Trunk Amplifier

1.Trunk amplifier also maned cable amplifier is mainly used to compensate for power loss caused by signal transmission and distribution in passive indoor distribution system.

2.Trunk amplifier is an active device. In indoor distribution system using trunk amplifier, it is necessary to consider the influence of noise figure of trunk amplifier on downlink sensitivity of distribution system and noise elevation on upstream of whole distribution system.

3.The upstream and downstream gain regulation of dry amplifier should not only ensure that the upstream gain can not affect the system performance too high, but also ensure the effective transmit power of the antenna port of the amplifier branch, and pay attention to the appropriate upstream and downstream gain regulation to ensure the upstream and downstream balance.
