Dielectric unveiled a product innovation that reimagines the RF filter topology as an analysis and troubleshooting point for TV and FM radio engineers. New for NAB Show 2023, Dielectric will introduce its new Advanced Filter Topology solution, enabling broadcasters to proof feeds within the filter as they exit the transmitter and approach the RF load or the antenna.
Designed primarily for low-power broadcasters, Dielectric’s innovation eliminates the traditional RF switch and other interconnections between the filter and transmitter. The company says the “switchless switch” approach creates a single unit that is easy to install, easy to manage, and easy on budgets.
“The LPTV repack phase gave us a new perspective on the challenges that low-power broadcasters face with the footprint, costs and maintenance of their RF systems,” said Cory Edwards, Southeast Asia Sales and OEM Manager, Dielectric. “We heard from many of our customers that a single solution to send TV and FM feeds directly into the antenna and dummy load would make their lives easier. We began developing a solution that would meet this demand.”
Edwards notes that this is not just a U.S. low-power TV and FM solution, as most broadcasters outside North America operate at lower power levels. And no matter where the station is located, the costs and complexity are substantially reduced, according to the company. In addition to eliminating the dedicated switch, Dielectric’s solution removes plumbing systems and interconnecting components that absorb space inside the facility.
Dielectric will demonstrate the technology at its NAB Show 2023 booth (W3601). Dielectric Electrical Engineer Anthony Traviglini will present a paper on the topic as part of the Broadcast Engineering and IT Conference. Traviglini’s presentation, Utilizing Advanced Filter Topology as Your New Switch, takes place Tuesday, April 18, at 10:40 a.m. in Rooms W216-218. NAB Show 2023 takes place April 16-19, at the Las Vegas Convention Center.
