一种GSM-R终端滤波器
摘要：
本发明公开了一种可以应用于列车自动防护设备（ATP）和机车综合无线通信设备（CIR）的GSM-R终端滤波器，所述GSM-R终端滤波器的带外信号抑制不小于35dB，所述GSM-R终端滤波器的插入损耗不大于6dB。本发明还提供了一种GSM-R终端滤波器，所述GSM-R终端滤波器的带外信号抑制不小于30dB，所述GSM-R终端滤波器的插入损耗不大于4dB。由于采用了上述参数的GSM-R终端滤波器，极大提高了GSM-R终端的通信质量。
摘要（英）：

The invention discloses a GSM-R terminal filter which can be applied to an automatic train protection (ATP) device and cab integrated radio communication equipment (CIR). The out-band signal curbing of GSM-R terminal filter is not smaller than 35dB, and the insertion loss of the GSM-R terminal filter is not larger than 6dB. The invention further provides another GSM-R terminal filter, wherein the out-band signal curbing of GSM-R terminal filter is not smaller than 30dB, and the insertion loss of the GSM-R terminal filter is not larger than4 dB. Therefore, the communication quality of a GSM-R terminal is greatly improved.
