COFDM Transceiver

O le a le COFDM Transceiver?

COFDM Transceiver o se pea o masini e mafai ona maua ma auina atu faʻamatalaga ma vitio. COFDM transmitter ma receiver o se tasi le auala fesoʻotaʻiga, e na'o le lagolagoina o felauaiga e tasi.

O le COFDM transceiver e aofia ai seti e lua o COFDM transmitters ma receivers, lea e felauai i itu faafeagai ina ia mafai e se masini e tasi ona maua ma auina atu faamatalaga, vitio, ma le leo i se isi masini fa'apipi'i. Ole COFDM Transceive ole a feso'ota'iga fe'avea'i ala lua.

O le COFDM transceiver o loʻo i ai fesoʻotaʻiga eternet IP RJ45, e pei o se uaea upega e le vaaia. E lagolagoina le fa'afeso'ota'i o se meapueata IP ma e lagolagoina fo'i le feso'ota'iina o komepiuta mamao e lua, e lagolagoina le taʻavale ping poloaiga i le Windows OS CMD, lea o le a tali mai i le taimi o felauaiga.

Auala e filifili ai se COFDM Transceiver?

Pe a filifilia se COFDM transceiver, atonu e manaʻomia ona e mafaufau i nisi o mea:

faisoʻoga

COFDM transmitters ma receivers e lafo i le tasi itu, e na'o le tasi lava le taimi e tatau ona iloiloina. COFDM transceiver o fa'asalalauga fa'alua, e lua la o alaleo e tatau ona iloiloina. E tatau ona tuueseese laina e lua i le tele e mafai ai e aloese ai mai le faalavelave. Ina ia faʻaumatia le faʻalavelave ma aloese mai le faʻalavelave, e mana'omia fo'i le fa'aopoopoina o se fa'amama pasi galu.

E mafai ona sau mai le va'aiga fa'apitoa fa'avevesi 170 i 860 MHz. Faataitaiga, filifili le 300Mhz mo le laina i luga ma le 600Mhz mo le laina lalo.

Ole filifiliga fa'apitoa e tatau fo'i ona mafaufau ile tulaga nofoia fa'alotoifale. Afai ei ai DVB-T poʻo DVB-T2 TV numera i totonu o le eria, e tatau foi ona aloese mai alaleo ua uma ona filifilia e le TV numera i le tele e mafai ai.

A mae'a ona filifili le taimi e fa'asalalau ai, e tatau fo'i ona fa'atumauina le fa'avevesi o le fa'avevela e fa'amae'a ai le felauaiga ma le taliaina.

Bandwidth

E le pei o le TV numera, lea ua 6, 7, ma le 8Mhz bandwidth, le COFDM transceiver's bandwidth e mafai ona faʻapitoa, pei ole 2MHZ ma le 4MHz.

mea faʻamau mana

O le faʻamalosi malosi o loʻo taʻua iinei o se masini e mafai ona faʻateleina le malosi o le COFDM faʻailoga faʻaalia mai le transmitter, lea e mafai ona faʻaleleia le lelei o faʻailoga ma faʻasalalauga.
E manaʻomia e le faʻamalosi malosi o le COFDM transmitter le faʻamautu laina laina ma le lelei. masani, filifili le malosi fa'aola talafeagai e fa'atatau i le mamao e te mana'omia e fa'asalalau. O lo'o i lalo le laulau o feso'ota'iga i le va o le felauaiga mamao ma le fa'amalo malosi mo lau fa'amatalaga.

alofaʻaga

O le maaleale e faasino i le mafaia e se transmitter vitiō uaealesi ona lafo faailoilo vaivai ma maua e le tagata e taliaina.

O le maaleale e masani ona fua ile decibels (dB) po o le decibel milliwatts (dBm) ma o lo'o fa'atusalia ai le tulaga maualalo ole mana fa'ailo e mafai ona iloa ma fa'agasolo e se transmitter.

O le maualuga o le lagona, sili atu le faʻatinoga ma le tele o fesoʻotaʻiga vitio uaealesi.

O oloa a le COFDM Transceiver

COFDM e masani ona lua COFDM faʻaogaina alalaupapa mai le 170Mhz i le 860Mhz. O alaleo filifilia e tatau ona va'ava'ai mamao e mafai ai ona 'alofia le fa'alavelave fa'atasi.
I le faʻaaogaina moni, e mana'omia le fa'aopoopoina o se fa'aliga malosi PA, faamama, ma antenna e fetaui ma taimi faigaluega.

Le afifi o le COFDM Transceiver

COFDM transceiver, ua faaigoaina foi Bidirectional COFDM Ethernet Radio, Alalaupapa Ethernet uaealesi lua.

E mafai ona e fa'avasegaina le 340Mhz ma le 554Mhz COFDM transceiver mo a'u?

ioe.

Why the two filters per transciever are used? One filter for RX and one PA for TX are enough?

1. Filters are added to avoid interfering with or being interfered with by other devices.
   Please test the transceiver first without connecting the filter.
2. The transmitter adds a filter because it has a power amplifier, It will emit a strong signal to avoid interfering with other equipment on the plane.
3. The receiver add filter allows the receiver to receive only the desired signal and avoid clutter, and that signal sensitivity is improved.
4. You need to connect the filter when the transmission distance is not far or the signal strength is very poor in the test.
5. If the transmitter does not add a filter, it may interfere with the flight control or the power battery. Some customers have encountered this phenomenon before, and the filter has solved the problem.
6. You take the sample now and suggest buying it together when you test it and need the filter, and it will take more time and freight to deliver it.

Can you customize the frequency 175Mhz and 320Mhz COFDM transceiver for me?
