Therefore, the higher the out-band rejection is the closer it is to the working frequency band, the better.\u003c\/p\u003e\n\u003cp\u003eA filter without marking this parameter is no different from cheating； Even if it should not be called a filter, it should be a transmission line（about zero insertion loss）......\u003c\/p\u003e\n\u003cp\u003eAbout Connections\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e1、There is no difference between the two RF ports of the filter. Both sides can be connected to the antenna or miner.\u003c\/p\u003e\n\u003cp\u003e2、The filter is connected between the antenna and the miner, or between the antenna and extender.\u003c\/p\u003e\n\u003ch3\u003eDESCRIPTION\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe 868MHz Cavity Filter operates from 863-870MHz with a 7MHz bandpass and uses for Helium Networks.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis component has ultra-low insertion loss and good out-of-band suppression at 10MHz from a distance of side frequency. The 868MHz Cavity Filter features rugged aluminum construction and is for use indoors. The 868MHz Cavity Filter has N female connectors on both sides.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e863-870MHz Full Band LoRa Applications\u003c\/li\u003e\n\u003cli\u003eReduce Interference Outside the ISM Band and Improve Performance\u003c\/li\u003e\n\u003cli\u003eUltra Low Insertion Loss (1.0dB nominal)\u003c\/li\u003e\n\u003cli\u003eSuitable for work in Helium network and 868MHz LoRa IOT network\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSPECIFICATION\u003c\/h3\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/Sce7bdc6153574e97a4eb0919359859e0f.png\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 data-spm-anchor-id=\"a2g0o.detail.1000023.i1.4292f2b3I971jN\"\u003e\u003cstrong\u003eINCLUDED\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp data-spm-anchor-id=\"a2g0o.detail.1000023.i1.4292f2b3I971jN\"\u003e1* PCS of Cavity Filter\u003c\/p\u003e\n\u003cco-div class=\"trans-ext\"\u003e\u003cco-div class=\"trans-ext__trans-btn\" style=\"top: 180px; left: 313px;\"\u003e\u003c\/co-div\u003e \u003cco-div class=\"trans-ext__popup-arrow\" style=\"display: none;\"\u003e \u003cco-div\u003e\u003c\/co-div\u003e \u003cco-div\u003e\u003c\/co-div\u003e \u003c\/co-div\u003e \u003cco-div class=\"trans-ext__popup\" style=\"display: none;\"\u003e \u003cco-div class=\"trans-ext__title-bar\"\u003e \u003cco-div class=\"trans-ext__title-center\"\u003e \u003cco-i class=\"co-iconfont co-icon-sogou trans-ext__tool active\" data-trans-tool=\"sogou\" title=\"搜狗翻译\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-baidu trans-ext__tool\" data-trans-tool=\"baidu\" title=\"百度翻译\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-youdao trans-ext__tool\" data-trans-tool=\"youdao\" title=\"有道翻译\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-kingsoft trans-ext__tool\" data-trans-tool=\"kingsoft\" title=\"金山词霸\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-google1 trans-ext__tool\" data-trans-tool=\"google\" title=\"谷歌翻译\"\u003e\u003c\/co-i\u003e \u003c\/co-div\u003e \u003cco-div class=\"trans-ext__title-right\"\u003e \u003cco-i class=\"co-iconfont co-icon-zhankai1 trans-ext__tool-down\" title=\"显示更多\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-shouqi trans-ext__tool-up\" title=\"收起更多\" style=\"display: none;\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-xiangyoujiantou trans-ext__tool-right\" title=\"固定到右边\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-xiangzuojiantou-copy trans-ext__tool-left\" title=\"固定到左边\" style=\"display: none;\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-suoxiao1 trans-ext__tool-position\" title=\"取消固定\" style=\"display: none;\"\u003e\u003c\/co-i\u003e \u003cco-i class=\"co-iconfont co-icon-guanbi trans-ext__tool-close\" title=\"关闭\"\u003e\u003c\/co-i\u003e \u003c\/co-div\u003e \u003c\/co-div\u003e \u003ciframe class=\"trans-ext__iframe\" style=\"pointer-events: auto;\"\u003e\u003c\/iframe\u003e \u003c\/co-div\u003e \u003c\/co-div\u003e","brand":"ACASOM","offers":[{"title":"Default Title","offer_id":46102472130852,"sku":"","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/4330\/1668\/files\/1-main-868mhz-cavity-filter-for-helium-network-amplifier-filter-high-out-band-rejection.png?v=1692603507","url":"https:\/\/rf3c.com\/products\/868mhz-cavity-filter-for-helium-network-amplifier-filter-high-out-band-rejection","provider":"acasom","version":"1.0","type":"link"}
