摘要
根据低温共烧陶瓷技术的特点,提出了一种二阶微波带通滤波器的三维结构设计方法,设计的滤波器结构简单、尺寸小、工作频率可调。按照该设计方法,通过电磁仿真软件AnsoftHFSS10设计了一款带通滤波器。结果表明,该滤波器的中心频率为5.2GHz,带宽为0.4GHz,通带内插损小于2.1dB,尺寸为2.5mm×2.2mm×0.4mm,能够满足微波无线通信系统的要求。
According to LTCC technology characteristics, an effective design method for the three-dimensional structure of a two-order LTCC microwave band-pass filter was proposed. The filter has merits such as design simple and small in structure, and work frequency is adjustable. According to the design method, a microwave band-pass filter with center frequency 5.2 GHz and bandwidth 0.4 GHz was designed by using Ansoft HFSS 10 simulating soft ware. The simulation results show that the insertion loss of the filter is less than 2.1 dB, with the size of 2.5 mm×2.2 mm×0.4 mm, the filter meets the need of microwave wireless communications systems.
