Abstract: An electronically tunable solid-state microwave frequency source comprises a transmission-absorption filter incorporated within a magnetic structure. The transmission-absorption filter is employed with a tunable solid-state oscillator and tunable solid-state multiplier to provide a continuously tunable microwave signal source with enhanced spurious signal attenuation over a multiple-octave tuning range. The filter structure comprises a sphere of monocrystalline garnet such as yttrium iron garnet (YIG) and two coupling loops disposed in the field region of an adjustable field DC magnet. The coupling loops are disposed orthogonal to the magnetic field and to each other. In a specific embodiment the first coupling loop is operative to receive at its input the fundamental frequency signal and at its output is grounded, and the second coupling loop is operative to receive a harmonic input signal at its input and to convey a desired output signal at its output. The magnetic sphere of the transmission-absorption filter typically shares the magnetic field of the YIG sphere used to produce the output of the tuned oscillator. The transmission-absorption filter is incorporated into a source including a switch, a fundamental frequency amplifier and a harmonic frequency amplifier.

Abstract: First and second ferrimagnetic resonator tuned circuits, such as a input filter circuit and local oscillator circuit, have their respective ferrimagnetic resonator bodies disposed in the gap of an common magnet. An auxiliary magnet is provided for producing an offset in the magnetic field intensity within one of the ferrimagnetic resonator bodies relative to the other to produce a difference in the resonant frequencies of the two ferrimagnetic resonator tuned circuits. The magnetic field of the main magnet and, in some cases, the field of the auxiliary magnet as well, are swept in intensity to produce a corresponding sweep in the resonant frequencies of the two ferrimagnetic resonator tuned circuits while maintaining a controlled frequency difference therebetween.

Abstract: A swept synthesizer signal source provides a digital synchronization signal for accurate internal synchronization of events and for external synchronization of data taking and other operations to predetermined frequencies generated by an oscillator during a sweep. The digital synchronization signal includes a predetermined number of digital pulses, regardless of the sweep time. A ramp voltage which controls the oscillator is corrected during a calibration period to sweep between predetermined limits, thereby insuring that the ramp voltage is synchronized to the digital synchronization signal. The slope of the frequency versus time sweep is also corrected to further improve accuracy. A power level correction technique insures precision power leveling regardless of the sweep range. A table of correction/frequency pairs is entered into the instrument, and an interpolation algorithm is employed to determine corrections at frequencies corresponding to each synchronization pulse. The source can be used in a network analyzer system wherein the synchronization pulses are provided to a receiver to trigger data taking. Two or more sources can be interconnected to provide synchronized sweeps.

Abstract: A tuned oscillator is disclosed which consists of an active element (1) for oscillation, a ferrimagnetic resonant element (2) connected to part of feedback of the active element (1), and a matching circuit (3) connected to the active element (1). The matching circuit (3) is designed to reflect the fundamental wave produced by the ferrimagne­tic resonant element (2) and active element (1) and pass the second harmonic wave. Consequently, the magnetic circuit has its load redu­ced in applying a D.C. magnetic field necessary for frequency tuning to the ferrimagnetic resonance element (2).
