产品概述

The 3.3G 4W VTX FPV video transmitter is designed for analog FPV video systems requiring 3060–3495MHz frequency coverage and 64 available channels. It supports FM modulation, PLL frequency control and IRC Tramp protocol control.

Selectable output power includes PIT, 25mW, 200mW, 1W and 4W. The transmitter uses a 50-ohm SMA antenna connector and accepts DC 7–30V input for 2S–8S power systems.

The module has a typical video input level of 1V ±0.2Vp-p, an S/N ratio above 55dBc, and a typical frequency precision of ±200kHz. Its dimensions are 44 × 28.6 × 14.7mm and its weight is 25.3g.

01- Ultra long range 4W output – 4000mW-class high power analog VTX with PIT/25mW/200mW/1W/4W selectable output and PIT mode capped at 1.4W for bench testing.
02- 64 channels, 3060–3495MHz – full BAND C + BAND d coverage for long range FPV without 5.8GHz congestion.
03- IRC Tramp + SmartAudio control – set power and channel from your FC/OSD or radio, no manual button hunting in flight.
04- Wide 7–30V (2–8S) input – power straight from the flight battery, no extra BEC or regulator needed.
05- 25.3g lightweight with fan + heatsink – stays cool and stable at sustained high power on long range builds.
06- FM / PLL with S/N > 55dBc – clean analog image over ultra long distance, rated -10℃ to +70℃.
