I. Introduction: Frequent “Rogue Flights” Highlight the Urgent Need for Long-Range Suppression
In recent years, the rapid rise of the low-altitude economy and the drone industry has led to widespread use in logistics, emergency rescue, and security inspection. However, illegal or unauthorized drone flights have become increasingly common. According to data from China’s Ministry of Public Security, over 5,200 illegal drone flight incidents were recorded nationwide in 2024, with approximately 38% occurring in sensitive airspaces such as airports, power plants, and military zones.
Traditional short-range jamming devices may perform adequately in open areas, but in urban environments with complex electromagnetic conditions, their signals attenuate quickly, coverage is limited, and response times are slow—making it difficult to achieve precise long-range suppression. Against this backdrop, the long-range UAV suppression power amplifier module has become the “new nerve center” of drone electronic countermeasure (ECM) systems and a crucial component in building secure low-altitude defense networks.
II. Pain Point Analysis: Traditional Countermeasure Systems Struggle in Multi-Frequency Environments
Current mainstream anti-drone systems typically rely on directional antennas and multi-band jamming signal sources, yet they still face three major limitations:
- Limited Suppression Range (<2 km): Most amplifier modules output less than 50W, making them ineffective in achieving stable suppression across complex terrains.
- Poor Frequency Adaptability: Conventional modules primarily focus on 2.4GHz and 5.8GHz bands, offering limited support for emerging industrial frequencies above 6GHz.
- High Latency and False Alarm Rates: Systems relying on manual tuning and low-speed detection algorithms cannot effectively handle drones that use automatic frequency hopping or coordinated swarm flight.
For instance, during a major sporting event in 2024, multiple drones entered a restricted zone from approximately 3.5 km away. Although portable jammers were activated, they only succeeded in disabling a few low-power drones. The event was interrupted for seven minutes—exposing a critical “long-range blind spot” in existing defense systems.
III. Technical Highlights: Dual Engines of High-Power Amplification and Intelligent Modulation
The core competitiveness of the long-range UAV suppression power amplifier module lies in three technological breakthroughs—long-range capability, high output power, and intelligent adaptation.
- Ultra-Wideband High-Power Output
- Covers 100 MHz–6 GHz, compatible with Wi-Fi, GNSS, LTE, 5G, and custom drone frequencies.
- Single-channel output reaches 100W–200W, supporting multi-channel parallel output for a maximum suppression distance of up to 8 km.
- Intelligent Signal Modulation Algorithm
- Utilizes DDS (Direct Digital Synthesizer) signal generation technology combined with AI-based modulation recognition.
- Automatically matches the target drone’s control and video transmission signals, achieving millisecond-level recognition and response.
- In testing environments, achieved a 96.3% interference success rate against DJI and Autel drone series.
- Modular Cooling and Protective Design
- Integrated heat conduction channels and magnesium-aluminum alloy casing allow operation from -30°C to +65°C.
- Rated IP65 for waterproof and dustproof protection, suitable for humid and sandy environments.
- Compatibility with Mainstream Countermeasure Systems
- Can link with radar and electro-optical detection modules via RS485 or Ethernet interfaces, enabling automated identification and remote suppression in a closed-loop defense system.
IV. Application Cases: From Border Control to Integrated Urban Air Security
- Border Anti-Infiltration Missions:
In 2025, a border province deployed the long-range suppression module at fixed outposts for drone detection and suppression. Tests showed an effective coverage radius of 7.8 km with 720 hours of continuous, fault-free operation. - Large-Scale Event Security:
During the 2024 Asian Games in Hangzhou, security forces used the module with optical detection systems to monitor drones within a 2 km radius, successfully disabling 11 rogue drones by cutting off their control and transmission links. - Energy Infrastructure Protection:
Nuclear power plants and oil depots have deployed the module integrated with automated radar systems. Upon detecting drone proximity, the system automatically switches frequencies to suppress the target without affecting nearby communications.
