Key Technical Features & Detailed Performance Parameters
High-Power Independent Dual-Band Amplification Solution
The VS-3.0 equips two fully separated 20-watt RF power amplifiers, which operate simultaneously on the 2400–2500 MHz (2.4 GHz) and 5000–5925 MHz (5.8 GHz) frequency bands without mutual signal crosstalk. The overall system output power reaches 43dBm, while the input power supports a wide adjustable range from 5dB to 27dB, allowing flexible matching with different types of drone remote controllers.
The transmission noise figure of the whole system is controlled within 2.0 dB or lower, which greatly reduces background noise interference and improves signal-to-noise ratio of both uplink control signals and downlink image transmission signals. The transmission delay is controlled under 1 picosecond, ensuring zero obvious lag of flight control and real-time aerial footage, which is critical for precision inspection and emergency response missions.
Directional High-Gain Antenna System & Long-Distance Reception
Matched directional antennas deliver adjustable gain of 12dB or 15dB with ±1dB tolerance. The beam width design differs for two frequency bands to balance coverage and signal concentration: the 2.4 GHz antenna features a horizontal beam width of 76 degrees and vertical beam width of 66 degrees for wide-area near-to-medium range coverage; the 5.8 GHz antenna adopts a narrow beam design with 26-degree horizontal width and 28-degree vertical width to focus long-distance signal transmission. Under line-of-sight conditions, the system can stably receive and transmit effective signals within a 2-kilometer radius in all directions.
Wide-Voltage Power Supply & Intelligent Power Display
The amplifier main unit supports dual standard operating voltages of 6–12V and 7.4V, with matching R600 portable power bank rated at 299Wh to supply continuous power. An integrated LCD screen is reserved on the equipment panel to display real-time remaining battery level, allowing operators to grasp power status at a glance and avoid sudden power failure during critical tasks. The standard N-K female connector is adopted for all RF interfaces, which offers stable impedance matching and convenient quick wiring with various coaxial cables.
Industrial-Grade Environmental Adaptability & Compact Structure
The whole machine has a solid integrated structure with overall dimensions of 330 mm × 300 mm × 70 mm and a total weight of 4.1 kilograms, easy to transport and install on site. It supports normal stable operation in an extreme temperature range from -35°C to +85°C, and can continuously work under working humidity up to 75% relative humidity, adapting to alpine cold regions, high-temperature desert zones, coastal humid areas and other complex outdoor environments.
