ABSTRACT:
This invention reduces the number of amplifiers needed and thus reduces the weight of a multi-beam transmitting system. Each input beam is connected respectively to each switched terminal of an input switch. The fixed terminal of the input switch is connected to the input of an amplifier the output of which is connected to the fixed terminal of an output switch. Each switched terminal of the output switch is connected respectively to transmit feeds which are located off-set from the prime focus of a transmit reflector antenna. Both the input and the output switches are switched synchronously. The invention includes MMIC and high Tc superconducting transmit systems. The invention includes design to prevent single point failures and a design to transmit a large amount of RF power.
