TA0321, TECHNICAL ARTICLE

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 Ba
