Product overview
The DMKR 3.3G 3W 16CH FPV Analog VTX is an analog first-person-view video transmitter. It is built for long-range UAV video links and for custom RF applications in specialised frequency environments. It transmits at 3.3GHz on 16 channels and is rated at 3W. The emphasis is on high-power RF output, system stability and flexible integration. It is a transmitter component, not a flight platform or an airframe kit. The design is developed in-house and supports customisation and system-level integration, so it suits OEM and ODM projects on different UAV platforms.
The module sends both video and audio. Audio rides on an integrated 6.5MHz sub-carrier. The unit works with standard PAL and NTSC camera systems and has wiring support for a combined AV signal input. A standard 6-pin interface carries power, video and control signal connections, and the control protocol is IRC-Tramp. The input rating is given two ways: 7–36V DC (2–8S LiPo) and DC 6–36V. The 7–36V range falls within both figures. The module measures 37.7×36.1×11mm, weighs 16g, mounts on a 30.5×30.5mm hole pattern and uses an SMA antenna connector.
The operating limits matter for installation. Fit the antenna before powering on. Provide enough cooling when the module runs at high power. Check that the input voltage is correct before connecting it, and avoid improper wiring, because wiring errors can damage the module.
