AVQ1010 - ActiveCore® Transmitter Efficiency Enhancing Platform



Targeted to the digital audio and TV broadcasting industry, Avateq's ActiveCore® Platform presents an innovative approach to enhancing broadcasting transmitter efficiency and functionality. Being integrated in to a transmitting system, ActiveCore® Platform serves as a central device to control and monitor the system performance. The Platform combines the most innovative and leading-edge functionalities: adaptive DPD with a high performance signal PAR reduction core, echo and feedback interference canceller, broadcasting signal monitoring receiver and signal envelope tracking.

ActiveCore® Platform is available as a stand-alone unit or an OEM module and can be easily integrated into a broadcasting system or power amplifier thanks to its intelligent "RF in - RF out" design. A broadcasting equipment and transmitter manufacturer can now take full control over the system efficiency and performance for virtually any standard found in the broadcasting industry without relying on the modulator used in the system.

The platform eliminates the necessity to adjust or tune a digital broadcasting transmitter or the transmitter's operational parameters in order to account for the modulator design and/or broadcasting standard specifics. This allows designing and manufacturing virtually standard independent digital broadcasting transmitters or power amplifiers that provide significant flexibility in terms of selecting a modulator for a particular application.

By integrating the ActiveCore® Platform into a digital transmitter system, a broadcasting equipment manufacturer adds enhanced functionality to the whole system and, therefore, increases practical value for its product.

The platform can be used as a broadcast monitoring system (an integrated monitoring receiver) in remote applications for digital repeaters in broadcasting networks.

A stand-alone unit allows for easy in-field upgrade of existing digital broadcasting systems.
