In this article the parametrically coupling of oscillations in a small ellipsoid of ferrite under the excitation of an uhf pumping of any spatial distribution is discussed. It is pointed out that the coupled oscillations may be induced through the two types of driving, field driving and magnetization driving. A special case of the former was recently discovered by Denton, who used a longitudinal pumping field uniform in space. A special example of the latter is found in Suhl's theoretical analysis and a number...

In this article the parametrically coupling of oscillations in a small ellipsoid of ferrite under the excitation of an uhf pumping of any spatial distribution is discussed. It is pointed out that the coupled oscillations may be induced through the two types of driving, field driving and magnetization driving. A special case of the former was recently discovered by Denton, who used a longitudinal pumping field uniform in space. A special example of the latter is found in Suhl's theoretical analysis and a number of experimental works after him. The pumping field transverse in direction and spatially uniform does not induce the coupled oscillations directly, but the rf magnetization of the Kittel precession excited by the pumping becomes the driving force of the oscillations. For each type of a uniform pumping we obtain from a set of differential equations the magnetostatic potential functions (the first order approximation) as linear combinations of Walker's functions. These solutions are different from those given by MOHOCOB. Making. use of the boundary conditions at the ferrire surface we find that for the Walker modes involved in the oscillations to be coupled, thtir indices must satisfy certain condi'ions. For the case of magnetostatic operations the dc magnetic field is tuned to a pair of the Walker modes, the potential functions may be reduced greatly. By studying the power drawn by the coupled oscillations from the pumping, we obtain the selection rules of a pair of magnetostatic modes excited by a pumping field of any given spatial distribution. We point out that for the determination of the amplitudes of the oscillations the equations derived from the conservation of energy and from the equality of the number of quanta emitted must be used. Finally, the threshold intensity of Denton's pumping field is derived using Suhl's method. We indicate that this method is based on a perturbation calculation.

在本文中我们系统地讨论了铁氧体小样品在超高频电源的激发下产生参量振璗的耦合关系,指出激发机构应分为磁场驱动和磁化驱动二类。前者的特例为Denton新近发现的,使用空间均匀的纵向注入场;后者的特例为Suhl最早所研究的,使用空间均匀的横向注入场所激发的一致进动的磁化向量为驱动力。从静磁势函数的耦合微分方程我们得到这二种特殊注入方式激发的静磁势函数的完全解(一次近似),表达为Walker函数的线性组合,在边界连续的要求下,这些势函数中的Walker模只在它们的指标之间适合一定的条件时才相互关联。当直流磁场调谐于一对Walker模时,耦合的静磁势简化为静磁操作的势函数。我们具体分析了静磁操作参量振璗从注入场吸取的功率,根据后者必须不为零才可能产生参量振璗,我们推导出空间均匀场激发一对静磁模的选择定则,恰与从边界连续推出的关联条件完全相同,并且进一步得到空间不均匀场激发一对静磁模的选择定则。我们指出,参量振璗的振幅的决定必须引用能量守恒和量子数相等的方程。最后我们采用Suhl的方法推算出空间均匀的纵向注入场的激发临阈强度,并且讨论了这一方法的近似性质。

Some supplementations, unifications, and simplifications of the problem of optimum band-width of a filter approximately matched to high-frequency pulsed signal were made in this paper.For a filter approximately matched to a single rectangular high-frequency pulse, the case for a linear system with rectangular freguency characteristic detuned with respect to the rectangular high-frequency signal was discussed and the formula for calculating the optimum band-width of the system was obtained.For the case of pulse trains with uniform amplitudes, simplification and unification of some results of the other authors were made, it was pointed out that there exists a simple relation between the optimum value of attenuation of the delayed feedback system with unlimited band-width and the optimum teeth-width of a comb filter with single-tuned characteristic of the teeth. The comparison between these two systems was made by the use of the data of the other authors.For the case of rectangular pulse trains with non-uniform amplitudes, the accumulation of the rectangular pulse trains with trapezoidal envelope by the delayed feedback system with finite bandwidth was discussed, and formula of the signal to noise ratio at the output terminals was obtained. For finding the optimum bandwidth of the delayed feedback system, some numerical calculations were made, and curves of the signal to noise ratio with respect to the band-width were plotted. From these curves we found that in this case there exists an optimum band-width of the system, the value of which is wider then the optimum band-width of the system in the case of accumulation of rectangular pulse trains with uniform amplitudes.

This paper describes a design method of multi-stage transistor intermediate frequency wide band amplifier. The feature of design is the use of network synthesis technique for realizing the amplifier with Tschebyscheff or maximal flatness frequency characteristics. The amplifier itself consists of a cascade of RC neutralized common-emitter stages each with primary tuned interstage transformer. The discussion is divided into three parts. First, the neutralized common-emitter stage is represented by approximate unilateral equivalent circuit. Second, the interstage network is analyzed. Expressed the transistor amplifier power gain as a prescribed frequency function, it is possible to derive the limiting constraints for resonant frequencies and Q values of interstage networks, and subsequently to obtain values of circuit elements. These resonant frequencies of interstage networks are not tuned to the center frequency, but distributed at certain frequencies of the transmission band. Finally one design example is presented.
