1KW Wireless Digital TV Broadcast Transmitter

1KW Wireless Digital Tv Broadcast Transmitter

The TV Transmitter is mainly composed of a TV modulation unit and an RF power amplification unit. Among them, the TV modulation unit uses the new FPGA + DDS to realize the software TV modulation function, while obtaining superior technical indicators while ensuring reliability and performance consistency; the RF power amplification unit uses international high-quality high-power field effect transistors, Analog/Digital Compatible, stable and reliable.

1000W Digital TV Transmitter is a high-standard, broadcast-level all-solid-state Compact design analog TV transmitter. It uses a new software radio technology to achieve the TV modulation function; the use of international high-quality LDMOS high-power field effect tube to achieve radio frequency amplification, the output power can be 1000W.

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.
