Abstract

This letter proposes a wideband high selective on-chip bandpass filter (BPF) implemented on GaAs substrate integrated passive device (IPD) technology. Introducing lumped elements outside the resonator and coupling them with the resonator can introduce three transmission zeros (TZs). These three TZs are elaborately generated to enhance frequency selectivity and improve stopband rejection level. Moreover, it leverages high-quality-factor lumped elements, significantly bolstering the circuit’s resonance capacity. When wideband performance is necessary, using the Chebyshev principle for design allows achieving the desired bandwidth. To validate this design approach, a BPF centered at 3.8 GHz was simulated, fabricated and measured using GaAs IPD technology, showing promising applications in integrated circuit designs.
具有高频选择性的GaAs IPD技术中的宽带片上带通滤波器
本文提出了一种基于砷化镓衬底集成无源器件(IPD)技术的宽带高选择性片上带通滤波器(BPF)。在谐振腔外引入集总元件并与谐振腔耦合可引入三个传输零点。这三个TZs是精心产生的,以提高频率选择性和提高阻带抑制水平。此外,它利用高质量因子集总元件,显著增强了电路的谐振能力。当需要宽带性能时,使用切比雪夫原理进行设计可以实现所需的带宽。为了验证这种设计方法,利用GaAs IPD技术模拟、制造和测量了一个以3.8 GHz为中心的BPF,显示出在集成电路设计中的良好应用前景。
