Product Description

  50W~100W Digital TV Transmitter
Overview
This transmitter is composed of various standard terrestrial digital TV exciter modules (DTMB, ISDB-T, DVB-T/T2, ATSC or full standard) using FPGA+DDS technology, and is a terrestrial digital TV transmitter that complies with a single standard or full standard.
This product adopts a powerful 4-core ARM microprocessor+FPGA+SOC joint control system to ensure excellent performance and stable operation. Adopting a silky graphical interface, users can operate the transmitter like a mobile phone, realizing the design concept of operating this product without reading the user manual.
This product uses AMPLON's latest generation of high-efficiency, high linearity, and anti standing wave ratio LDMOS tubes as power amplifier components, equipped with a highly reliable power amplifier power supply with over 100% redundancy, striving to implement the design concept of extremely high reliability.
Product model: 50W and 100W.    ZHC518D-50W, ZHC518D-100W
 

Features
A high-performance incentive module that meets a single standard or a full standard, achieved through FPGA+DDS technology.
The 4.3-inch color touch screen displays the main parameters and operating status of the exciter module, power amplifier, single frequency network timing device, etc., and various parameters can be set through the screen.
All solid state digital TV transmitter, using the latest generation of high linearity, high efficiency, and high standing wave ratio resistant LDMOS transistors.
Adopting Huawei's high-efficiency hot-plugin switch power supply for front-installation, easy for maintenance and repair.
Combined with the adaptive pre-distortion correction technology of the incentive module, high efficiency for the entire transmitter.
Equipped with a built-in timer for automatic power on/off, it can achieve timed automatic power on/off.
Set emergency power button, which can be turned on and off with one click.
Visualized human-machine interface, operate the transmitter like a phone.
Multiple alarm and protection functions (overvoltage, overcurrent, overheating, overpowering, over SWR, etc.).
Networked telemetry and remote control, which can be monitored by web page.
High reliability design, capable of working continuously for 24 hours.
