Patent ID: 6911938

Claim:
A transmit-receive telecommunication system comprising of: a multibeam transmit system comprising: a plurality of input beams, 1 to n, forming a first set; a second set of unput beams, 1 to n, is connected in parallel to said first set respectively; two input switches; each switch has 1 to n switched terminals; each switch switches a set of said input beams respectively; two input redundant switches; each input redundant switch has a fixed terminal; said first input redundant switch switches between said input switches; said fixed terminals of said input redundant switches are connected together; two amplifiers each having an unput and an output; said second input redundant switch switches between the inputs of said amplifiers; two output redundant switches; each said output redundant switch has a fixed terminal; said first output redundant switch switches between the outputs of said amplifiers; said fixed terminals of said output redundant switches are connected together; two output switches each having switched terminals 1 to n; said second redundant switch switches between said output switches; a plurality of transmit feeds, 1 to n, forming a first set; a second set of transmit feeds 1 to n, connected in parallel with said first set of transmit feeds respectively; each said output switch switches a set of transmit feeds respectively; said transmit feeds are located offset from the prime focus of a transmit reflector antenna thus forming output beams 1 to n; said input and said output switches are switched synchronously at a constant rate; input beams 1 to n produce output beams 1 to n respectively; only two amplifiers amplify signals from n input beams reducing the weight of said transmitting system; only two amplifiers amplify signals from n input beams reducing the power requirements of said transmitting system; only two amplifiers amplify signals from n input beams reducing the cost of said transmitting system; a plurality of receiving areas 1 to n; output beams 1 to n form receiving areas 1 to n respectively; a receiving area containing: a plurality of receiving systems 1 to k; a receiving system comprising a receive feed located at the prime focus of a receive reflector antenna; and a receive feed is connected to a receiver.
