Shaandhada Sare ee LC: Xalka Sare ee RF ee loogu talagalay Band-ka 118-138MHz

Ku dadaal horumarinta joogtada ah ee isgaarsiinta wireless-ka iyo nidaamyada RF,Shaandheeyayaasha LC-ga ee heerka sare ahsi weyn ayaa loogu isticmaalaa codsiyada kala duwan ee VHF RF sababtoo ah qaab-dhismeedkooda isku dhafan, waxqabadkooda deggan, iyo jawaab celin dabacsan. Qaabka ALCF118M138M45N ee ay soo bandhigtay Apex Microwave waa tusaale caadi ah, oo loogu talagalay xarigga 118MHz ilaa 138MHz, iyadoo la tixgelinayo waxqabadka iyo isku halaynta labadaba.

Tanbadeecadwaa shaandho FM ah oo si madax-bannaan u samaysay Apex, kaas oo si wax ku ool ah u xakamayn kara nidaamyada baahinta raadiyaha FM ee 87-108MHz, isagoo si hufan u dhex maraya calaamadda bartilmaameedka ah ee 118-138MHz ee kooxda VHF, taas oo yarayn karta calaamadaha leexashada oo ka fogaan karta faragelinta nidaamka.

Theshaandhada sare ee LCr waxay leedahay lumis gelinta oo hooseeya≤1.0dB iyo khasaaro soo celin sare oo ah≥15dB, taasoo hubinaysa gudbinta calaamadaha oo deggan iyo yareynta faragelinta milicsiga. Waxay bixisaa awood xakameyn ah ilaa≥40dB oo ku jirta xarigga 87.5-108MHz, taasoo si wax ku ool ah u hagaajinaysa waxqabadka ka hortagga faragelinta nidaamka.

Waayo-aragnimo ahaanSoo saaraha shaandhada LC, Apex muddo dheer ayuu diiradda saarayayNaqshadeynta shaandhada LC RFwaxayna taageertaa baahiyaha habaynta macaamiisha ee kooxaha badan.badeecadwuxuu leeyahay awood qaadis awoodeed oo ah 50W, heerkul shaqayneed oo ah -40°C ilaa +85°C, waxay ku qalabaysan tahay is-dhexgalka nooca N, waxayna u hoggaansan tahay heerarka deegaanka ee RoHS.

Marka laga soo tago moodooyinka caadiga ah, waxaan sidoo kale taageernaa xalal kala duwan oo la habeeyey waxaana bixinnaa xalal la habeeyeynaqshadaha shaandhada saresi loo daboolo shuruudaha gaarka ah ee qaab-dhismeedka, is-dhexgalka iyo waxqabadka korontada.
