Abstract:
Reference [1] concluded that for the phase-locking of Gunn Oscillator, timing by varying the bias voltage on the diode is not a practical method. However the author of this paper successfully realized the 8mm (35 GHz) phase-locking standard fre-quenc...

Abstract:
In this paper, a method of analysing the short backfire antenna is proposed. Using this method, a new type backfire antenna is developed. Its gain is about 2.5 dB higher than that of a normal short backfire antenna.

Abstract:
VVMOS transistor is a new type of high frequency power MOS transistor with vertical channels at the surface of the V-groove. Like other MOSFET s, one of the important features is no secondary breakdown, However, these is negative resistance breakdown...

Abstract:
In this paper, we propose a new eriterion and a method for designing filter type output circuit of broadband klystrons. From this, we ean obtain an output section which satisfies the requirement of klystron designs, and have good impedance-band-width...

Abstract:
Pulse emission current at the inflection point on I-U curve of a thermionie eathode can be measured rapidly by means of a circuital technique. This method can prevent the eathode from suffering injury during the measurement. So that it can be used to...

Abstract:
A new empirical formula for calculating the Tc, of A-15 supereonductors is presented and it reads: Tc=N TA/M1/2(rA/rB) (e/a), where Nnumber of atoms,N = 4 for A3B compounds; TA the superconductive transition temperature of the A element; Mthe. averag...
