The implementation of both approaches highly depends on the support of power amplifiers. Electronic Jamming: Power Amplifiers Determine the "Coverage Capability" of Jamming The core principle of electronic jamming is to block the control links (2.4GHz/5.8GHz) and GNSS navigation links (GPS/Beidou/GLONASS) between drones and their operators by emitting high-power electromagnetic waves of specific frequency bands. This forces the drones to enter the "lost-connection protection mode", resulting in automatic return, hovering in place, or forced landing. In this process, the role of the power amplifier is crucial: Enhancing the jamming coverage radius: The power amplifier can amplify the power of the basic jamming signal generated by the countermeasure module several times or even dozens of times, significantly expanding the jamming range. For example, in large-area protection scenarios such as airports, high-power amplifiers can increase the jamming coverage radius from hundreds of meters to several kilometers, achieving comprehensive protection of the airport's clear zone. Strengthening the signal penetration capability: In complex environments (such as building obstacles and electromagnetic noise interference), the power amplifier can enhance the anti-attenuation capability of the jamming signal. This ensures that even when there are obstacles in the signal propagation path, the normal communication and navigation signals of the drone can still be effectively suppressed. Ensuring the stability of multi-target jamming: When multiple drones conduct "unauthorized flights" in the airspace simultaneously, the power amplifier needs to provide a continuous and stable power output for the jamming signal. This prevents some targets from "escaping" the jamming due to insufficient power, ensuring the synchronous disposal capability of the countermeasure module for multiple targets. As a key component supplier for anti-drone defense systems, Fengqing Instruments has launched the FQPA series of power amplifier modules. With the core mission of "providing reliable radio frequency power output for government-authorized anti-drone systems", these modules have excellent performance and are suitable for countermeasure needs in multiple scenarios, making them the preferred equipment for countermeasure modules. This series of products includes two types of GaN HEMT power amplifiers: ceramic-packaged and plastic-packaged, and demonstrates outstanding advantages in wide frequency coverage, power output, and environmental adaptability. 1. Core Performance Advantages, Suitable for Complex Countermeasure Scenarios The FQPA series of power amplifier modules have multi-dimensional performance highlights, accurately meeting the strict requirements of anti-drone systems for power devices. In terms of frequency band coverage, the product can cover the range of 400MHz-6200MHz, which fully includes the mainstream remote control frequency bands of drones (such as 2350-2550MHz), satellite navigation frequency bands (such as GNSS-related frequency bands), and the 5100-5950MHz frequency band commonly used for image transmission. A single module can achieve jamming coverage for multiple types of drones without the need for frequent device replacement, improving the operational efficiency of the system. In terms of power output, the series of products offer flexible options, covering from 20W basic power to 200W high-power models, with clear distinctions between power types and specific scenarios: Among the plastic-packaged models, the basic model of the product with a 200MHz bandwidth in the 800-2550MHz frequency band has an output power of 20W, and the enhanced model can reach 30W. The model with a 200MHz bandwidth in the 400-2550MHz frequency band has a Continuous Wave (CW) output power of up to 50W. The ceramic-packaged models have even stronger performance: the product in the 200-390MHz frequency band has a CW output power of up to 100W, and the 800-2500MHz frequency band with a 200MHz bandwidth even offers a 200W high-power CW version, which can meet the strong suppression needs in long-distance and complex electromagnetic environments. For example, in border patrol scenarios, models with a power of 100W and above can achieve jamming coverage in a range of several kilometers, effectively preventing the intrusion of illegal drones; in the protection of airport clear zones, 50W models can cover an area of 3-5 kilometers around, accurately responding to "unauthorized flight" threats at medium and short distances. At the same time, the product optimizes linearity through advanced pre-distortion technology, improving the out-of-band spurious emission suppression capability by more than 30%. This minimizes interference to surrounding legal communication equipment and complies with international electromagnetic compatibility standards (such as EN 301 489-1). It supports TTL level or high-speed Serial Peripheral Interface (SPI) control, achieving nanosecond-level (

However, the accompanying security challenges cannot be ignored. From illegal aerial photography and commercial espionage to potential malicious attacks, drones have become a pressing security issue that demands resolution—and anti-drone technology has emerged as a response. To address the security and privacy risks arising from the widespread use of drones, a coordinated system of anti-drone products is essential. An integrated solution that combines multiple technologies is known as an anti-drone system. Its core concept is "Detect - Identify - Neutralize," ensuring timely and effective response to drone threats. 1. Detection and Identification All countermeasures begin with accurate perception of the threat. Modern anti-drone systems typically integrate multiple detection technologies to form an invisible defensive network. Radio Frequency (RF) Detection: This is one of the most common and effective detection methods. By capturing the radio signals transmitted between a drone and its controller, the system can quickly locate the drone and even identify its model and the controller’s position. Radar Detection: Radars specifically designed for low-altitude, slow-moving, and small targets can detect and track drones over a large area around the clock, unaffected by weather or light conditions. Electro-Optical (EO) Detection: High-definition cameras and infrared thermal imagers provide visual confirmation. Especially at night or in harsh weather, infrared thermal imaging can clearly detect the heat signature of a drone. Acoustic Detection: High-sensitivity microphone arrays monitor the unique acoustic signature of drone propellers, providing supplementary information to the system. These technologies complement each other, ensuring no drone can escape detection. 2. Jamming and Suppression (Soft Kill) Once a drone is identified as a threat, the system immediately activates "soft kill" measures— the most commonly used countermeasures in civilian and commercial scenarios. This method disables drones through non-physical means, avoiding collateral damage that might result from a crash. Radio Frequency Jamming: The system emits high-power jamming signals to cut off communication between the drone and its controller. Once the drone "loses contact," it usually follows pre-set protocols to either return to its take-off point automatically or make an emergency landing, allowing for safe neutralization. Navigation Signal Spoofing/Jamming: This involves jamming the drone’s navigation signals (such as GPS or Beidou) or transmitting false signals, preventing the drone from achieving precise positioning. This causes the drone to deviate from its route, hover in place, or lose control due to navigation failure. These technologies aim to resolve threats "peacefully" and are the preferred solutions for locations such as airports, prisons, and large-scale events. 3. The Final "Line of Defense": Physical Destruction (Hard Kill) For military or extreme threat scenarios, physical destruction is a necessary option. Interception Net Capture: Specialized interception drones can launch a large net to directly capture the intruding drone. This method preserves the drone intact, facilitating subsequent evidence collection and analysis. High-Energy Laser Weapons: An emerging and highly effective countermeasure. High-energy laser beams can instantly burn through key components of a drone, causing it to crash immediately, with relatively low operational costs. Directed Energy Weapons: These use microwave or high-energy electromagnetic pulses to directly destroy the electronic equipment inside the drone, rendering it completely non-functional. The security and privacy threats posed by drones are becoming increasingly complex and diverse, placing higher demands on anti-drone technology. By focusing on product technology innovation, enterprises can enhance detection and countermeasure capabilities, providing technical support for combating future drone threats and safeguarding airspace.
