Technological Solution for Enabling 5G NR and TVRO Peaceful Coexistence in C-band

This work proposes a technological solution for allowing a peaceful coexistence between 5G New Radio (5G NR) and satellite Television Receive Only (TVRO) services in C-band. A detailed analysis and an efficient redesign of a typical low-noise block converter feeder (LNBF), used by TVRO home users, is conducted aiming to reduce the 5G NR interference, which is going to operate at TVRO adjacent channels in some countries. Basically, we exploit two enhancements on the LNBF topology, namely: increasing the 1 dB compress point (P1dB) (input) level of its low noise amplifiers (LNAs), in both first and second stages; incorporating a low-cost and high-performance passband RF filter. As the main contribution, it is demonstrated the protection distance - calculated in accordance to the International Telecommunication Union (ITU) recommendations- might be significantly reduced from 20.85 km to only 22 m, by using the proposed high-performance LNBF.
