Abstract:
Miniature narrow band filters with high performance can be formed by means of high Q and low temperature coefficient dielectric resonators, such as barium titanate, which are reasonably placed in a cut-off waveguide and properly excited. This paper d...

Abstract:
In this paper, making use of the rotatory transform, the negative resistance condi-tions of five typical amplifiers are determined. Using the phenomena of combination oscillation existing only in the negative resistance effect, we obtained the result...

Abstract:
Based on actual M-sequence autocorrelation function, this paper has formulated the system impulse response function with the method of correlation, given a discussion for the measurement of impulse response function of phase locked loop, derived the ...

Abstract:
In the kinetics of electron cyclotron masers, the method based on the local field expansion in the guiding center frame has many advantages. In this paper, an equil-librium function of electrons applicable to this method is given. The function specif...

Abstract:
In this paper, the influences of phase difference between two single tubes of dual-TR tube on receiving lose and receiving VSWR in balaneed duplexer are investigated exper-imentally. The experimental results show, if the phase differenee is greater t...

Abstract:
The eonversion coefficient of a TWT can be reduced, when it works at under-voltage condition. Therefore if a section of helix which works at under-voltage condition is added to a TWT, the improvement of AM-PM eonversion coefficient can be expected,th...

Abstract:
This paper suggests a new a scheme for a laser aecelerator according to the principle of geometrie opties. A lens with special non-spherical surface is used to focus the laser rays onto the axis. The phase of these rays can be continuously adjusted a...

Abstract:
Using DC and pulse retarding field methods, we have measured the effect of in-creasing primary electron energy on the secondary emission coefficient of W-Y2O3 cermet cathode at room-temperature, and the variation of the first crossover and the maximu...
