3KW Analog TV Transmitter Modular Design

Product introduction：This 3KW Analog TV Transmitter is a high-standard, broadcast-grade cabinet-type all-solid-state analog TV transmitter with a modular structure, which is very convenient for maintenance.

Overview:

This 3KW Analog TV Transmitter is a high-standard, broadcast-grade cabinet-type all-solid-state analog TV transmitter with a modular structure, which is very convenient for maintenance. 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 RF amplification, the output power can be 3000W.

The 3000W 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 LDMOS high-power field effect transistors, Analog/Digital Compatible, stable and reliable.

The whole 3000W TV Transmitter adopts 19 “standard stainless steel case, suitable for all levels of TV stations.

Features:

● Analog TV exciter with new digital technology, superior performance, high reliability and good consistency.

● The main and backup exciter configurations can be used to reduce the stop rate (spare exciter and automatic switch are optional).

● With no video, over standing wave ratio, over power, over voltage, over current, over temperature and other protection functions to reduce equipment damage.

● Power control adopts closed-loop automatic gain control to ensure stable output power without drift.

● The power amplifier unit is composed of two independent 2000W power amplifiers. Each power amplifier uses three original imported high-quality long-life and large-volume axial fans in parallel, with large redundant air volume and good heat dissipation effect, so that the transmitter is in a low temperature state, which can extend the life of the transmitter.

● The 2000W power amplifier is installed in a 3U high 19-inch standard chassis, which is composed of four identical 500W power amplifier modules for low loss, high isolation and in-phase synthesis. The power redundancy design has a large margin and high reliability.

● The power amplifier module uses the latest high efficiency and high standing wave ratio LDMOS tube, adopts microstrip impedance conversion technology, simple and efficient, good consistency, easy maintenance and replacement.

● 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; and flexible N + 1 heat Plug-in configuration scheme, parallel current sharing centralized power supply. It can also be redundantly configured according to customer requirements.

● With intelligent network management and monitoring, with RS232 and TCP / IP communication interface.
