The Av-Comm L1521 C Band 5G Filtered PLL LNB 3.9-4.2GHz provides a single polarity C Band 5G filtered LNB solution with an input range of 3.9–4.2GHz The Av-Comm C Band 5G Filtered PLL LNB 3.9-4.2GH model LNB provides +/-300kHz Phase Lock Looped (PLL) stability, ideal for use SCPC, MCPC and higher rate signals.
The Av-Comm C Band 5G Filtered PLL LNB 3.9-4.2GHz +/-300kHz LNB is designed to be used on commercial C Band systems severely impacted by terrestrial 5G interference. The restricted input frequency of the Av-Comm C Bandpass Filtered LNB combined with the addition of a bandpass filter ensures that any terrestrial 5G interference originating within extended C Band (3.4-3.7GHz) or standard C Band (3.7-3.9GHz) is rejected from the input before conversion and processing, ensuring nominal C Band downlink performance. One of the key benefits of using an Av-Comm C Band 5G Filtered LNB when compared to using a standalone waveguide filter is that Av-Comm’s LNB solution does not suffer from insertion loss unlike standalone waveguide filters. This ensures there is no degradation of the carrier to noise ratio (C/N) of the received signal when using an Av-Comm C Band 5G Filtered LNB.
Av-Comm has written a C Band 5G Interference White Paper that provides insight into why 5G interference is impacting C Band reception in Australia and the industry best practise method to resolve C Band interference issue for location and license area throughout Australia.
