Embodiment Construction

[0018] The present invention will now be described in detail with reference to the accompanying drawings. figure 2 is a perspective view showing a multiplying device used in the frequency multiplying method of the present invention. exist figure 1 The frequency doubling device 10 shown in includes a cavity resonator 1 and a ferromagnetic thin film 2 having a resonant frequency f on the inner bottom wall surface 1B of the cavity resonator 1 . Aperture 3 is formed at wall surface 1A of cavity resonator 1 opposite to ferromagnetic thin film 2 , and slit 4 is formed at side wall surface 1C of cavity resonator 1 .

[0019] An electromagnetic wave E having a given input frequency to be multiplied is introduced from the aperture 3 into the cavity resonator 1 . In this case, the input frequency of the electromagnetic wave needs to be equal to the resonance frequency of the ferromagnetic thin film 2 . As described above, since the resonance frequency f can be varied in a wide range...

Abstract

The invention relates to a method and device for doubling frequency, a ferromagnetic thin film with its natural resonant frequency is located in a cavity resonator. Then, the electromagnetic wave whose input frequency is equal to the resonant frequency of the ferromagnetic thin film is introduced into the ferromagnetic thin film from the aperture of the cavity resonator, and ferromagnetic resonance is generated in the ferromagnetic thin film, thereby multiplying the input frequency of the electromagnetic wave.

Description

technical field [0001] The present invention relates to a method and equipment for multiplying frequency, especially suitable for microwave technical field and high frequency technical field which need to effectively multiply frequency from mobile communication equipment or cellular information equipment. Background technique [0002] The frequency generated and transmitted by the mobile communication device or the cellular information device is multiplied by the non-linear resistance property of the crystal detector. However, in this case, operation becomes complicated because many elements must be controlled and matched. [0003] Instead, monolithic microwave integrated circuits are used, in which specific microwave circuits used as high-speed, high-frequency circuits are fabricated on one substrate. Since mass production of monolithic microwave integrated circuits is well scaled, it is suitable for commercial applications. However, such monolithic integrated circuits ar...
