Solid State RF Powered Oven Solutions

In 1970s, the RF heating brought convenient cooking experience, by using electromagnetic radiation in microwave spectrum, consumers can reheat leftovers, defrost frozen foods, etc.

Solid State RF Powered Oven solutions from Infineon

With the latest solid state RF powered oven solution from Infineon, consumers will reach a higher level experience of cooking, families can enjoy the more precise cooking, improved food quality, greater consistency in quality of cooking, selective heating, and versatile and complex cooking combinations.

Using the latest LDMOS, manufacturers can use one or several these 250 W units to build a microwave oven with the desired power level. The RF power transistors and architectures will provide a full range of power control, phase shifting, and frequency adjustment allowing microwaves to cook complex combinations. Also, the safety improved due to 30 V operational voltage will replace the magnetron’s 4 kV power supply, and the product lifetime is significantly greater.

Aligning with home appliance moving trend, the solution has the reliable WIFI interface, with the sensitivity, strong signal capability and interference immunity, users can enjoy the cooking experience and can share the experience in Cloud community.

Infineon offers a comprehensive portfolio to address a broad range.
