Isihlanganisi seTETRA esiKhulu esiHlanganisiweyo se-380-470MHz
Isixhobo sokudibanisa iTETRA sisixhobo seRF esisetyenziswa kwiinkqubo zeTETRA (Terrestrial Trunked Radio) ukudibanisa iitshaneli ezininzi zokudlulisa okanye zokwamkela kwi-antenna enye okanye inani elincinci lee-antenna ports. Umsebenzi ⭐Idibanisa ii-transmitters ezininzi ze-TETRA base station zibe yi-antenna enye...Funda ngokugqithisileyo -
Abahlalutyi be-Intermodulation abangasebenziyo
Ngenxa yokwanda kweemfuno zeenkqubo zonxibelelwano eziphathwayo, iPassive Intermodulation (PIM) ibe yingxaki ebalulekileyo. Imiqondiso enamandla aphezulu kwiitshaneli zothumelo ezabelwanayo zinokubangela ukuba izinto eziziilayini ezinje ngee-duplexers, izihluzi, ii-antenna, kunye nezihlanganisi zibonise iimpawu ezingezizo eziziilayini...Funda ngokugqithisileyo -
Indima ye-RF front-end kwiinkqubo zonxibelelwano
Kwiinkqubo zonxibelelwano zanamhlanje, i-Radio Frequency (RF) front-end idlala indima ebalulekileyo ekwenzeni unxibelelwano olungenazingcingo lube nempumelelo. Ibekwe phakathi kwe-antenna kunye ne-digital baseband, i-RF front-end inoxanduva lokucubungula imiqondiso engenayo nephumayo, nto leyo eyenza ukuba ibe yi-com...Funda ngokugqithisileyo -
Izisombululo eziphambili zeenkqubo zonxibelelwano olungxamisekileyo zokhuseleko loluntu
Kwicandelo lokhuseleko loluntu, iinkqubo zonxibelelwano olungxamisekileyo zibalulekile ekugcineni unxibelelwano ngexesha leengxaki. Ezi nkqubo zidibanisa ubuchwepheshe obahlukeneyo obufana namaqonga angxamisekileyo, iinkqubo zonxibelelwano lwesathelayithi, iinkqubo ze-shortwave kunye ne-ultrashortwave, kunye nokubeka esweni ukuva okukude ...Funda ngokugqithisileyo
