RF TX module COFDM mai watsawa 70Mhz 80Mhz 150Mhz 160Mhz
Teburin Abubuwan Ciki
Shin tsarin RF TX ɗinku na COFDM yana goyan bayan aiki har zuwa 150 MHz ko ƙasa?
Yanzu mun lura yana goyan bayan 200 MHz ~ 2300MHz. Bisa ga bayanin TX module datasheet, ba a ba da shawarar yin aiki a ƙasa da 200MHz. Bari mu ɗauki allo mu gwada shi daga baya don ganin ko yana aiki.
iVcan: Injiniyan mu ya gwada RF TX module COFDM mai watsa pcba. Matsakaicin mafi ƙanƙanta ko mafi ƙanƙanta na iya kaiwa 70Mhz, amma mafi ƙarancin kewayon mai karɓar mu na 160Mhz kuma har zuwa 860Mhz.
Idan kun saita tsarin TX akan 70Mhz, sannan ana buƙatar allon canzawa.
Ƙananan mitar, mafi girman ikon watsawa.
Ƙarfin wutar lantarki mai ƙasa da PA 200 megabytes zai fi girma.
Client: Don buƙatar na yanzu, 160Mhz yana da kyau, don haka ba tare da allo mai canzawa ba.
Muna amfani da ƙaramin ƙarfi daga tsarin TX kuma bayan mun yi amfani da namu PA, don haka ba tambayarka bane. Muna buƙatar fitarwa na Tx na kusan -10dBm.
iVcan: A 160 MHz, Matsakaicin fitarwa na tsarin watsawa yana tsakanin -3dBm da -5dBm. I mana, Hakanan za'a iya saita shi zuwa -10dBm ta hanyar umarnin AT ko allon ma'auni.
Client: -5dBm yana da kyau, Da fatan za a gwada a -5 dBm fitarwa na Tx module.
The waveform lokacin da fitarwa-5DBM aka fitarwa a lokacin gwaji na TX module
Shin Modul ɗin RF TX ɗinku yana goyan bayan 3.5G?
COFDM Video encoder modulator transmitter module 3.5G da sakamakon gwajin 4G.
Kuna iya aiko mana da tsarin ku na COFDM TX RX tare da casing karfe da amplifier a ciki?
a, za mu iya ba ku cikakken saitin na'urorin COFDM TX RX tare da casing karfe da amplifier (1-wata PA, 2.5-wata PA, ko 10-watt PA na zaɓi)r, da eriya mai watsa cofdm da eriya mai karɓa.
