摘要

提出了一种尺寸紧凑、选择性高的低温共烧陶瓷(LTCC)双频带通滤波器。通过使用一组阶跃阻抗谐振器(SIRs)，实现了2.45/5.2GHz双频滤波器。一种新的源负载耦合诱导产生三个传输零点(TZs)，从而产生高选择性。电路尺寸为2.8 mm×2.5 mm×0.8 mm。给出了滤波器响应来验证理论预测。

Compact LTCC dual-band bandpass filter using stepped impedance resonators

This paper presents a low-temperature co-fired ceramic (LTCC) dual-band bandpass filter with compact size and high selectivity. By using one set of stepped impedance resonators (SIRs), a 2.45/5.2GHz dual band filter is achieved. A novel source-load coupling is induced to generate three transmission zeros (TZs), resulting in high selectivity. The circuit size is 2.8 mm×2.5 mm×0.8 mm. The filter responses are presented to verify the theoretical predications.
