Wide-band frequency Transmission Network Technology is an innovative technology using one Wide-band frequency transmitter to achieve multi-channel transmitting, solving the existing problems of single-channel system in one fell swoop. It is conducive to build up the terrestrial digital tv multi-channel single frequency network with effective coverage and strong stability.

Wide-band frequency transmission network technology has been successfully applied in China, its advent lies in:

1). The signal using the low power multiplex approach before delivered to transmitter, it can generate a number of adjacent frequency (or repeat frequency) RF signals. In the multi-channel single frequency networking stage, the entire network can share the same exciter, so that the system RF signal can reach to a high level of consistency, without the excursion of frequency, phase, level, etc. it is conducive to build the multi-channel single frequency network.

2). With the highly coherent RF signal source, conducive to the full play of Wide-band frequency RF delay technology, it brings the new model of single frequency networking.

3). Wide-band frequency networking technology solution can save the cost of multiplexer, increase the efficiency and quality of multiple frequency synthesis.

4). Cast aside the power combiner of the traditional transmitting system, dramatically reduce the insertion loss in system connection, it can significantly reduce the transmission power meantime ensuring the equal coverage effect. Saving the investment and operating cost, it is conducive to the industry healthy development.

5). Thoroughly avoid the signal interference between channels caused by the frequency shift between spectrum when the multi-channel high-power combiner output.
