Microwave semiconductor device comprising stabilizing means |
摘要 |
A semiconductor device microwave integrated circuit includes at least a transistor stage which stage includes a microwave matching circuit and a d.c. bias circuit interconnected at a link node (A). The transistor stage further includes a stabilizing circuit which includes an open stub line connected to the link node. The open stub line connected to the link node is a lambda /4 line which at the operating frequency imposes a short circuit on the link node. A matching circuit made up of a low-value resistor connected to ground in the microwave mode through a d.c. isolating capacitor is connected to the link node. A lambda /4 line of the radial type ( lambda /4 radial stub) provides broadband operation.
