I. Product Positioning: Precise Coverage of Key Interference Frequency Bands
This module is a high-performance signal shielding core component specifically designed for anti-FPV (First-Person View) drones. It focuses on the 2900-3100 MHz golden interference frequency band. This band is not only commonly used for image and data transmission signals in some consumer and industrial drones, but it is also highly correlated with the operating frequency bands of key radio frequency systems such as weather radar and maritime navigation. By precisely suppressing signals in this band, the communication link between the drone and the pilot can be effectively cut off, forcing the target to return, make an emergency landing, or hover, thus curbing the risk of "black flights" at the source. II. Core Technology: GaN Material Enables a Leap in Performance
Utilizing third-generation gallium nitride (GaN) semiconductor technology, GaN achieves three major breakthroughs compared to traditional LDMOS devices:
* **Power Density and Efficiency Leap:** GaN material boasts a power density of 10W/MHz, more than three times that of silicon-based devices. A stable 50W output power can create an ultra-wide-area interference field, effectively protecting against interference up to 5 kilometers in open environments. Furthermore, energy conversion efficiency is significantly improved, reducing continuous operation power consumption.
* **Extreme Environment Adaptability:** Integrated ceramic tube packaging and a high-efficiency heat dissipation structure, combined with a high VSWR protection design using ferrite isolators, enable stable operation across a wide temperature range of -30℃ to 60℃. It is impervious to harsh environments such as heavy rain and sandstorms, while also possessing strong open-circuit protection capabilities to prevent device damage caused by signal reflection. Signal suppression accuracy: Equipped with digital predistortion (DPD) technology to compensate for signal distortion, the frequency band flatness is controlled within ±0.5dBm, ensuring that the interference signal accurately covers the target frequency band and does not spill over to surrounding frequency bands, reducing the impact on legitimate communications.
