সুচিপত্র
1. Does your COFDM video encoder modulator transmitter module support 3.6G?
হাঁ, আমাদের COFDM ট্রান্সমিটার মডুলেটর মডিউল supports 1.4-2.4-3-3.6-4-4.9-5-5.8-6Ghz
2. Does your COFDM demodulator decoder receiver module support 3.6G?
না, our COFDM demodulator decoder receiver module only supports 170-860Mhz. You need to use a frequency down converter module to work well with the 3.6G transmitter module.
3. Does your COFDM video relay repeat module support 3.6G?
হাঁ, আমাদের COFDM video relay repeat module supports a 3.6G transmitter and sends out, the receiver parts you need to use a frequency down converter block module to get the signal correctly from a 3.6Ghz transmitter.
The relay module transmission signal does not need a frequency down converter block module, and the reception also uses a normal COFDM video receiver module, which only supports up to 860MHz. If you need to receive higher frequency signals, পছন্দ 3.6 Ghz, you need to add a frequency down converter block module.
4. How about the test result of your COFDM video encoder modulator transmitter module at 5 গিগাহার্টজ?
5GHz test also has output, the signal is slightly smaller
আলাদা COFDM ট্রান্সমিটার মডিউলের নতুন হার্ডওয়্যার 3GHz এর উপরে সমর্থন করতে পারে, and its output signal is the same as that of the relay module, so you can first use the relay module with your own 3 Ghz~4 Ghz PA test. If the test is OK, then purchase a separate COFDM transmitter module.
যদি প্রয়োজন হয় তাহলে, you can also directly purchase samples of COFDM transmitter modules supporting 3 Ghz~4 Ghz frequency bands for testing
The following is the picture of our COFDM transmitter module Tx signal spectrum analyzer when we tested 3.5GHz and 4GHz (8MHz ব্যান্ডউইডথ)
5. What is the frequency range of the cofdm receiver?
Although the COFDM transmitter supports a frequency range of 70-3500Mhz, the receiver does not support such a wide range and currently only supports 161-860Mhz. If you still want to use an operating frequency beyond this range, you need to use a frequency downconverter.
