摘要
介绍了基于玻璃集成无源器件(IPD)技术的5G新无线电(NR) n77和n79频段带通滤波器设计。n77滤波器在3.3 ~ 4.2 GHz频段的通带损耗仅为1.4dB，在2.69和5.15 GHz频段的衰减为30dB。n79滤波器在4.4 ~ 5.0 GHz频段的通带损耗为2.0 dB，在2.69 GHz频段衰减为35 dB，在5.49 GHz频段衰减为17 dB。两种滤波器的XY尺寸均为2.0 mm x 1.25 mm，与现有的LTCC解决方案相同，但IPD滤波器厚度仅为0.3 mm，有利于RF前端模块(FEM)中的滤波器集成。
Design and Fabrication of Band-Pass Filter on Glass IPD for 5G New Radio
Band pass filter design based on glass integrated passive device (IPD) technology for n77 and n79 bands in 5G new radio (NR) is demonstrated in this paper. The pass band loss for n77 filter is only 1.4dB from 3.3 to 4.2 GHz, and the attenuation at 2.69 and 5.15 GHz is 30dB. For n79 filter, the pass band loss is 2.0 dB from 4.4 to 5.0 GHz, and the attenuation is 35 dB at 2.69 GHz and 17 dB at 5.49 GHz. The XY dimension for both filters is 2.0 mm x 1.25 mm which is the same as existing LTCC solution, but the IPD filter thickness is only 0.3 mm that is advantageous to filter integration in RF front-end module (FEM).
