摘要

采用集成无源器件（IPD）技术，提出了一种基于砷化镓衬底的低插入损耗紧凑型带通滤波器。该滤波器将并联电容器和接地电容器引入缠绕的螺旋电感结构。该滤波器基于缠绕式螺旋电感结构，通过加入接地电容实现低插入损耗和延长阻带。该滤波器的尺寸为0.011λ0 × 0.0082λ0，在中心频率为2.67 GHz时的插入损耗为0.73 dB，两个传输零点分别位于5.46 GHz和7.77 GHz，在4.62-8.28 GHz频率范围内实现了-20 dB的阻带。

A Low-Loss Bandpass Filter With Intertwined Spiral Inductor Using GaAs-IPD Technology

This paper presents a compact bandpass filter with low insertion loss based on a GaAs substrate, utilizing integrated passive device (IPD) technology. The filter introduces parallel and grounding capacitors to the intertwined spiral inductor structure. Based on the intertwined spiral inductor structure, the filter achieves low insertion loss and extends the stopband by incorporating grounded capacitors. The fabricated filter, with a size of 0.011λ₀ × 0.0082λ₀, achieves an insertion loss of 0.73 dB at a center frequency of 2.67 GHz, two transmission zeros are located at 5.46 GHz and 7.77 GHz, achieving a -20 dB stopband over the frequency range of 4.62–8.28 GHz.
