COFDM Relay Repeater

I-COFDM Relay Repeater module ye-drone UAV isidlulisi sevidiyo esingenantambo nomamukeli Vcan1870

Isingeniso

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 (isb. 400MHz) for communication with the relay, and a different frequency (isb. 700MHz) for communication between the relay module with the receiver. The separation between the two should be as large as possible.

Isici

1. Wireless Video COFDM Video Data demodulation and re-modulation
2. Ukudluliswa kwesignali okuzinzile ku-NLOS nokuhamba ngesivinini esiphezulu (less than 600km/hour)
3. Imvamisa yokusebenza elungisekayo, komkhawulokudonsa, amandla okudlulisa, njll (Special Parameter Configure Tool or UART STM32 LoRA )
4. Lowest latency 200-300 millisecond
5. Widely frequency range 200Mhz-3000Mhz
6. Amaprosesa asekelwe I-HDMI noma i-SDI noma i-CVBS
7. Komkhawulokudonsa 1Mhz-8Mhz ozikhethela
8. Video signal repeater for long-distance

Isingeniso

Ukucaciswa:

IO

RF okokufaka	Two SMA females (to receive the signal)
Ukukhishwa kwe-RF	I-SconB noma i-SconC (to send out the signal again)
control UART	4I-PIN PH1.25mm Isixhumi
Okokufaka Kwevidiyo Ehlanganisiwe	2I-PIN PH2.54mm phenix Isixhumi
Ikhadi le-TF	Ukuze uthole isibuyekezo se-firmware
I-power led	red LED, constant light when the device is normally powered
Isixhumanisi siholwa	green led, blinks on transmitting the received data

I-RF Yamukelwe

imvamisa Amabhendi	160MHz ~ 860MHz (need an extra down converter block for 860-2300Mhz)
Ukushuna usayizi wesinyathelo	1kHz
ukuzwela	-97±1dBm(BW=8MHz, QPSK, I-CR=2/3, I-GI=1/16) esiteshini esisodwa bese wengeza i-3dBm yamashaneli amabili

I-RF idluliselwe

imvamisa Amabhendi	200MHz~2300MHz(other bands can be supported with special manufacturing)
Ukushuna usayizi wesinyathelo	1kHz
Power out	Kuyalungiseka, esiphezulu -5dBm(ngaphansi kwemvamisa)

Ukuqapha nokulawula
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) kanye nomkhawulokudonsa (B1)
– TX Transmitted frequency (F2), komkhawulokudonsa (B2), FEC, unogada isikhawu, constellation, and transmission power

Izinga lokushisa ububanzi
I-HDMI noma i-SDI noma i-CVBS: 0° kuya +70°C Ambient
Storage: I-HDMI noma i-SDI noma i-CVBS

Izidingo zamandla
kungabandakanyi izixhumi eziphuma ebhodini: 7~ 24VDC
Power ukusetshenziswa: <250mA@12V

Izici Physical
Ubukhulu: 73x51x15mm
Isisindo esikhulu: 32.4 amagremu

 

Imiyalo ye-UART AT

The AT commands mainly used in the COFDM Wireless Relay Repeater are I-ATDR, I-ATSD, I-ATGD, I-ATSR, I-ATGR, and ATGB. For the introduction of specific commands, see the document.

Imibuzo Evame Ukubuzwa

1. What frequency does it support? Does it work well for my existing cofdm video transmitter and receiver?

1. 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.
2. Our COFDM relay repeater module supports all the COFDM transmitters and receivers, the transmission distance depends on your external power amplifier and filter support.

2. Ingabe le mojula isekela ngaphezu kwe-1.4G? isibonelo 2.4G, 3G, noma 3.6G?

1. Yebo, ukweseka.

   I-COFDM Video encoder transmitter module 3.5G kanye nomphumela wokuhlola we-4G.
