ماژول فرستنده مدولاتور رمزگذار ویدئو COFDM از 1.4-2.4-3-3.6-4-4.9-5-6Ghz پشتیبانی می کند.

2. Does your COFDM demodulator decoder receiver module support 3.6G?

خیر, 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?

بله, ما 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, پسندیدن 3.6 گیگاهرتز, 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 گیگاهرتز?

5GHz test also has output, the signal is slightly smaller

سخت افزار جدید ماژول فرستنده COFDM مجزا می تواند فرکانس بالای 3 گیگاهرتز را پشتیبانی کند, 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.

در صورت لزوم, 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 (8پهنای باند مگاهرتز)

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.
