Image transmission systems are categorized by transmission frequency: 1.2GHz, 2.4GHz, and 5.8GHz. Since the 2.4GHz frequency is the same as the remote control frequency, interference may occur, and its use with FPV (Fast Moving Vehicle) is not recommended. Image transmission systems consist of a transmitter and a receiver. The transmitter is installed in the carrier unit and transmits information from the transmitter to the ground receiver via an antenna, where it is converted and displayed on the screen. The transmitter's power directly affects the transmission distance. Three factors influence the distance: transmitter power, antenna gain, and receiver sensitivity.
Boya Micro Image Transmission: A rising star in the image transmission industry, this innovative integrated PCB product differs from the (RF module + power module) stacked structure found in the market. Its market-tested performance is excellent, and its well-designed wiring effectively solves the ripple interference problem. The ultra-thin (0.6mm thick) PCB design tightly integrates the heat-generating chip and heat sink, eliminating the need for fan-assisted cooling. This allows heat to be directly transferred to the heat sink, preventing heat buildup on the chip, which can lead to power degradation and shorten its lifespan.
Chuangxin Technology Image Transmission: This is a long-established brand, but its quality and manufacturing control are not very good. There are design flaws, especially in chip heat dissipation (using thermal conductive film to conduct heat to the heatsink, but due to the low thermal conductivity of the film, a large amount of heat cannot reach the heatsink quickly and immediately). In addition, there are many counterfeit products from small workshops in the market, making it quite chaotic.
Other brands include Chuangxin Technology, Omway, and Eagle Eye, so the image transmission industry is highly competitive. Only innovation, quality, and service can win customers' favor.
