Electronics Research, Inc. (ERI) will introduce a revolutionary high level diplexer to combine analog and digital (HD Radio) with greater efficiency and better performance than other techniques currently in use. The All Pass Diplexer system does not have the high insertion loss of 10 dB hybrid injectors, which waste significant amounts of analog and digital transmitter power.The All Pass analog insertion loss is -0.35 dB or less and the digital loss is -1.4 dB or less. In addition, the group delay performance is superior to alternative high level combining methods and is readily correctable by currently available FM transmitters. Group delay of the analog signal is less than 350 nanoseconds and the digital delay is less than 600 nanoseconds. The Model 788 All Pass Analog/IBOC Diplexer is rated for up to 30 kW analog and up to 5 kW digital input power.
The All Pass Diplexer gives FM radio stations that are currently operating a -20 dBc IBOC power level with a 10 dB hybrid injector the opportunity to increase digital power without having to invest in a new transmitter.
A paper that includes the application and performance capabilities of the All Pass Diplexer will be presented by ERI’s President and CEO Thomas B. Silliman and ERI RF Engineer Nicholas Paulin as a part of the NAB 2012 Broadcast Engineering Conference. The paper will be presented on Sunday April 15 at 2:00 pm in Room S228 of the Las Vegas Convention Center. ERI will also have information available at its NAB Exhibit Booth C2222.
