ievads
The module is a relay module, not a completed item. Customers need to add a power amplifier, filters, and receiving and transmitting antennas for it to work effectively. These need to be customized according to the two working frequencies selected by the customer.
To prevent interference, the drone employs a single frequency (piem. 400Mhz) for communication with the relay, and a different frequency (piem. 700Mhz) for communication between the relay module with the receiver. The separation between the two should be as large as possible.
iezīme

- Lowest latency 200-300 milisekundes
- Widely frequency range 200Mhz-3000Mhz
- atbalsts Frekvenču joslas
- joslas platums 1Mhz-8Mhz fakultatīvs
- Video signal repeater for long-distance

Monitoring and control
This COFDM relay repeater module can complete setup with our Parameter Configure Tool or STM32+LoRA (or other devices) via control uart. With our parameter configure too, the following parameters can be set:
– RX Received frequency (F1) and bandwidth (B1)
– TX Transmitted frequency (F2), joslas platums (B2), FEC, aizsargs intervāls, constellation, and transmission power

FAQ
- Our COFDM Video Transceiver relay repeater supports 170-860Mhz. The COFDM transmitter also supports 2300Mhz, but the COFDM receiver only supports up to 860Mhz, 861-930Mhz receiver our COFDM-221 supports, over 930Mhz-2300Mhz needs to plus the frequency downconverter block to support.
- Our COFDM relay repeater module supports all the COFDM transmitters and receivers, the transmission distance depends on your external power amplifier and filter support.
