Quasi-optical power combiner

Two novel and compact Q.O.P. combiners of (S.S.S.) in M.M.W band is described. This paper explains with emphasis the principle and the fabrication of the combiner.

Millimeter Wave Power Combiner Based on a Half-Open Resonator

Experimental investigations of quasi-optical power combiner based on a half-open resonator are described. Power and frequency characteristics have been studied for one or three diodes. It is shown that the positioning of the diodes is preferred over the center of the field spot along a resonator axis.

Millimeter wave quasi-optical power combiner

The results of an experimental research of the power combiner based on the half-open resonator (HOR) are presented in this work. The HOR represents half of the usual spherical OR, which is cut by a conducting plane along OZ axis. Therefore, the modes are excited on this, which does not contradict boundary conditions on a conducting plane of the HOR.

Investigation of the Gunn oscillator with barrel-shaped open resonator

In the given work we embarked an attempt to modify a design of the barrel-shaped open resonator (BOR) with the aim to place and to match to it the semi-conductor generating elements (Gunn diodes). We have shown by experiment, BOR with a narrow rectangular groove can successful be used as a resonance system of solid-state oscillators. Power adders of several solid-state sources can be constructed on its basis.

Gunn-Diode Oscillators and Amplifiers Based on the Barrel-Shaped Open Resonator

An open resonator with its constituent the barrel-shaped reflected surface is described. Millimeter wave-band oscillator and amplifier based on this resonator investigated. The power and frequency characteristics are presented. It is shown that this device can best be used as a regenerative amplifier.
