Abstract

The present contribution reports a systematic design methodology to develop a compact 5-pole Butterworth low-pass filter based on the concept of transverse resonance in the 0.15 µm gallium arsenide process. The reported transverse resonance low-pass filter (TR-LPF), in hybrid technology, at a cut-off frequency of 10.4 GHz, has an insertion loss of 0.5 dB and more than 25 dB return loss. The “C”-and “Z”-shaped folded stubs, loaded with additional shunt capacitors and spur resonators, provide compactness and wideband rejection bandwidth (RBW). The RBWs at 20, 30, 40, and 50 dB attenuation levels are 49.8, 40.5, 31.4, and 13.4 GHz. The size of the TR-LPF is approximately $0.11 λ_{g} \times 0.079 λ_{g}$ .

紧凑型宽抑制带宽低通滤波器0.15µm砷化镓工艺的系统设计

本文报告了一种基于0.15 μ m砷化镓工艺中横向共振概念的紧凑5极巴特沃斯低通滤波器的系统设计方法。据报道，采用混合技术的横向共振低通滤波器（TR-LPF），截止频率为10.4 GHz，插入损耗为0.5 dB，回波损耗大于25 dB。“C”形和“Z”形的折叠存根，装载了额外的分流电容器和杂散谐振器，提供了紧凑性和宽带抑制带宽（RBW）。20、30、40和50 dB衰减水平下的rbw分别为49.8、40.5、31.4和13.4 GHz。TR-LPF的尺寸约为0.11 λ g × 0.079 λ g$0.11{\lambda}_{g}\乘以0.079{\lambda}_{g}$。
