DMKR 3.3G 4W 16CH FPV Analog VTX

Overview

This 3.3GHz analog video transmitter is developed for long-range UAV video transmission systems, with a focus on high-power RF output, system stability, and flexible integration.

With in-house development and continuous iteration, the design supports customization and system-level integration, making it suitable for OEM and ODM projects across different UAV platforms.

RF Performance

The transmitter operates within 3170–3470MHz and provides 16 selectable channels for flexible frequency deployment.

With adjustable RF output power up to 4W (25mW / 2000mW / 4000mW), it supports both low-power testing and high-power transmission scenarios.

Compared to lower power variants, the increased RF output is suitable for applications requiring stronger signal coverage or higher transmission stability.

Power and Integration

The module supports DC 7–36V input and is compatible with 2–8S battery systems, enabling direct integration without additional voltage regulation.

IRC Tramp protocol is supported for remote adjustment of frequency and power through flight controller or OSD interface.

Standard 6P interface design simplifies system integration for power, video, and control signals.

Operational Notes

• Antenna must be installed before powering on

• Ensure sufficient cooling during high-power operation

• Verify correct voltage input before connection

• Avoid improper wiring to prevent module damage
