|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...
|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....
