Abstract:
A multiport semiconductor alternating current (AC) switching apparatus comprising:a first semiconductor switching leg coupled between a first port and a second port, said first semiconductor switching leg operable for bi-directional AC signal transport thereover in response to the application of a first DC biasing signal to said first semiconductor switching leg;a second semiconductor switching leg coupled between a third port and a fourth port, said second semiconductor switching leg operable for bi-directional AC signal transport thereover in response to the application of a second DC biasing signal to said second semiconductor switching leg;a third semiconductor switching leg coupled between said third port and said second port, said third semiconductor switching leg operable for bi-directional AC signal transport thereover in response to the application of a third DC biasing signal to said third semiconductor switching leg; anda fourth semiconductor switching leg coupled between said fourth port and said first port, said fourth semiconductor switching leg operable for bi-directional AC signal transport thereover in response to the application of a fourth DC biasing signal to said fourth semiconductor switching leg;wherein said second port and said fourth port are not coupled to a reference potential; andwhereby either of said first port or said third port may be selectively coupled to either of said second port or said fourth port upon application of respective DC biasing signals.
