 FMUSER FU-518A 5000W 5KW Analog VHF UHF TV Transmitter Rack Size

For Television Station Channel

 

 

Overview:
This 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 5000W.
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 LDMOS 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:
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 3000W 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 3000W power amplifier is installed in a 3U high 19-inch standard chassis, which is composed of four identical 750W 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 micro strip 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.

How far(long) the transmitter cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

EXAMPLE 5W FM Transmitter use in the city and hometown:

I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

Below are the approximate range of different power FM Transmitters. ( The range is diameter )

0.1W ~ 5W FM Transmitter :100M ~1KM

5W ~15W FM Ttransmitter : 1KM ~ 3KM

15W ~ 80W FM Transmitter : 3KM ~10KM

80W ~500W FM Transmitter : 10KM ~30KM

500W ~1000W FM Transmitter : 30KM ~ 50KM

1KW ~ 2KW FM Transmitter : 50KM ~100KM

2KW ~5KW FM Transmitter : 100KM ~150KM

5KW ~10KW FM Transmitter : 150KM ~200KM
