Overview
The 6110MHz–7210MHz 6-7GHz FPV VTX 3W Power Amplifier is a high-performance video transmission solution designed for professional FPV drone applications, long-range UAV flights, and industrial UAV video systems. Covering the 6–7GHz frequency band, it provides 64 selectable channels and adjustable power output from 25mW to 3W, allowing pilots to tailor transmission strength to their flight needs. With lightweight construction (25.85g), compact dimensions (53mm x 28.85mm x 16mm), and robust aluminum heat sink with an active cooling fan, the VTX ensures stable operation even in high-power, long-duration flights.
The module is compatible with standard FPV receivers operating in the 6–7GHz band and supports IRC Tramp protocol for remote configuration through compatible flight controllers. It also includes features like PIT mode for safe indoor testing, automatic overheat protection, and multiple frequency bands for flexible channel selection.
This VTX is ideal for FPV racing, freestyle flying, professional UAV surveys, and any scenario where high-quality, reliable video transmission is required over medium to long distances.
