www.DataSheet4U.com TA0321 TECHNICAL ARTICLE Lightning protection for LNB supply and control voltage regulator Introduction Communication satellites operate within two frequency bands for TV/Broadband service broadcast signals, C Band and Ku Band. The C Band overall frequency spectrum is 4.0 GHz - 8.0 GHz, while the Ku Band overall frequency spectrum is 10.7 GHz - 18.4 GHz. Within these bands each satellite has a specific uplink and downlink frequency allocation. For example: ■ ■ Ku Band downlink frequency is 10.7 GHz-12.75 GHz and uplink frequency is 17.3 GHz-17.8 GHz. C Band downlink frequency is 3.7 GHz-4.2 GHz and uplink frequency is 5.925 GHz-6.
