Abstract

A compact bandpass filter (BPF) has been developed and fabricated using high-resistivity silicon (HRS) integrated passive device (IPD) technology. The core component of the BPF is designed with a source-load coupling network, which facilitates the generation of transmission zeros on both sides of the passband. To improve high-frequency stopband rejection and ensure impedance matching between the source-load coupling network and the load, a cascaded lumped Pi-type network has been integrated into the design. The layout of the design employs high-Q tapered spiral inductors, which are utilized to minimize insertion loss. To evaluate the performance of the design, an on-chip filter operating within the 5G N77 band has been fabricated, achieving compact dimensions of 1 × 0.5 mm². Measurement results indicate that the BPF attains an N77 in-band insertion loss of less than 1.7 dB and a 3-dB fractional bandwidth exceeding 61.3 %, along with an out-of-band rejection of 23.4 dB at the LTE band 3 uplink frequency.

紧凑型HRS IPD N77带通滤波器基于锥形螺旋电感和创新的源负载耦合

采用高阻硅（HRS）集成无源器件（IPD）技术研制了一种紧凑型带通滤波器（BPF）。BPF的核心组件采用源负载耦合网络设计，便于在通带两侧产生传输零点。为了提高高频阻带抑制能力，确保源负载耦合网络与负载之间的阻抗匹配，在设计中集成了级联的集总pi型网络。设计的布局采用高q锥形螺旋电感，利用它来最小化插入损耗。为了评估该设计的性能，已经制造了一个在5G N77频段内工作的片上滤波器，实现了1 × 0.5 mm2的紧凑尺寸。测量结果表明，BPF在LTE波段3上行频率下的N77带内插入损耗小于1.7 dB， 3db分数带宽超过61.3%，带外抑制为23.4 dB。
