پرسش و پاسخ

س: Can you explain more about dropping down to 600 MHz to work with your cofdm transmitter and receiver module?
آ: Certainly. ما فرستنده platform supports a very wide operating frequency range of 175–3500 MHz, and in some configurations even 175–6000 MHz. با این حال, the internal tuner/demodulator chipset used in the receiver is designed to directly process signals only within approximately 175-860 مگاهرتز. This frequency range corresponds to the standard European DVB-T broadcast spectrum, where the receiver operates natively and most efficiently.

When the transmission frequency is above 860 MHz — for example in bands such as: 1.2 گیگاهرتز, 2.4 گیگاهرتز,5.8 گیگاهرتز. the receiver cannot directly demodulate the RF signal at those frequencies. In these cases, الف frequency downconverter is required.The downconverter shifts the higher RF frequency down into the receiver’s supported 175-860 مگاهرتز range before demodulation. Once converted, the receiver processes the signal normally using the DVB-T demodulator.

This is a standard approach used in many professional RF, پخش شود, and COFDM/DVB-T systems, allowing very wide frequency coverage while maintaining stable and reliable DVB-T reception performance.

1. Can the frequency range be customized?
بله. Both the input/output frequencies and LO can be customized based on your system requirements.
2. Does it support COFDM video transmission systems?
کاملا. The converter is designed for COFDM-based UAV and long-range video transmission.

3. Can it reduce interference from other 2.4 دستگاه های گیگاهرتز?
بله. Shifting the operating band to 3–3.5 GHz helps bypass crowded 2.4 GHz environments.

4. Is the module suitable for drone applications?
بله. It features compact size, مصرف برق کم, and stable RF performance.

5. Can you provide OEM/ODM customization?
