  • Microwave voltage controlled oscillator formed and located on a high dielectric loss substrate with a controlled circuit
    Patent number: 6326857
    Abstract: A voltage controlled oscillator formed as a first layout with metallized areas by a planar technique is located on a high dielectric loss substrate. A second layout formed of metallized area for control circuits of the voltage controlled oscillator is formed on a high loss dielectric substrate is also formed by the same technique as the first layout. A ground plane for the controlling oscillator is formed on an opposite side of the dielectric substrate on which the voltage controlled oscillator is formed.

  • Microwave oscillator with improved phase noise characteristic
    Patent number: 5463360
    Abstract: A microwave oscillator has a cavity which is excited with an active element. The phase noise characteristic of the oscillator is improved in that a frequency discriminator utilizes the same oscillator cavity. The waves transmitted and reflected by the cavity are measured, combined and detected by a pair of low noise diodes. The signals obtained are compared to produce a control signal for a phase shifter which is connected between the active element and the cavity. The cavity is preferably a dielectric resonator.
