| 摘 要： | 采用低温共烧陶瓷(low temperature co-fired ceramics,LTCC)集成技术研制出小型的抗电磁干扰(EMI)滤波器,同时通过在滤波器带外引进一传输零点,增加了滤波器的带外陡度。结果表明:该滤波器的截止频率为84 MHz(3dB),带外抑制≥30 dB(250~2 500 MHz),达到设计要求。其外形尺寸为2.00 mm×1.25 mm×0.80 mm,远小于传统的同类型滤波器。

| Abstract: | A miniaturized anti-electro magnetic interference filter was developed based on the technology of LTCC,and increased the filter gradient of the band out by adding a transmission zero point at the band out.Results show that the filter with center frequency 84 MHz(3 dB) and attenuation ≥30 dB(at 250~2 500 MHz),arrives designed asks.The form dimensions are 2.00 mm×1.25 mm×0.80 mm,much less than same style traditional filters. |
