COFDM Relay Repeater

COFDM Relay Repeater module rau drone UAV wireless video transmitter thiab receiver Vcan1870

Introduction

Lub module yog ib tug relay module, tsis yog ib yam khoom tiav. Cov neeg siv khoom yuav tsum tau ntxiv lub hwj chim amplifier, lim, thiab tau txais thiab xa cov kav hlau txais xov kom nws ua haujlwm tau zoo. Cov no yuav tsum tau kho raws li ob qho kev ua haujlwm zaus xaiv los ntawm cov neeg siv khoom.

Txhawm rau tiv thaiv kev cuam tshuam, lub drone siv ib zaus (e.g. 400Mhz) rau kev sib txuas lus nrog lub relay, thiab lwm zaus (e.g. 700Mhz) rau kev sib txuas lus ntawm lub relay module nrog lub receiver. Kev sib cais ntawm ob qho tib si yuav tsum loj npaum li qhov ua tau.

1. Wireless Video COFDM Video Data demodulation thiab re-modulation
2. Kev ruaj ntseg teeb liab hloov hauv NLOS thiab kev txav ceev (tsawg dua 600 km / teev)
3. Adjustable ua hauj lwm zaus, bandwidth, fais fab kis, thiab lwm yam (Tshwj xeeb Parameter Configure Tool los yog UART STM32 LoRA )
4. Tsawg tshaj latency 200-300 milliseconds
5. Dav ntau zaus 200Mhz-3000Mhz
6. Kev them nyiaj yug Tuning Kauj ruam loj
7. bandwidth 1Mhz-8Mhz yeem
8. Video teeb liab repeater rau kev ncua deb

FAQs

1. Dab tsi zaus nws txhawb? Nws puas ua haujlwm zoo rau kuv qhov uas twb muaj lawm cofdm video transmitter thiab receiver?

1. Peb COFDM Video Transceiver relay repeater txhawb 170-860Mhz. Lub COFDM transmitter kuj txhawb 2300Mhz, tab sis COFDM txais tsuas yog txhawb nqa txog 860Mhz, 861-930Mhz txais peb COFDM-221 txhawb nqa, tshaj 930Mhz-2300Mhz xav tau ntxiv rau qhov zaus downconverter thaiv los txhawb.
2. Peb COFDM relay repeater module txhawb txhua COFDM transmitters thiab receivers, qhov kis tau tus mob nyob ntawm koj sab nraud lub zog amplifier thiab lim kev txhawb nqa.

2. Puas yog qhov module no txhawb tshaj 1.4G? eg 2.4 g, 3G, los yog 3.6g?

1. Yog, kev pab txhawb nqa.

   COFDM Video encoder modulator transmitter module 3.5G thiab 4G xeem tau.
