摘要：A microwave oven using a waveguide feed to deliver microwave energy from a magnetron source to an oven cavity, wherein a substantially reflectionless pha shifter is interpod in the waveguide for adjusting the electrical characteristics thereof to cau the magnetron to operate efficiently and safely. The pha shifter is dimensioned to match the impedance of the oven cavity and load to that required by the magnetron by adjusting the electrical characteristics of the waveguide so that such adjustment may be carried out without the need for changing the physical configuration of the oven or waveguide. The pha shifter is dimensioned to adjust the average impedance of the cavity and load when the cavity is heavily loaded to cau the magnetron to operate in its maximum power delivery region, and to adjust the aforementioned impedance under conditions of light load to cau the magnetron to operate in a safe region. The pha shifter, thus, not only aids in achieving maximum power delivery, but also rves to protect the magnetron.
