NXP makes high-performance integrated module available

Posted By : Jordan Mulcare

NXP Semiconductors has announced new solid state RF cooking modules to accompany its popular RF cooking components portfolio. The 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 RF cooking module offering includes NXP's MKW40Z Kinetis MCU with a 2.4GHz 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.

The RF development module provides an inexpensive entry point that allows appliance designers to quickly and easily build tailored application prototypes that have best-in-class RF output power, efficiency, and gain.

The RF cooking module features include:

  • Fully functional, manufacture-ready design
  • 220 to 250W RF output power at 2.45GHz
  • Operation from 24 to 32V at 18A maximum
  • Greater than 60% efficiency
  • Communications interfaces (I2C, SPI or UART)
  • Compact size: approximately 75x95x30mm
  • Comprehensive sensing including measurement of forward and reflected power, current, voltage, and temperature
  • Coordinated power, phase, and frequency control
  • Even, distributed EM field
  • Flexible API interface to appliance control systemsHardware-based monitoring and safety fault/shutdown
  • Scalable RF power modules (250 W to 1 kW)

The RF module enables support for the full range of NXP RF cooking components including the MMG3014 pre-driver, MHT1008 driver, and MHT1004 final stage devices.
