Professional Broadcast FM Transmitter 50W series is a profesional FM stereo/Mono broadcasting transmitter. The advanced digital technologies,Digital Signal Processor(DSP), are used in the transmitters to get little size , high performance and high reliability. They are widely used for professional radio stations to transmit high quality FM radio programs.
More than that, the RS-CM1500W FM transmitter is now gradually showing its high-quality characteristics to the world, especially in the radio station equipment market.
200W Digital TV Transmitter incorporates multiple self-protected mechanisms, including high VSWR, over-temperature, over drive, over current, over voltage and under voltage. It supports Web based management and maintenance for remote status monitoring and controls, this can significantly reduce management time and operating expense (OPEX). By incorporating the latest technologies of RF delay and co-channel interference rejection, this system fulfills the needs for DTT coverage of SD and HD digital television programs. This is especially suitable for small-scale coverage and gap filling with complex terrains.

Overview:
This product is the all solid-state Single-channel TV Transmitter, it adopts professional TV exciter, and it can use the
single/duel exciter configuration, switching automatically.
This transmitter has a variety of linear and non-linear pre-correction function, carrier frequency offset, and precision bias
(with external precision reference source) function.
It can prefabricate and control the half-power output, and it has remote control telemetry interface.
The power amplifier used LDMOS FET, the analog and digital are both compatible, and it used high-quality switch parallel power.
The power amplifier and power supply are both used hot-plug devices.
The power loss and standing wave of the one-time synthesis power combiner is small.
The module of power amplifier display the working parameters in real-time.
The whole machine has the protection of over-current, over temperature, over power and over-standing wave ratio.
The master touch screen displays the working parameters of the whole machine and the module of power amplifier (PA) in real-time.
The 200W transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.
