LNB LNB 百科解释 LNB又叫高频头(Low Noise Block)即低噪声下变频器,其功能是将由馈源传送的卫星信号经过放大和下变频,把Ku或C波段信号变成L波段,经同轴电缆传送给卫星接收机。 通信词典解释
Lyons Bancorp, Inc., the parent financial holding company of The Lyons National Bank (LNB), reported earnings of $15.5 million for 2024, down approximately 11% from LNB’s record earnings of $17.4 million in 2023. On a per share basis, earnings were $4.38 as compared to $4.90 last year...
LNB又叫高频头,是低讯降频放大器,即低噪声下变频器,它由LNB与LNC组成,LNC则由混频器本机振荡器构成,LNB一般可分为c频lnb和ku频LNB,其功能是将由馈源传送的卫星信号经过放大和下变频,把ku或c波段信号变成L波段,经同轴电缆传送给卫星接收机,LNB因卫星讯号在抵达天线前,已相当微弱及同轴电缆传送的频率越高讯号损耗...

1 LNB又叫高频头（Low Noise Block），即低噪声下变频器，其功能是将由馈源传送的卫星信号经过放大和下变频，把Ku或C波段信号变成L波段，经同轴电缆传送给卫星接收机。LNB（low noise block downconverter）就是低讯降频放大器，它由LNB与LNC组成，LNC则由混频器、本机振荡器构成。LNB一般可分为c频lnb（3.7GHz...
卫星高频头（LNB）的几个基本参数 一、输入频率（INPUT） 1、C波段a、3.4—4.2G；b、3.7—4.2G； a比b频率范围宽，a应优先选用 2、Ku波段：全波段为10.7GHz——12.75GHz；其低频段为10.7GHz—11.8GHz、高频段为11.7GHz—12.75GHz。而低频段为10.7GHz—11.8GHz应配合低本振9.75GHz使用 二...
