The 5G signal frequency occupies part of the C-band frequency range. For a tuner, the C wave band comprises an extended C wave band and a standard C wave band, the downlink frequencies are 3 400MHz-3 700MHz and 3 700MHz-4 200MHz respectively, and signals of the wave bands are easily interfered by common-frequency signals.
In the process of checking the problem that 5G signals interfere C-band satellite signals, a narrow-band tuner is found to be capable of solving the 5G interference, but the precondition is that the 5G signal strength near the antenna is weak, or the C-band antenna is located in a wide suburb area and no complex electromagnetic environment exists around the antenna. However, the sites of the 5G base stations in the main urban area are dense, the antenna orientation may be right opposite to the base station or the central urban area in which the electromagnetic environment is extremely complex, and the signal intensity transmitted by the 5G base station is much greater than the satellite signal intensity of the C-band, so that the anti-interference requirement cannot be met even with a narrow-band tuner, the 5G signal can still saturate the tuner performance, thereby affecting signal reception, and the decoding picture shows a checkered screen or mosaic, and the numerical value shows that the error rate of the receiver is increased, so that a new filtering anti-saturation measure must be taken.
