NXP Semiconductors today announced new solid state RF cooking modules to accompany its popular RF cooking components portfolio. The new module is designed to help engineers rapidly build innovative RF cooking appliances that can achieve a better way of highly efficient, uniform heating, adaptability and consistency of the cooking process than conventional radiant or convection methods.
This new RF cooking module offering includes NXP's MKW40Z Kinetis microcontroller (MCU) with a 2.4 GHz RF signal generator, MMG3014 InGap HBT pre-driver, LDMOS MHT1008 driver and MHT1004 final stage amplifier into a single, integrated closed-loop module. Flexible software API commands are provided to simplify cooking appliance control system programming to enable new cooking features and capabilities.
The solid-state RF cooking module is a trusted development platform for cooking appliances that goes beyond simple device evaluation to supplement OEM engineering expertise. It features a comprehensive embedded design that allows appliance developers to easily transition to high-volume manufacturing of solid-state heating solutions.
Equipping manufacturers with RF cooking reference modules is crucial for this emerging appliance market. Demand is increasing for intelligent, secure, connected cooking appliances that will help tie together e-commerce food sourcing and end-point consumer use. This growth in demand can be attributed to consumer preference for convenient food preparation, but with higher quality and nutrition.
