A high isolation electronic multiple pole multiple throw (MPNT) switching device is formed as a ring circuit that includes plural poles, plural throws, plural series switches and plural means for shunting. Each series switch receives a control signal, and each means for shunting receives shunt control signals. In one aspect, the shunt control signals include control signals received by distant series switches. In another aspect, the shunt control signals include control signals received by adjacent series switches. In another aspect, the shunt control signals include signals complementary to signals received by adjacent series switches. In another aspect, the shunt control signals include pole DC potentials or throw DC potentials. In another aspect, a switching device may operate in multiple transmission mode or multiple input multiple output (MIMO) mode. The MPNT switching device provides low insertion loss and high isolation at a wide range of frequencies.
