ABSTRACT:
A non-reflective ring topology MPNT switching device comprises at least two poles, at least four throws, plural main switches, and plural bridge switches. The bridge switches enable all throws to be non-reflective throughout a wide frequency range. Each main switch is connected between one of the poles and one of the throws. Each bridge switch is connected between two of the throws, and each throw is connected to at least M+1 of the bridge switches, M being the pole count. In operation, each of M of the main switches has a first (ON) state and is connected to one of M active throws. For each active throw, each bridge switch connected to the active throw has a second (OFF) state. For each non-active throw, one bridge switch connected to the non-active throw has the first (ON) state and each other connected bridge switch has the second (OFF) state.
