This TV transmitter is a high-standard, broadcast-grade integrated all-solid-state analog TV transmitter. It adopts new software radio technology to realize TV modulation function; it adopts international high-quality LDMOS high-power field effect tube to realize RF amplification, and the output power can be selected according to needs, which are 50W / 100W.

The TV transmitter is mainly composed of a television modulation unit and a radio frequency power amplification unit. Among them, the TV modulation unit adopts a new FPGA + DDS to implement software-based TV modulation function, which guarantees reliability and performance consistency while obtaining superior technical indicators; the RF power amplifier unit uses international high-quality LDMOS high-power FETs, and the Analog/Digital Compatible, stable and reliable work.

The whole transmitter uses a 19 "standard stainless steel case, which is suitable for TV stations of all levels.

● It adopts new FPGA + DDS technology to realize software-based TV modulation function, with superior performance, high reliability and good consistency.
● It adopts the integrated structure design, and the single-channel image sound combination type is easy to install and use.
● It has the functions of no video, excessive standing wave ratio, over power, over voltage, over current, and over temperature protection to reduce equipment damage.
● With intelligent network management and monitoring, with RS232 and TCP / IP communication interfaces.
● It’s using high-quality switching power supply, with over-voltage, over-current, under-voltage, over-temperature, short circuit, lightning protection and other protection measures, high efficiency, good voltage regulation range, strong ability to adapt to external power changes.
● It adopts high-quality high-flow axial flow fan, with good heat dissipation effect, keep the transmitter in a low temperature state, and extend the life of the transmitter.
