WWK Alpha+ Digital channel amplifier
WWK ALPHA+ is a new generation, digital selective amplifier. Designed and produced by TELKOM-TELMOR based on the brand new technologies to offer:
- high selectivity + 32 filters
- high gain + AGC
- protection from unwanted signals (LTE, 5G)
- best possible output signals, no unwanted signals
This device will be the best choice as a first active device in terrestrial television signal distribution network and other signals (e.g. using ports AUX, DAB*, FM).
Offers adjustable output level from 98 to 118 dBμV + possible equalization.
Each DVB-T/T2 signal can be configured separately according to input and desired output frequency as well as output level. Additionally, it is also possible to check the output power level at selected frequencies (dynamic measurement). Installation and parameter adjustment are done by local manipulator and are visible on large display VFD (2x16 characters).
We also have the option of filtering LTE channels from the 700 and 800 MHz bands and the ability to power antenna preamplifiers connected to the ports (VHF / UHF 1..4).
Test point with 30dB attenuation will allow you to use it for measurements on simple meters or for connecting the signal to optical distribution systems without additional accessories in the form of attenuators.
The narrow housing and external power supply allow the device to be placed in all kind of mounting cabinet.
