I-80dB High Rejection Bandpass Cavity Filter Esebenza kusukela ku-864-872MHz
Isihlungi se-RF Band pass JX-CF1-864M872M-80S yakhelwe ukudayiswa yi-Jingxin, esebenza kusukela ku-864-872MHz ngebhendi yokudlula engu-8MHz. Inokwenqatshwa okuphezulu okungaphezu kuka-80dB @ 721-735MHz, VSWR ngaphansi kuka-1.2, efakwe ngokulahlekelwa kokufakwa ngaphansi kuka-1.0dB, i-ripple ngaphansi kuka-0.2dB, amandla okusebenza ngaphansi kuka-30W. Njengoba inevolumu encane elinganiswa kuphela 54mm x 54mm x 38mm ngezixhumi ze-SMA, ipendwe ngombala omhlophe impilo ende, eminye imibala yokudweba iyabonakala futhi.
Lesi sihlungi se-cavity singasebenzela isixazululo sokuphepha komphakathi. Njengenkampani yokuhlunga ye-RF, i-Jingxin ingakusekela ngensizakalo yokuklama yangokwezifiso, isihlungi se-band pass cavity siyatholakala ngokufunwa nguwe. .Ngokuzibophezela, zonke izingxenye ze-RF ezingenzi lutho ezivela ku-Jingxin zinewaranti yeminyaka emi-3.

Izingxenye ze-RF Passive zangokwezifiso
Izinyathelo Ezi-3 Kuphela Zokuxazulula Inkinga Yakho Yengxenye Ye-RF Passive
1.Ukuchaza ipharamitha nguwe.
2.Ukunikeza isiphakamiso sokuqinisekiswa nguJingxin.
3.Ukukhiqiza i-prototype ukuze ihlolwe ngu-Jingxin.
