Abstract: A sweep signal generation system for producing an output sweep signal of very high frequency includes a circuit for generating an input sweep signal, and a phase locked loop which includes a phase detector, a voltage controlled oscillator and a harmonic frequency mixer. The output sweep signal is applied to the harmonic mixer together with a local oscillator signal of fixed frequency, the output from the harmonic frequency mixer being applied to the phase detector together with the input sweep signal. The output from the phase detector is applied to the voltage controlled oscillator to cause the frequency of the output thereof to be swept in accordance with variation of the input sweep signal.

Abstract: A device for generating a signal varying in frequency from 1 to 18 GHz at aonstant output power. The device utilizes a tracking automatic level loop and reacquire loop which provide automatic alignment of a YIG multiplier filter with a YIG voltage-controlled oscillator (VCO). Adjustability of output power level control is provided in the tracking automatic level loop with a provision for LED display when the device loses lock.

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.
