Maswali Yanayoulizwa Mara kwa Mara
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. Kwa mfano,
- 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, kwa mfano, between 300-800Mhz.
In order for the transmitter's frequency to be paired, the frequency of the 1.2G transmitter must be reduced.
All of this necessitates the use of a frequency downconverter for wireless video transmission.
Ndiyo, our professional engineer replied, we can do it. And, before delivery, we will show you the test video.
