Description:
- 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 10KW transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.
Features:
- The whole machine is single-channel, image with audio together.
- The management and monitoring are intelligent and on network, it has the external PC interface.
- It has the technical data detection, monitoring systems and full-featured computer control software with auto-diagnostic function. All technical parameters can be read through the LCD display panel.
- Comprehensive protection measures can reduce the damage of equipments. This machine has protection about no video; VSWR is too large, overheating, over-stimulus, missing phase protection and lightning protection. The switch has protection about overvoltage, over current, under voltage, over temperature, short circuit and lightning protection.
- All power supplies are switching power supplies; high efficiency, excellent regulator range, strong adaptable from the change of the external voltage.
- It adopts modular design concept.
- Hot-pluggable design: power amplifier and switching power are supporting the Hot-plug, it’s easy to debug and maintenance; improve the reliability.
- The fan is built-in the chassis, the transmitter has a compact structure and a beautiful shape.

Common Problems:
In order to be more comprehensive understanding of the knowledge about our products,we collect all the analyses of problems for every order,hope it will help you.
Q1. What these equipments used for?
A1. We are original manufacturer in FM Radio & TV Broadcasting equipments; they are professional used for FM Radio & TV Broadcasting Station (Transmitting equipment.)
Q2. What equipment & solution your company can provide?
A2. We can do complete solution for FM Radio Station System. It includes:
Studio--Link--Transmitter--Cables--Antenna.
We also can provide complete Transmitting part of TV Station. It includes:
Link—Transmitter—Cables—Antenna.
Q3. How large areas can One Station cover?
A3. One FM or TV Station can cover one city or one town.
The Maximum cover ranges of one station can not over 100KM Radius because the Earth is Curve.
You can use Multiple Stations & Different Frequency to cover larger area.
Q4. How do I choose suitable equipments for my station?
A4. The most import factors are Power and Frequency.
We need to know the Power and Frequency you need exactly.
How long the distances do you want to cover in Radius?
How height your Antenna can be installed?
Q5. How to calculate Broadcasting equipment Cover Range?
A5. The Cover Range depends on 4 factors:
1. Power from Transmitter; 2. Height of Antenna; 3. Gain from Antenna; 4. Around Environment.
Then we can know the cover range of your station.
Q6. Is the Frequency Adjustable?
A6. FM Radio Band Frequency is 87~108MHz, TV Band Frequency includes UHF/VHF band.
For FM Radio Transmitter; Power Below 2KW is all adjustable. Above 2KW would be narrow.
For TV Transmitter; all Frequency Band is very Narrow, only can contain around 3 Channels; so it’s not adjustable.
Q7. Is your Analog TV Transmitter can be upgraded to Digital?
A7. Yes, we can. But the Frequency Band should be the same.
The only difference between Analog & Digital TV Transmitter is its TV Modulator.
After upgrade to Digital, the Power from TV Transmitter reduced 5 times.
For example: 1KW analog TV Transmitter can be upgraded to 200W Digital TV Transmitter.
Q8. How to do installation of these equipments?
A8. For small power station, the equipments are very easy for installation.
For large power station, we can send our engineer to your country to help you do the installation, but you should pay the cost.
We also can do training for your engineer here in our company.
Q9. How to operate these broadcasting equipments?
A9. We provide All-English user manual; All-English operation software in our equipment.
We also can do training for your engineer here in our company.
Q10. What about after sales?
A10. The warranty time is one year after goods leaving factory.
We can provide technical support from internet or in our company.
We can send spare parts to you directly when the equipment damaged.
