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.
