Izindaba - Isihlanganisi se-Cavity 80-2700MHz: ukuhlukaniswa okuphezulu, ukulahlekelwa okuphansi kwe-multi-band RF ehlanganisa isisombululo

Iisihlanganisi se-cavityeyethulwe yi-Apex Microwave ihlanganisa amabhendi amabili okuxhumana ajwayelekile angu-80-520MHz kanye no-694-2700MHz, futhi yakhelwe izinhlelo zokusebenza zokuhlanganiswa kwesiginali enamabhendi amaningi njengokuxhumana okungenantambo, amasistimu eziteshi eziyisisekelo, kanye nezinhlelo ze-antenna ezisabalalisiwe ze-DAS. Ngokuhlukaniswa okuphezulu, ukulahleka kokufakwa okuphansi nokusebenza okuhle kakhulu kwe-intermodulation, lesi sihlanganisi se-cavity sesiphenduke inketho ekahle yokuhlanganiswa kwesistimu ye-RF esebenza kahle kakhulu.

Iisihlanganisi se-cavityisebenza kahle kuwo womabili amabhendi e-P1 (80-520MHz) kanye ne-P2 (694-2700MHz), ngokulahleka kokufaka kwe-P1 okuphansi njenge≤0.4dB kanye nokulahlekelwa kokufakwa kwe-P2≤0.6dB, kwehlisa ngempumelelo ukulahlekelwa kwamandla esistimu. Ukusebenza kwe-PIM kufinyelela -155dBc@900MHz kanye -161dBc@1900MHz, kuqinisekisa ikhwalithi yesiginali ezindaweni ezinezinkampani eziningi. Ukulahlekelwa yimbuyiselo≥16.5dB, futhi ukuhlukaniswa kuyinto≥50dB kubhendi yefrikhwensi eyinhloko, ethuthukisa kakhulu ikhono lokulwa nokuphazamiseka kohlelo.

Iisihlanganisi se-cavityisekela isilinganiso samandla aphezulu angu-120W namandla aphezulu afika ku-3000W, afanele izimo zokuxhumana zamandla aphezulu. Iumkhiqizoisixhumi esibonakalayo sisebenzisa isixhumi esijwayelekile esingu-4.3-10 Sesifazane, ubukhulu bubonke bungu-187.2×130.4×31.8mm, isisindo≤I-1.4kg, igobolondo lenziwe ngengxube ye-aluminium oxidized oxidized, indawo engaphezulu ingakhethwa ku-Grey, i-Akzo Nobel RA7035, i-Powder spraying, enezinga lokuvikela le-IP67, elifanele izindawo ezingaphandle nezimboni.

Ngaphezu kwalokho, i-isihlanganisi se-cavityuphumelele isitifiketi esijwayelekile sokuvikelwa kwemvelo se-RoHS 6/6, izinga lokushisa elisebenzayo lingu-35°C kuya +65°C, futhi isekela ukucutshungulwa kokubukeka okwenziwe ngokwezifiso kwamakhasimende kanye nokucushwa kwesixhumi esibonakalayo, ukuhlangabezana nezimo nezidingo zamaphrojekthi ahlukene.

Njengesisetshenziswa esizimele sodwa, esizinzile kakhulu se-RF, isihlanganisi se-Apex Microwave sika-cavity sisetshenziswa kabanzi eziteshini eziyisisekelo ze-5G, ezokuxhumana zikaloliwe, ezokuxhumana eziphuthumayo, izinhlelo ze-radar, ezokuxhumana ezizimele nezinye izinkambu. Kuyisixazululo esithandwayo samakhasimende aphishekela ukusebenza kwesistimu okuhle kakhulu.
