COFDM video encoder modulator transmitter module supports 1.4-2.4-3-3.6-4-4.9-5-6Ghz
สารบัญ
1. Does your COFDM video encoder modulator transmitter module support 3.6G?
ใช่, ของเรา COFDM transmitter modulator module 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?
ไม่, 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?
ใช่, ของเรา 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, like 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 GHz?
5GHz test also has output, the signal is slightly smaller
The new hardware of the separate COFDM transmitter module can support above 3GHz, 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.
ในกรณีที่จำเป็น, 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 (8แบนด์วิดธ์ MHz)
