Compared with magnetron solution, the advantages of solid-state solution
    RF microwave solid state power amplifier device offers many advantages to heating application development: Controlling heat by high precision & closed loop mode. Solid state power amplifier device is much smarter than magnetron component, enabling previously-impossible mobility and compact design available for customers. The closed loop mode makes more intelligent kitchen heating appliances and coordinative cooking utensils available while coexisting with other wireless-connected home products. For instance, traditional magnetron oven adopting simple on-off control mechanism to keep energy inside oven chamber. Solid-state solution makes process control of energy to the load, as well as getting feedback or monitoring temperature & output power inside oven chamber available.

The comparison of magnetron and solid-state solution:
