Description
（1）Filter Modules：Filter the sideband signal, only take the
actual signal and send it to the power amplifier.
（2）AGC Amplifier Module：the module is make up of IF
amplification and AGC decay control.
（3）Promote Power Amplifier
Modules:Â the
module can amplify filtered signal. It is composed from 5 amplifier
pipes and has power detector and current detection.Â
（4）Aftermost Amplifier Module：It is adopt balance amplifier program to
improve reliability. Each channel has separate power supply and
temperature protection. The module has power detector current
detection. The power supply voltage is **8 V.
（5）According to the installation and use of the equipment, the
end output will equip more high-power cavity filters.
