一种S波段LTCC带通滤波器的改进设计
Improved design of a S-band LTCC band-pass filter
摘要
Abstract
The new minitype band-pass filter (BPF) fabricated by low-temperature cofired ceramics (LTCC) was designed.The circuit of this filter was composed of 2-orders resonant cavity by capacitive coupling.The three-dimensional multi-layer structure of this filter was designed,and the adding of a transmission zero improved the performance of this filter.The simulating results show that the center frequency of this filter is 3.41 GHz,and its relative bandwidth is 5.9%(200 MHz).It has a wide range of application in S-band of communication system and other RF systems with its size of only 3.8 mm × 2.8 mm × 0.8 mm.关键词
