WWK ALPHA 2 Digital Multi-Band Amplifier for Professional SMATV

Advanced digital multi-band amplifier designed for professional SMATV installations and extensive individual installations with selective signal processing.
Enables selective processing of DVB-T/T2 signals in VHF and UHF bands with in-band channel conversion and individual level adjustment for each MUX.
Integrates DAB digital radio (174-230 MHz) and FM radio (87.5-108 MHz) signals in wideband mode without the need for channel programming.
Features AUX input (47-862 MHz) for cooperation with external modulators and headends, enabling hybrid TV distribution systems.
Equipped with advanced LTE/5G filtering with OFF / LTE 800 / LTE 700 (SAW) modes, ensuring high immunity to interference.
SMART SCAN function for automatic DVB-T/T2 signal search, facilitating installation and commissioning.
High-precision DSP platform with automatic gain control (AGC) and effective reduction of intermodulation distortion (IMD3 up to 122 dBµV).
100% compatible with collective installations, developed for optical and traditional installations.

Key Features

Digital selective DVB-T/T2 signal processing (DSP)
Channel conversion within VHF and UHF bands
Individual level adjustment for each MUX and global output adjustment (88-118 dBµV)
Wideband DAB mode (174-230 MHz) without programming
Advanced LTE 700 / LTE 800 filtering with active SAW filter
SMART SCAN function – automatic signal search
Intelligent preamplifier power control (Auto Preamp Control)
High resistance to overload and interference (IMD3 up to 122 dBµV)
Class A shielding according to EN 50083-2
Compact metal housing with IP40 protection rating
AUX channel for connection of headends and modulators
Wide output level adjustment – ideal for optical installations
Improved signal quality parameters (MER and BER)
New, greater input signal dynamics

Application Scenarios

1. Community installations in multi-family buildings	Selective processing and equalization of DVB-T/T2 levels from different directions. Channel conversion and precise adjustment ensure stable reception at all subscriber outlets.
2. Commercial facilities: hotels, guesthouses, schools	Integration of DVB-T/T2, DAB, and FM signals in a single installation. Wideband DAB mode allows digital radio distribution without channel programming.
3. Installations in challenging reception conditions	Signal parameter stabilization in locations with large level differences and LTE/5G interference thanks to LTE filters (including SAW for 700 MHz) and AGC.
4. Upgrading existing SMATV installations	SMART SCAN function enables quick search for available multiplexes. Digital processing adapts the installation to the current frequency plan without replacing antennas or cabling.
5. Integration with modulators and headends	AUX input allows working with external DVB-T/T2 modulators and small headends for hybrid TV distribution and information services in public facilities.
