Description

The WWK-ALPHA-2 is an advanced digital multi-band amplifier designed for professional SMATV antenna installations and extensive individual systems. The device is a key component of television infrastructure, enabling precise and selective processing of DVB-T/T2 signals in the VHF and UHF bands. Thanks to the use of a modern DSP platform, the amplifier offers the user a range of benefits, such as the ability to integrate DAB and FM signals, as well as flexibility in working with external modulators and headends via a dedicated AUX input. The main advantage of the device is the precise level adjustment of each multiplex, which allows for perfect signal balancing throughout the installation. The channel conversion function within the band and Automatic Gain Control (AGC) guarantee reception stability even in difficult signal conditions. The amplifier is characterised by high resistance to intermodulation distortion, which translates into a clean and clear image. An additional advantage is the built-in advanced LTE 700 / LTE 800 filter, including a specialised SAW filter for the 700 band, which effectively eliminates interference from LTE/5G mobile networks. The device is intuitive to operate thanks to a large LCD display and quick-access buttons, which significantly reduces installation configuration time.

Software and interface

The device has a built-in management system based on a DSP platform, operated via a built-in LCD display and quick-access buttons. The software allows for full configuration of gain parameters for each multiplex individually, which allows for precise alignment of signal levels in the installation. The system supports an automatic channel scanning function, which significantly speeds up the installation commissioning process. The software also manages intelligent antenna preamplifier power supply, monitoring current consumption and protecting the installation against overload. The user interface is designed to be clear, allowing for a quick overview of operating parameters such as signal level, frequency, and LTE/5G filter status. Thanks to digital signal processing, the software ensures high operational stability and resistance to interference, offering advanced diagnostic functions necessary in professional SMATV systems.
