MICROWAVE POWER UP-CONVERTERS FOR ANGLE MODULATED USING PHASE-LOCKED MICROWAVE OSCILLATORS K.-E. Schertler SIGNAL3 ABSTRACT A new technique of microwave power generation using the phase-locked loop principle is described. It combines the functions of a microwave up-converter and a microwave power amplifier and is therefore particularly attractive for heterodyne-type radio relay transmitters. Pow

TEMPERATURE STABLE DIELECTRIC MICROWAVE RESONATORS FOR HIGH POWER APPLI- CATIONS 1) 1) , H. Steyskal Sr. , L.D. Wernlund Ph. Charas 2) ABSTRACT Temperature stabilisation was obtained by combining two dielectrics with opposite temperature coefficients of dielectric permittivity to a composite resonator. Single crystals of LiNb03 were used as the part with positive coefficient, while the ot

HIGH-PERFORMANCE, GLASS STABILIZED, MICROWAVE FREQUENCY SOURCES Jing-Jong Pan and Paul Sierak ABSTRACT An ultrastable, low-noise, low-cost, fixed-frequency, S-band transistor frequency source controlled by a metallized glass cavity has been computer optimized. Frequency and temperature stabilities of 0.9 x 10-9 parts/hour and 1.8 x 10-7 parts/ºC, respectively, have been achieved. A C-band, tu

SYNCHRONIZATION AND NOISE PERFORMANCE OF TWO-FREQUENCY OSCILLATORS K. Schtinemann X and P. Plumeyer xx ABSTRACT: A nonlinear theory of multiple-frequency oscillators of the negative resistance type is developed and applied to two-frequency Gunn- and Impattdiode oscillators. The following results which were confirmed by measurements are obtained: By a high-Q loading of the second circuit a c

DESIGN IMPATT AND CONSTRUCTION OF AN INEXPENSIVE TECHNIQUE. Iperen*) 20 GHz STABILIZED OSCILLATOR IN MICROSTRIP B.B. van ABSTRACT. Possible systems for stabilization of a solid state microwave oscillator using a high Q-resonator, as the reaction and the transmission systems (including the Kurokawa system) are considered from a common theoretical point of view. This is achieved by using the

DESIGN AND APPLICATIONS OF SOLID STATE MICROWAVE AMPLIFIERS John MAGARSHACK ABSTRACT The design procedure will be analysed for a reflection type amplifier and a transistor amplifier from a circuit engineer's point of view. That is to say after an appropriate choice of the active device for the required application, the method of characterization for computer assisted design procedure will b



A NEW METHOD FOR ULTRA FAST SIGNAL PROCESSING AND PULSE GENERATION IN THE GBIT/S RANGE. Rudolf Schwarte ABSTRACT A new sampling line with series gates is suited for both fast signal recording and fast pulse generation up to 10 Gbit/s as found in experimental results. It consists of a delay line with equidistantly inserted switches (in practice Schottky diodes). The spatial lay line when voltage d

PIN-DIODE TRANSIENTS IN HIGH SPEED SWITCHING APPLICATIONS L. Szabo x, K. Schunemann x, F. Sporleder xx ABSTRACT: In guided millimeter-wave communication systems with high bit-rate the PCM is done in a reflection-type phase modulator with pin-diode. In this contribution the influence of the pin-diode switching transients on the modulator behaviour is studied both, experimentally and theoreti
