Filtr to LBQ-150-4 <\/a>
\nFiltr 4 komorowy mo\u017cna zam\u00f3wi\u0107 w r\u00f3\u017cnych szeroko\u015bciach pasma przepustowego od +\/-\u00a0 0.5MHz do 4MHz. Ja zam\u00f3wi\u0142em +\/- 1MHz.<\/p>\n

Filtr jest ma\u0142y – 10cm x 10cm x 3cm ja zam\u00f3wi\u0142em z gniazdami SMA, ale s\u0105 dost\u0119pne r\u00f3wnie\u017c wersje z N czy BNC. Wa\u017cy oko\u0142o kg.
