Microstrip semiconductor mount with composite ground plane
Abstract
Abstract THE PRESENT INVENTION IS A NEW FORM OF MICROSTRIP MOUNT FOR TWO-TERMINAL SEMICONDUCTOR DEVICES. ITS ELEMENTS INCLUDE FIRST: A LARGE RADIAL CAPACITOR WHICH ACTS AS A DC CONNECTOR AND AN RF DECOUPLER BETWEEN A DC, BIAS SOURCE AND ONE SUCH DEVICE, AND ALSO ACTS AS A COMPOSITE GROUND PLANE FOR THE RF SIGNAL GENERATED IN THE DEVICE, AND SECOND, AN ADJUSTABLE CONDUCTIVE BRIDGE WHICH PROVIDES A DC PATH TO ONE OF THE DEVICE TERMINALS FROM ONE SIDE OF THE RADIAL CAPACITOR AND THROUGH THE CAPACITOR FORMS A CAVITY WHICH RESONATES AT THE DESIRED FREQUENCY WITH THE REACTANCE OF THE DEVICE. IN ONE ILLUSTRATIVE APPLICATION, THE INVENTION IS USED IN THE CONSTRUCTION OF A MICROWAVE IMPATT OSCILLATOR HAVING AN EXTREMELY LOW Q AND CONSEQUENTLY A VERY HIGH LOCKING FIGURE OF MERIT.
