Number	Title	Issue Date
7002434	Lumped-element transmission line in multi-layered substrate A lumped-element transmission line is formed in a multi-layered substrate. A mutual inductance between first and second inductors in a T-equivalent circuit model is enlarged to a designed positive value to widen the application frequency bandwidth of the transmissio...	02/21/2006
4891536	Solid state switch An electronic switching arrangement is shown to consist of an effective balanced pi configuration using series and shunt FETs and transformer coupling so that the impedances seen by such FETs are optimized....	01/02/1990
4199730	Double peaked amplifier 1. An audio frequency amplifier selectively responsive to a band of Doppler requencies comprising an electron tube having at least grid, anode and cathode elements, a three pi network connecting said electron tube anode and grid elements, said network prov...	04/22/1980
