Our Av-Comm C Bandpass Filtered LNB PLL 3.9-4.2GHz +/-300kHz provides a single polarity solution with C Band input range of 3.9–4.2GHz with 300kHz Phase Lock Looped (PLL) stability. This LNB is designed to be used on commercial C Band systems severely impacted by terrestrial 5G interference. The restricted input frequency of our 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.
Further, the additional frequency separation from the terrestrial 5G interfering carriers provides additional protection. This LNB is design for reception of signals in the 3.9-4.2GHz range whilst providing reception from severe terrestrial 5G interference .
The addition of the bandpass filter within the C Band LNB itself eliminates the insertion loss typically associated with standalone waveguide filters providing superior performance.
