RUSHFPV 1.2G 1.3G 4W Analog Video Transmitter Module VTX with Antenna for FPV 7-30V Input Built-in IRC-TRAMP Protocol -Description: RUSHFPV 1.3G 4W V2 VTX video transmitter provides long-distance signal transmission with up to 4W of power and adjustable output power levels. It supports 16 channels in the range of 1080-1360MHz with precise PLL frequency stabilization, which eliminates frequency drift. The built-in bandpass filter minimizes harmonic interference, improving compatibility with navigation equipment. The aluminum housing with three layers of protection and active cooling ensures efficient heat dissipation and stable operation. Supports control via IRC Tramp protocol for easy parameter settings. Utilizes an RHCP polarization antenna with 1.7dBi gain for a stable signal. It is compatible with 7-30V power supply, which expands integration options. -Features Designed for long-range flights, transmitting power up to 4W and providing multi-level adjustment Supports 16 channels in the frequency range 1080-1360MHz Efficient PA and power calibration to ensure power consistency across all channels Tuned digital PLL circuit, chip-level integration, no frequency drift Built-in bandpass filter to reduce harmonic interference for navigation equipment Triple-layer aluminum alloy shell and large centrifugal fan provide sufficient heat dissipation to ensure stable transmit power output -Specifications --VTX Output power: PIT/25mW/200mW/1000mW/4000mW Frequency range: 1080-1360MHz Number of channels: 16 Input voltage: DC 7-30V Frequency accuracy: ±200KHz S/N (for ±3MHz): >70dBc Modulation type: FM Frequency adjustment: PLL Video input level: 1±0.2V p-p Frequency stability: ±100KHz Control protocol: IRC Tramp Antenna port: SMA 50 Ohms Operating temperature: -10℃~+70℃ Module dimensions: 44*29*15mm Weight (without antenna): 25.4g --Antenna Polarization: RHCP Operating frequency: 1200-1300MHz Gain: 1.7dBi VSWR (VSWR):
