RFS showcases new filters, combiners

Radio Frequency Systems (RFS) featured its new Peak Power+ line of filters and combiners last month at IBC2009 in Amsterdam.

The new filters have been conceived for the high peak-to-average power ratio nature of digital television (DTV) and represent a breakthrough in coaxial filter technology.

While the average RF power level of DTV is similar to that of traditional analog television transmitters, its peak power is considerably higher. That can translate into problems for transmitting equipment.

RFS' new filters offer a way to bring an end to the peak power "wildfire" that sprawling DTV services are feared to spark. The filter allows DTV to be transmitted at higher power levels, taking up less space than previous solutions, and thus permitting the addition of channels and services in the same site.
