Frequency Down Converter 2.4G to 250Mhz DVB-T COFDM Digital HDTV RF Microwave Module Board
Frequency Down Converter 2.4G to 250Mhz DVB-T COFDM Digital HDTV RF Microwave Module Board
The frequency down-converter board converts the received 2.4GHz RF frequency signal into a 250MHz signal and then converts it into a digital signal through OFDM demodulation to the channel demodulation module.

FAQs
A RF frequency block downconverter (BDC) for wireless video transmitters is a device that can convert a high frequency range to a low frequency range.
Typically used on the wireless video transmitter side. Кылсярысь,
- From 5.8G to 2.4G down converter
- From 2.4G to 1.2G down converter
- From 1.2G to 600Mhz down converter
This is due to the fact that wireless transmission frequencies in many countries or regions are restricted by local laws and regulations.
It is not permitted to use in a specific frequency range.
To change the operating frequency of the transmitter and receiver, down-conversion or up-conversion is required. Make sure the transmission frequency is in accordance with local laws and regulations.
There is also the case where the professional receiving frequency is fixed, for example, between 300-800Mhz.
In order for the transmitter's frequency to be paired, тhe frequency of the 1.2G transmitter must be reduced.
All of this necessitates the use of a frequency downconverter for wireless video transmission.
Мед, our professional engineer replied, we can do it. And, before delivery, we will show you the test video.
Мед, our professional engineer confirms that we can re-design and modify some key components to do that. Sure, before delivery, we will show you the test video.
Thanks for your inquiry, I will check with our engineer.
Thanks for your inquiry. We can customize for you.
Please tell us the specification details of your transmitter and receiver modules.
Юан: We are interested in n.1 downconverter from 950-1500 Mhz to 350-850 Mhz and n.1 upconverter from 350-850 Mhz to 950-1500 МГц. Local oscillator 1800 МГц.
Мед, Here is our specification for your references.

Юан: If a signal of -25 dbm enter, what level has the coverterd output?
Ответ: 0 дБм
We can not make a frequency up convert from 1.0-2.5 GHz to 5.8 ГГц.
But we can produce the frequency up convert from 1.0-2.5 GHz to 4.3G~5.8 GHz. Every input frequency add 3.3G (3300МГц) to output frequency.
