Description:

 

• 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 100W transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.
