ABSTRACT:
A transmission system for use in a communications satellite is disclosed which utilizes a power divider providing equal power output from N output ports having a uniform phase progression from port to port, the sense of which depends upon which of two input ports is excited. In an illustrated embodiment, one input port generates a first sense of circular polarization and the other generates the opposite sense. The two oppositely polarized circular waves are applied to the multiphase power divider. The cylindrical-bodied power divider has N output ports, where N is an odd integer, arranged at 360.degree./N about the cylindrical surface. Disposed within the power divider is an N-bladed septa for providing power division and isolation. A 180.degree. phase inverter is connected to (N-1)/2 output ports for providing a wave having a phase progression of 180.degree./N from the power divider.
