Product Description
For FPV pilots, drone operators, and wireless professionals pushing the limits of range and video quality, 5.8GHz remains the gold standard for video transmission—delivering the bandwidth needed for HD video with manageable antenna sizes and global availability. This 5.8GHz 40W RF Power Amplifier delivers a commanding 46dBm (40W) of clean output power with 40dB gain across the full 5.725-5.85GHz ISM band, covering all standard FPV channels including Raceband, E band, F band, and more. Leveraging advanced GaN (Gallium Nitride) technology for exceptional efficiency and thermal performance, it operates on a 28V DC supply with just 3.2A current draw at full output. Housed in a rugged aluminum enclosure with SMA female connectors, it's engineered for pilots and professionals who demand the absolute pinnacle of video link performance.

Key Advantages
40W of GaN-powered output pushes 5.8GHz video links into an entirely new realm of performance. The 5.8GHz band delivers excellent bandwidth for HD video transmission, but its higher frequency comes with increased path loss compared to lower bands. With 40W (46dBm) of clean output power, this amplifier provides up to 6-10x the effective range of standard 1W VTX systems—delivering significantly more power than lower-wattage versions for the ultimate in range and penetration through trees, buildings, and other obstacles. For pilots chasing extreme distances or operating in RF-dense environments, 40W delivers the ultimate competitive edge.
Advanced GaN technology is the backbone of this amplifier's exceptional performance. Gallium Nitride delivers higher efficiency, better thermal performance, and greater power density than conventional designs. The result is 40W of clean output in a package that weighs just 210g—an extraordinary power-to-weight ratio unmatched in this power class.
The 40dB gain transforms low-power VTX outputs (as low as 10mW) into full 40W transmission with consistent, predictable linearity. Current draw remains efficient at just 3.2A—allowing you to achieve maximum range without prematurely draining your drone's battery.
Thermal performance is engineered for sustained operation at extreme power levels. The rugged aluminum housing provides efficient passive cooling, while the 132×53×17mm form factor and 210g weight offer improved thermal dissipation for reliable 40W continuous transmission—making it ideal for both drone mounting and ground station use.
Optimized for the full 5.725-5.85GHz ISM band, this amplifier covers all standard FPV channels including Raceband, E band, F band, and more. When 10W, 20W, or even 30W isn't enough, 40W delivers the ultimate performance for those who refuse to compromise on range and reliability.
