Digital Broadband MMDS Transmitter

1.Ultra-linear power amplifier design
2.Low non-linear distortion
3.Ultra-low local oscillator phase noise

 

  We are a high technology enterprise which integrates the research, manufacture, sales and service of digital CATV products. And we have experience in providing total solutions of DVB-S,DVB-T and DVB-C systems.We can design,manufacture and debug.If you need the sort of the products,pls feel free to contact us.

 

Feature:

The main feature of this system is that detect the state of outdoor transmitter by GSM any time, such as working voltage, transmitting power, working temperature, etc. It’s not only change the situation that can’t check the outdoor transmitter state, but also save much cost for maintenance.

Comprehensive self-diagnostic, protection function, the user can monitor the working status timely.

Ultra-low local oscillator phase noise, ensure high-quality digital signals transmission.

Compatible with different of digital modulations.

Ultra-linear power amplifier design, low non-linear distortion, transmission power upgraded, ensuring high-quality signals for remote users.

Modular design for easy maintenance and replacement.
