Description
Our Av-Comm C Bandpass Filtered LNB PLL 3.9-4.2GHz 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 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 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.
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.
