Abstract

This letter presents a compact dual-band filtering power divider (DBFPD) based on a novel dual-

$\pi $

-type matching circuit (MC). The proposed dual-

$\pi $

-type MC achieves precise dual-band matching through analytical design, and integrated hybrid resonators (HRs) significantly enhance the bandwidth of passbands. Three independently controllable transmission zeros (TZs) of DBFPD improve stopband rejection and frequency selectivity. To validate the design, a DBFPD working at 8.9 and 21.6 GHz with a compact size of

$1.9\times 3.1$

mm² is fabricated and measured using integrated passive device (IPD). The design achieves low insertion loss (IL) and wide bandwidth, with minimum ILs of 0.43 and 0.47 dB and 3-dB bandwidths of 50% and 33.5%, respectively.

一种新型的基于ipd的x波段和k波段双频滤波功率分压器芯片

本文介绍了一种基于新型双$\pi $型匹配电路（MC）的紧凑型双带滤波功率分配器（DBFPD）。所提出的双$\pi $型MC通过分析设计实现了精确的双带匹配，集成的混合谐振器（hr）显著提高了通带带宽。DBFPD的三个独立可控传输零点（TZs）提高了阻带抑制和频率选择性。为了验证该设计，制作了一个工作在8.9和21.6 GHz的DBFPD，其紧凑尺寸为1.9\ × 3.1$ mm2，并使用集成无源器件（IPD）进行了测量。该设计实现了低插入损耗和宽带宽，最小插入损耗分别为0.43和0.47 dB， 3db带宽分别为50%和33.5%。
