Advantages and Disadvantages of solid state rf energy
This page covers advantages and disadvantages of solid state rf energy. It mentions solid state rf energy advantages (i.e. benefits) and solid state rf energy disadvantages (i.e. drawbacks).
Radio Frequency operates in 3 KHz to 300 GHz band. We have seen that it is used for wireless signal transmission and reception for data/voice communication.
RF energy is also used in controlled environment for heating application. This concept is being used in cooking appliances. We have seen magnetron based microwave ovens. Now-a-days solid state electronics based ovens are available. This is based on solid state RF energy.
solid state rf energy Advantages
Following solid state rf energy advantages are utilized in many applications
including cooking oven, lighting, medical (MRI, NMR) and automotive domains.
➨It offers low voltage drive and low power.
➨It has small form factor.
➨It provides control of frequency, power and phase of synthesized source. This creates even RF energy distribution in the closed cavity of the oven.
➨It offers high efficiency and high linearity.
➨It provides increased precision.
➨It offers semiconductor like reliability.
➨It provides excellent gain due to use of Power Amplifier.
➨It enables increased control due to use of RF synthesizer as excitation source. Frequency accuracy in ppm can be achieved. This leads to fast frequency hopping and tuning.
➨RF Energy Alliance is continuosly working towards standardizing solid state modules, components and interfaces. This will reduce the cost to greater extent.
➨Lifetime of device is enhanced.
solid state rf energy Disadvantages
Following are solid state rf energy disadvantages.
➨The initial investment to buy the solid state rf devices is higher.
➨It uses RF modules such as RF power amplifier and RF synthesizer. This requires skilled technicians to debug the issue in case the device goes faulty or encounter some issues. Hence cost of repair increases.
Conclusion: The benefits of solid state electronics based RF devices are numerous compare to the drawbacks and hence it is widely used for various applications in different domains. The popular applications include cooking oven, lights, tumor ablation, drying, ignition etc.
