2000W Analog TV Braodcast transmitter


Description:


Model :CZH518A-2000W
Product Name : 2000W tv Transmitter

This is 2000W tv anolog free air station for you if you want to build the UHF and VHF station frist time.It is the best choice.


Overview:


This Transmitter is a high-standard, broadcast-level all-solid-stateCompact designanalog 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 be2000W.

The TV transmitter is mainly composed of aTV modulation unitand anRF power
amplification unit. Among
them, the TV modulation unit uses the newFPGA + DDSto
realize the softwareTV modulation function, while
obtaining superior technical indicators while ensuring reliability and
performance consistency; theRF power amplification unituses
international high-qualityLDMOS high-power field effect transistors, Analog/Digital Compatible, stable and reliable.

The whole Transmitter adopts 19 "standard stainless steel case, suitable for all
levels of TV stations.


Features :

●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.
