Product Description
FPV pilots, drone operators, and wireless system integrators know that 5.8GHz is the backbone frequency for video transmission—offering exceptional bandwidth for HD video while maintaining manageable antenna sizes. This 5.8GHz 20W RF Power Amplifier delivers a commanding 43dBm (20W) 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. Operating on a 24V DC supply (customizable to 28V) with just 2.5A current draw at full output, it features a rugged aluminum housing and SMA female connectors—engineered for reliable performance in drone-mounted, ground station, and field deployment scenarios where maximum video range and penetration are required.

Key Advantages
20W of clean output power elevates 5.8GHz video links from solid to exceptional. 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 20W (43dBm) of clean output power, this amplifier provides up to 5-8x the effective range of standard 200mW-1W VTX systems—delivering double the power of the 10W version for significantly enhanced range and penetration through trees, buildings, and other obstacles.
The 40dB gain transforms low-power VTX outputs (as low as 10mW) into full 20W transmission with consistent, predictable linearity. Current draw remains efficient at just 2.5A—allowing you to achieve maximum range without prematurely draining your drone's battery, while delivering significantly more output than lower-power alternatives.
Thermal performance is engineered for sustained operation at higher 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 20W continuous transmission—making it ideal for both drone mounting and ground station use.
Wide voltage tolerance (24V standard, customizable to 28V) ensures compatibility with 6S LiPo batteries, ground station power supplies, and various DC sources. With SMA female connectors on both input and output, integration with existing antennas and RF chains is completely plug-and-play.
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 isn't quite enough for your long-range ambitions, 20W delivers the extra punch that separates good video from rock-solid, long-range performance.
