Key Specifications
H.265 low delay COFDM UAV downlink system

SG-TM308 is a new launch digital transmitter module from SAFE GUARD company which adopting of the latest COFDM modulation and H.265 video coding technology that support multiple IP input with triple video interfaces (HDMI/SDI/CVBS), and is capable for non-line-of sight (NLOS) transmission. It is highly integrated with ultra-linear digital predistortion RF design that set high-definition coding, digital modulation, full-band RF output in one and comes with narrowband(1MHz), low latency, transparent data long-distance transmission which can help you to achieve a long-distance wireless links required, especially for military, security, public security, and fire protection applications. It is widely used in high standard unmanned control system and intelligent control equipment for multi-channels video transmission.
