KC9480系列带限幅功能偏直器

kcma2022/11/03 15:54:22科创仪表 IP:四川

KC9480是用于馈线供电的直流偏置器，可配合KC9605系列馈线供电放大器使用。

序号	型号	频率下限	频率上限	损耗	耐压	备注
01	KC9480	1MHz	6GHz	1dB	30V	量产
02	KC9480B	1MHz	18GHz	2dB	30V	预发布

*损耗是典型值。由于配合前置放大器使用，故插入损耗是不重要的，只要不太大，不影响接收灵敏度。

插损抽样实测：

回损抽样实测。由于内有限幅器，回损一般，但基于应用场景，不会产生不良影响。

KC9480内置限幅器，可将通过功率压缩至通常不超过20dBm，避免近处的意外发射烧毁后续的接收机等信号用户。使用时应注意正常的输入功率不宜超过10dBm，避免使限幅器经常承受功率。

该装置的ESD承受能力是CLASS 1C。在有雷击风险的地方使用，应在前方安装避雷器，所用避雷器应能承受偏直器所提供的直流电压。避雷器放电时，偏直器的直流会被避雷器短路且无法灭弧，直到内部保险丝熔断，如遇这种情况，需返厂修理。

为了适应不同的应用场景，KC9480有两个电源输入口，只需使用其中一个即可，但也可以同时使用两个，以提供冗余。

KC9480适合在机房或防水机柜中使用，本身不具备防水能力。请留意只有KC9605系列放大器具有防水能力，放大器可以放置于室外，而为它供电的偏直器应当放置于防潮、防雨的场所。

KC9480的机械尺寸如下：

生产状态：量产
