Details
The WWK ALPHA 2 is an advanced digital multi-band amplifier designed for professional SMATV antenna installations and extensive individual installations. The device enables selective processing of DVB-T/T2 signals in the VHF and UHF bands, integration of DAB and FM signals, as well as cooperation with external modulators and headend stations via the AUX input.
The DSP platform allows precise level regulation of each multiplex, channel conversion within the band, automatic adjustment of the
amplification (AGC) and effective reduction of intermodulation distortion. The amplifier features advanced LTE/5G filtering (including SAW filter for the 5G 700 band), intelligent power control of antenna preamplifiers and automatic signal search (SMART SCAN).
amplification (AGC) and effective reduction of intermodulation distortion. The amplifier features advanced LTE/5G filtering (including SAW filter for the 5G 700 band), intelligent power control of antenna preamplifiers and automatic signal search (SMART SCAN).
The WWK ALPHA 2 provides stable operation even in difficult reception conditions, with large signal level differences and high LTE and 5G emission densities, meeting the requirements of modern collective and site installations.
Key features:
- digital selective processing of DVB-T2 signals (DSP)
- channel conversion within the VHF and UHF bands
- individual level control of each MUX and global output control
- wide band DAB mode (174-230 MHz) without channel programming
- advanced LTE 700/LTE 800 filtering, SAW filter active in LTE 700 mode
- SMART SCAN function - automatic search for DVB-T2 signals
- intelligent power control of preamplifiers (Auto Preamp Control)
- high immunity to overdrive and interference (IMD3 to 122 dBµV)
- shielding Class A to EN 50083-2
- compact metal housing
- AUX track for easy connection of headends and modulators
- extensive output level control - ideal for optical installations
- even better signal quality parameters - MER and BER
- new, higher dynamics of input signals
The WWK ALPHA 2 enables selective processing and level adjustment of DVB-T2 signals received from different directions. Thanks to channel conversion and precise level adjustment, each multiplex can be adjusted to the requirements of the installation, ensuring stable reception in all subscriber outlets. The device allows DVB-T2, DAB and FM signals to be integrated into a single installation. The wideband DAB mode enables digital radio distribution without channel programming, and the high resistance to overdriving guarantees reliable operation in extensive networks. In locations with large differences in signal levels and the presence of LTE/5G interference, the WWK ALPHA 2 stabilises signal parameters with LTE filters (including SAW for the 700 MHz band), automatic gain control and high intermodulation resistance.
