1000W Digital Transmitter

1000W Digital Transmitter for Wireless Transmission Link

Wireless TV Digital Transmitter belongs to UHF band series transmitter, which is a kind of product(meet euro-standard) that specially designed to supply common or pilot frequency coverage and subsidiary station by consuming small and medium power for terrestrial digital TV transmission.

The series transmitter has optional power level from 10W to 500W, indoor type and outdoor type can meet with different users, and support multiple modulation modes, eg. DTMB, DVB-C, DVB-S/S2, DVB-T/DVB-T2, ISDB-T/ISDB-Tb and etc.. It is applicable to built-up areas, basement, tunnel and remote mountainous areas.Its main advantages include installation convenience and simple process in debugging and maintenance, etc. And in any combination of multiple antenna-feeder system it can supply local coverage and subsidiary station of wireless digital signal in the blind area. In addition to being widely used in domestic all-level television stations and network companies, it has exported in bulk to places like southeast Asia and Africa.

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 1000W transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.
