Product overview
The Kimpok AL3306 provides an FPV video transmission component for long-range drone installations. It operates across 3060-3495MHz with 64 channels and FM modulation, offering selectable PIT, 25mW, 200mW, 1W and 6W output settings. Its RF architecture combines a power amplifier, power calibration and digital PLL frequency control. This is a transmitter module for integration into a drone system; the described configuration centers on video transmission hardware, with an SMA 50 Ohm antenna interface and a specified video input level of 1V±0.2Vp-p typical.
The module measures 44 × 28.6 × 14.7mm and weighs 25.3g, giving integrators defined packaging dimensions and mass for installation planning. A three-layer aluminum alloy housing and large centrifugal fan form its cooling arrangement. Electrical integration requires DC 7-30V (2-8S), while the operating temperature range is -10°C to +70°C. Typical frequency precision is ±200KHz, and the specified signal-to-noise ratio exceeds 55dBc for ±3MHz. These electrical, signal and temperature requirements define the stated integration limits.
Configuration is available through a single button with integrated RGB indication or through a flight controller using the DATA connection and IRC Tramp control protocol. Blue identifies band settings, red identifies channel settings and green identifies power settings. A long press opens configuration, releasing at the relevant color selects the function, and short presses change its value. During normal inactivity, cyclic LED blink counts indicate transmitter status; a continuously illuminated green LED identifies PITMODE. The selectable power levels allow the transmission setting to be adjusted within the module's specified options.
