Temperature Uniformity of Germinated Brown Rice by a Rotating Tray for Microwave Heating

0.5kWatt 2.45 GHz GaN‐based microwave heating system design with active phase control

“…The conventional MW heating system receives power from a power supply, generates a signal using a magnetron having oscillator properties, and then applies it to the MW applicator through a waveguide. Since the magnetron oscillation times are different, the input phase of the magnetron at the MW heating system with multiple magnetron sources cannot be matched 11–17 …”

“…Since the magnetron oscillation times are different, the input phase of the magnetron at the MW heating system with multiple magnetron sources cannot be matched. [11][12][13][14][15][16][17] Figure 1 shows the proposed 2.45 GHz GaN (gallium nitride)-based MW heating system including overall configurations and antenna deployment. In Figure 1A, THE proposed system consists of two 2.45 GHz signal generators, two electrically controlled phase shifters, two 250-W GaN amplifiers, two metal patch antennas, and the MW applicator with heating material.…”
