제품 설명

Product Background

The widespread application of drones and the emergence of safety risks: In recent years, the civilian and military applications of drone technology have shown a "dual-track parallel" trend. From consumer-level aerial photography to logistics delivery, from border surveillance to precision strikes, drones have permeated every aspect of society and the economy. However, the popularization of technology has also given rise to the "black flying" chaos. In early 2025, a chemical industrial park in India suffered an explosion accident due to illegal entry of drones, causing significant losses; the Pakistani border defense forces repeatedly reported cross-border drone reconnaissance incidents, and traditional defense measures frequently failed, all of which posed a serious threat to low-altitude security.
The inevitable demand for anti-drone technology development: Anti-drone equipment mainly achieves countermeasures by interfering with, suppressing, or hijacking the communication links between drones and their operators. The anti-drone power amplification module, as the core component of the signal transmission system, its performance directly determines the countermeasure effect. In the early anti-drone equipment, due to the low efficiency of the power amplification module, there were problems such as insufficient power and single frequency band, making it difficult to cope with multi-drone cluster attacks and prone to being avoided by drone frequency hopping technology. Therefore, a more efficient power amplification module is needed to enhance the countermeasure capability.

The need for safety protection in specific locations: Airports, government facilities, military bases, nuclear power plants, etc., have extremely high safety requirements. Illegal entry by drones may lead to serious consequences, such as affecting flight take-offs and landings, leaking important information, and threatening the security of critical infrastructure. Anti-drone power amplification modules can enhance the output power of signal interference equipment, ensuring that the interference signal performs at its best in long distances and multi-frequency environments, providing strong protection for the low-altitude safety of these locations.
Promotion of related technological advancements: The application of new semiconductor materials such as gallium nitride (GaN) has provided technical support for the development of anti-drone power amplification modules. Compared to traditional silicon-based modules, GaN modules have significantly increased power density and improved heat dissipation efficiency, supporting long-term high-load operation. At the same time, the development of digital predistortion technology (DPD) and Doherty power combining technology also helps to improve the performance of the module, enabling it to better meet the requirements of anti-drone operations.
