With its potential to transform applications such as the microwave oven, RF heating technology with high power and high efficiency is receiving increased attention. Until now, magnetron technology has been the mainstream system for generating RF energy, but the introduction of Solid State technology has recently enabled manufacturers to achieve even greater functionality in microwave ovens. With Solid State technology, uniform heating, select heating, downsizing and lightening, high reliability and long life are all made possible.

When it comes to high-power RF energy application, our “GQM series” high-Q capacitators are the best option. As shown in the below figure, the GQM series is suitable for both high-frequency and high-power applications, and have also performed well in cellular base stations. In addition, these capacitors are suitable for use in Solid State microwave ovens.
GQM Series Line-Up
High Q/Low ESR is realized in a high-frequency area by using low-loss ceramic material and copper inner electrodes.
Self-heating for RF power can be reduced because the GQM series has higher Q/lower ESR characteristics in high frequencies when compared with general capacitors. Therefore, high-power capacity can be achieved.
