Product Description
The Structure of Transmitter:
(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: The module can amplify filtered signal. It is composed from 5 amplifier pipes and has power detector and current detection.
(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 +48 V.
(5)According to the installation and use of the equipment, the end output will equip more high-power cavity filters.
Performance:
A. Through information transmitting cable, this system can connect the indoor controlling equipment and outdoor controlling equipment, and can monitor the indoor working conditions, such as voltage, transmitting power, temperature, etc, and also can adjust the indoor transmitting power and clear the alarms through touch screen.
B. Perfect self-diagnosis and protection features, users can timely monitor the working state.
C. The low-phase noise, ensure high-quality digital signal transmission
D. Compatible with a variety of digital modulation.
