structure designs. To demonstrate this approach, a 24–28 GHz quasi-reflectionless bandpass filter (QRL-BPF) consisting of multi-mode microstrip resonators is simulated and fabricated using GaAs integrated passive device (IPD) process. Measured results show that the proposed QRL-BPF achieves a reflectionless relative bandwidth (RFBW) of 150 % with reflection absorption level approaching −10dB.
