Abstract

PURPOSE:To enable the selection of the output frequency freely with less loss, by combining the periodic type branching unit having two paris of the input and output terminals and the switch having three input and output terminals. CONSTITUTION:Taking the transmission frequency of the transmitter TX1 as F1 and that of the transmitter TX2 as F2. F1 and F2 are synthesized at the input and output terminal 29 of the periodic type branch unit PF19 and picked up. When the waves of F1...Fn are input to a pair of inputs of the periodic type branch unit, the outputs of F1, F3...are picked from one output and these of F2, F4... from another output with the operation of the directional coupler and the phase shifter in the unit. That is, if the transmission is made with F2 for TX1 and F1 for TX2, the synthesized wave is appeared at the output terminal 30. The transmission can be made with almost no loss even if the transmission frequencies of TX1 and TX2 are selected so that an odd or even number is not given.
