Detailed
Main Features
470~862MHz broadband response and low noise design Design of low power consumption and linearization advances emitting power of the transmitter and reduces nonlinear distortion. Very low group delay feature suitable for digital signal transmission ALC keeps output of constant power，output VSWR detecting protection Apply to single channel or multichannel UHF digital TV transmission system Be used in the broadband repeating of HFC、AML or MMDS digital TV signal Realize wireless network coverage of digital TV at a low cost Modular design simplifies installation, field service and upgrade. Automatic and manual back-up systems available Redundant design of the power supply improve reliability of the equipment. Build-in lightning protector with current-dividing series power prevents lighting surge and instant overvoltage Local monitoring and control Remote monitoring and control(Optional) |
