  • Traffic switching in communications satellites
    Patent number: 4109202
    Abstract: A channel switching system useful in a satellite for amplifying some or all of three different RF frequency-band channel signals in two traveling wave tube amplifiers and transmitting the signals via two spot antennas to two regions on earth. Two signals are normally amplified in the two amplifiers and directed to the two regions on earth. A third frequency channel signal can be simultaneously applied through one or the other of the two paths. If an amplifier fails, the third frequency channel can be directed through the remaining operative amplifier to either one of the two regions on earth.
