EW
Power amplifiers play a crucial role in Electronic Warfare (EW). In electronic warfare, power amplifiers are used to enhance the power of interference signals to interfere with or deceive enemy radar and communication systems, thereby reducing their combat effectiveness. Power amplifiers may be used to enhance the sensitivity of receivers in order to better intercept and analyze enemy electromagnetic signals, providing intelligence support for decision-making. The design and performance of power amplifiers are crucial for the effectiveness of electronic warfare systems. They must be able to work under extreme conditions such as high temperature, low temperature, high humidity, vibration, and shock, while maintaining high efficiency and reliability. With the development of technology, power amplifiers are becoming increasingly efficient, compact, and multifunctional to meet the constantly changing needs of modern electronic warfare.
