Using RF Energy for industrial heating Unlike conventional heat sources used for industrial heating applications, RF energy allows for very controlled material heating using high frequency electromagnetic energy. Typical heating solutions may use infrared radiation or convection heaters to remove moisture. These solutions are effective, but inefficient with regards to the power used and the fact that they dry from the outside of a surface and slowly heat to the inside of the subject material. By contrast, RF energy heats the entire material. An excellent example is the domestic microwave oven used to heat and reheat food in households throughout…
RFMW announces design and sales support for a high-performance, mmWave power amplifier from Qorvo.
