Abstract:
1. A six-port circuit with first (V in1 ) and second (V in2 ) input ports and four output ports (V out1 , V out2 , V out3 , V out4 ), the six-port circuit comprising a balun including an unbalanced end connected to the first input port (V in1 ) for converting a first input signal at the first input port into first and second balanced input signals; a filter including first (V′ in1 ) and second (V′ in2 ) input ports (V′ in1 , V′ in2 ) and four output ports which constitute the four output ports (V out1 , V out2 , V out3 , V out4 ) of the six-port circuit; and a power splitter connected to the second input port (V in2 ) for splitting a second input signal at the second input port into a first and a second part of the second input signals, wherein the two input ports (V′ in1 , V′ in2 ) of the filter are connected so that one of the balanced input signals and one of the parts of the second input signals are connected to one of the filter's input ports (V′ in1 ), and the other of the balanced input signals and the other of the parts of the second input signals are connected to the other of the filter's input ports (V′ in2 ).
