ABSTRACT:
A transistor device for a microwave oscillating element having an FET transistor chip and a package encapsulating the chip therein. In order to avoid any affection of the external circuit to the input impedance of the transistor device and to make the phase rotation low at a frequency band higher than the X band, a conductor element is provided within the package to connect the drain electrode of the chip and a corresponding terminal of the package. The conductor element has an inductance to provide a sufficient high impedance at the intended frequency band. The conductor element is supported on an insulator plate fixedly mounted within the package.
