ABSTRACT:
A microwave oscillator/power combiner incorporates two microstrip transmission lines, each coupled electromagnetically to an output transmission line. Each of the microstrip transmission lines incorporate active diodes such as IMPATT or GUNN diodes which generate RF energy when acted upon by a DC voltage. The output transmission line is coupled to ground to allow the output end of the transmission line to be adjacent to the active diodes. The two microstrip transmission lines are coupled to a high Q tank circuit through a Wilkinson power divider. The high Q tank circuit is preferably a dielectric resonator. The oscillator may be cascaded to increase power output.
