The global market for the ubiquitous microwave oven is huge. But with so many competing manufacturers, there’s high pressure for low prices. For consumers to pay more, microwave ovens must be reliable, energy efficient and packed with features that distinguish them from the masses. Consumer-driven benefits – faster cooking, enhanced cooking functions as well as straightforward cleaning and safety features – weigh in big. And there’s an enormous push to launch products as quickly as possible.

The latest solid state RF powered microwave oven solution from Infineon helps consumers achieve a better cooking experience. It offers precise cooking, improved food quality, greater consistency, selective heating, and versatile and complex cooking combinations.
Using the latest LDMOS, you can use one or several these 250W units to build a microwave oven with the desired power level. RF power transistors and architectures provide a full range of power control, phase shifting, and frequency adjustments, allowing microwave ovens to cook complex combinations. Also, 30V operational voltage improves safety and replaces the magnetron’s 4 kV power supply. These microwave ovens also enjoy a significantly longer product lifetime.
In line with the latest home appliance trends, the solution offers a reliable Wi-Fi interface with a high degree of sensitivity, strong signal and interference immunity, enabling users to enjoy the cooking experience and share it in the cloud.
