TVS-104 Head-end Upgrade Filter Device


* A device is intended for summation of the channels combined into groups from the   head-end outputs.
* The device is constructed on the basis of filters
* The device enables the signal-to-noise ratio rise in each channel without alteration in   the head-end in which signal summation occurs at directional couplers. The signal-   to-noise ratio is raised while reducing the noise added from other channels. The   device enables reducing out-of-band unwanted spectrum components
* Input-output transmission gain spread is not higher than ±1dB. It preserves the range   of each channel output level control (of a channel group) of the head-end
* A customer defines channel groups
