وحدة إرسال معدل تشفير الفيديو COFDM تدعم 1.4-2.4-3-3.6-4-4.9-5-6 جيجا هرتز
جدول المحتويات
1. Does your COFDM video encoder modulator transmitter module support 3.6G?
نعم فعلا, ملكنا 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?
لا, 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?
نعم فعلا, ملكنا 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 غيغاهرتز, 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 غيغاهرتز?
5GHz test also has output, the signal is slightly smaller
يمكن للأجهزة الجديدة لوحدة إرسال COFDM المنفصلة أن تدعم ما يزيد عن 3 جيجا هرتز, 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.
اذا كان ضروري, 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 (8عرض النطاق الترددي ميغاهرتز)
