[0002] With the continuous advancement of science and technology, the demand for heat dissipation in electronic equipment is becoming increasingly stringent. This is especially true in microwave / millimeter wave systems, where all electronic equipment is stored or operated under certain environmental conditions. Temperature, a key climate factor, has a particularly significant impact on electronic equipment or systems. High and low temperatures, and their cycles, can significantly impact most electronic components, leading to component failure and, in turn, overall device failure. This is particularly true in high-power amplifiers. Data indicates that in transmitters, for every 10°C increase in junction temperature of power transistors, reliability decreases by 60%.

[0003] Based on the above, the inventors have discovered the following problem: when the current microwave power amplifier is in use, the temperature of the microwave power amplifier will gradually increase, so the microwave power amplifier needs to be heat-dissipated in a timely manner. However, the heat dissipation efficiency of the existing microwave power amplifier is low, which may cause the efficiency of the microwave power amplifier to decrease.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a microwave power amplifier with a heat dissipation structure is provided, in order to achieve the purpose of having greater practical value. Summary of the Invention
