ABSTRACT:
A microwave system provides signals of two separate microwave frequencies, designated F.sub.(1) and F.sub.(2), alternately or simultaneously to a common coaxial transmission line by combining the outputs of two microwave frequency oscillators of frequencies F.sub.(1) and F.sub.(2). Each oscillator contains a waveguide output with which is associated at least one means, such as a resonant iris, for passing microwave energy of the oscillator's design frequency and for reflecting microwave energy of other frequencies, such as the different frequency of the other oscillator. A waveguide type transmission line is provided having first and second input ends and which line is of a length so as to be nonresonant at either of the two oscillator frequencies, F.sub.(1) or F.sub.(2). Each oscillator is coupled to a corresponding one of the two input ends of the waveguide. The waveguide is of a length in which signals of frequency F.sub.(1) form a field maxima at a certain location along the waveguide and in which signals of frequency F.sub.(2) form a field maxima along the waveguide at essentially the same said location. A microwave energy coupling probe is positioned in the waveguide at the location thereby defined to extract the microwave energy from the waveguide.
