Power amplifiers of the Class D RF variety are renowned for their exceptional efficiency. By only activating the power transistors while the input signal exists, there is an ability to function with such efficiency. They are therefore perfect for battery-constrained applications like wireless sensors and mobile devices. It takes a lot of work to use mathematical modeling in MATLAB to create a Class D RF power amplifier. When designing the amplifier, its output capacity, energy usage, and resilience to disturbance and disruption must be considered with diligence, as these specifications will significantly impact the performance. Modeling the amplifier mathematically in a complex design process served as the essential first stride. This model can be used to mimic the amplifier's performance in various scenarios. The prototype can also simulate the amplifier's performance in various scenarios. The design of the amplifier can also be optimized using the model to meet the required criteria. Implementing the amplifier in MATLAB is the next step after creating the mathematical model. The MATLAB Simulink environment can be utilized to accomplish this. Electronic circuit models are simple to develop and simulate because of Simulink's graphical user interface. Testing whether the newly designed amplifier meets all specifications through a rigorous evaluation process represents the final stage in successfully completing the engineering design workflow. A power meter and an RF signal generator can be used to do this. The test outcomes can be used to confirm that the amplifier satisfies the required requirements. It is difficult yet possible to create a Class D RF power amplifier using mathematical modeling in MATLAB, an enjoyable task. Engineers can create effective and dependable Class D RF power amplifiers that satisfy the requirements of their applications by using the procedures described in this abstract.
