Abstract: A design methodology for a DRO that facilitates the development of the DRO. The methodology involves providing an electrical length of approximately 180 degrees or a multiple thereof from a region interior to a field effect transistor to a puck-resonator line interaction region, providing an electrical length of approximately 180 degrees or a multiple thereof from a region interior to the field effect transistor to the signal end of a source feedback transmission line, and providing an electrical length of approximately 90 degrees or an odd multiple thereof from a varactor diode signal ground to a puck-tuning line interaction region. Other aspects relate to a DRO resonator transmission line and a DRO tuning transmission line having a portion formed on a higher dielectric substrate to concentrate the electromagnetic field, and a portion on a lower dielectric substrate to expand the electromagnetic field near the dielectric resonator puck.

Abstract: A frequency-adjustable direct current biasing circuit is disclosed for providing a DC bias voltage or a DC connection to ground for an RF or microwave circuit without substantially affecting the RF or microwave signal of the circuit. The biasing circuit includes a transmission line having a first portion for connection to the RF circuit and a second portion connected to a low-impedance-to-ground structure, such as a bypass capacitor or a DC path to ground. The electrical length between the first and second portions is about 90 degrees. The biasing circuit further includes an open ended tuning stub coupled to the transmission line that has a length that is adjustable. By adjusting the length of the tuning stub, the biasing or grounding circuit can provide better isolation for RF energies at different selected frequencies. Also disclosed herein is a dielectric resonator oscillator (DRO) that uses the frequency-adjustable biasing circuit. Further disclosed is a DRO that includes a FET gate return having an RF-shunted, relatively high resistance coupled to the gate of a field effect transistor by way of a quarterwave transmission line. This improved FET gate return provides for reduced phase noise of the DRO.

Abstract: The microwave oscillation circuit provides a transistor having the collector electrode grounded, the base electrode connected to a resonator circuit determining the oscillation frequency, and the emitter electrode connected to an output open stub. An output transmission line is placed parallel to the output open stub for the output power supplied from the output open stub to be output via an end of the output transmission line to a buffer amplifier. A resistor having an impedance equal to a characteristic impedance of the output transmission line connects a stub circuit to an open end of the output transmission line. The stub circuit exhibits an infinite impedance at the oscillation frequency. At the oscillation frequency, the resistor floats due to the infinite impedance of the stub circuit so that all the oscillation power supplied from the output open stub is output to the buffer amplifier, without being consumed by the resistor. At frequencies other than the oscillation frequency, where the buffer amplifier is likely to be unstable, the output impedance of the output transmission line is damped enough to prevent the buffer amplifier from its unstable condition, because the resistor is grounded by a relatively low impedance of the stub circuit.

Abstract: An electronically tuned dielectric resonator stabilized oscillator has a dielectric resonator that is fine tuned by an electronic method of tuning which includes a varactor coupled to a microstrip. This varactor microstrip transmission line is positioned below the dielectric resonator but above the plane in which a transmission line for the carrier frequency resides. By not placing the fine tuning microstrip line on the same plane as the main oscillator line, spurious oscillation between the fine tuning transmission line and the primary carrier wave resonator frequency line are minimized. Additionally, the fine tuning microstrip line is positioned orthogonal to the pathways along which the main signal transmission lines are coupled.
