Description
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.

- IEC61000-4-5 R = 12 Ω Note: In some tests, some customers apply an external power supply voltage in the range of +28 V DC to the coaxial cable. In this case, it is recommended to used a TVS with VRM > 28 V (SM15T33A or SM15T36A).
