Abaxubi be-IQ RF Microwave Millimeter Wave High Frequency Radio
IMixube yeMicrowave luhlobo olukhethekileyo lomxube oqulethe iindlela ezimbini zomqondiso wesigaba esongezelelweyo esibizwa ngokuba yi "In-phase" (I) kunye ne "Quadrature" (Q). Iimpawu zayo zezi zilandelayo:
1. Ukubonelela ngesigaba kunye nolwazi lwe-amplitude: Ngenxa yokufakwa kweziteshi ze-I kunye ne-Q, i-radio frequency IQ mixer inokubonelela zombini isigaba kunye nolwazi lwe-amplitude yesignali. Oku kubalulekile kwiinkqubo ezininzi zonxibelelwano ezingenazingcingo kunye neenkqubo zokumodareyitha kunye nokunciphisa.
2. Qonda ukusetyenzwa komqondiso we-orthogonal: Iitshaneli ze-I kunye ne-Q ze-RF mixers ziyakwazi ukucubungula iimpawu ze-orthogonal, oko kukuthi, iimpawu ezinomahluko wesigaba se-90 degrees. Oku kwenza umxube werediyo werediyo ube luncedo kakhulu kwiindlela ezininzi zokumodareyitha kunye neendlela zokwehlisa, ezinje nge-orthogonal frequency division yofikelelo oluninzi (OFDM) kunye nequadrature amplitude modulation (QAM).
3. Ukunciphisa ukuphazamiseka kokumamela: Umxube we-IQ uyakwazi ukwahlula umqondiso kunye nokuphazamiseka kwe-spectrum ngenxa yokufakwa kweendlela ezimbini zesigaba esongezelelweyo. Oku kuyenza ikwazi ukumelana nophazamiseko lokuva.
4. Uluhlu oluphezulu oluguquguqukayo: Ngenxa yokusetyenziswa kwamajelo amabini, abaxube be-IQ ngokuqhelekileyo banoluhlu oluguquguqukayo olunokuthi luhlangabezane nezicelo ezifunekayo zokucwangcisa umqondiso.
Umxubi we-IQ usetyenziswa ngokubanzi kule miba ilandelayo:
I-1.Iinkqubo zonxibelelwano ezingenazintambo: I-Millimeter wave mixer isetyenziswa ngokubanzi kwiinkqubo zonxibelelwano ezingenazintambo, kubandakanywa iinkqubo zonxibelelwano zeselula, iinkqubo zonxibelelwano zesatellite kunye neenethiwekhi zendawo ezingenazintambo. Isetyenziselwa ukuthoba umqondiso ofunyenweyo, ukulungelelanisa umqondiso othunyelweyo, kunye nokuqonda ukuthotywa, ukuguqulwa kunye nokuguqulwa kwamaza omqondiso.
2.IModem:Imixube ye-IQ ngamalungu aphambili axhaphake afumaneka kwiimodem ezisetyenziselwa ukuxuba iimpawu zebhendi kuluhlu lweRF ukuze lusasazeke, okanye ukuxuba iisignali zeRF ezifunyenweyo kwibaseband ukuze zithotywe.
I-3.I-Speed-Speed data transmission: Ngenxa yokuba abaxube be-IQ banokusingatha iimpawu ze-orthogonal, banezicelo ezibalulekileyo kwi-high-speed data transmission. Ngokomzekelo, kwiinkqubo zonxibelelwano lwe-optical kunye nonxibelelwano lwedijithali olukhawulezayo, ukumodareyitha kwe-QAM kunye nokuchithwa kwe-demodulation usebenzisa i-IQ mixers inokuvumela ukuhanjiswa kwedatha ye-speed kunye ne-high-capacity data.
Uhlalutyo lwe-4.Carrier interference analysis: Abaxube be-IQ bangasetyenziselwa uhlalutyo lwe-carrier interference, olunokukunceda ukufumanisa umthombo wokuphazamiseka kunye nokuphelisa ukuphazamiseka ngokulinganisa kunye nokuhlalutya ulwazi lwesigaba kunye ne-amplitude yesiginali.
QualwaveI-Inc. inikezela nge-IQ-mixers isebenza ukusuka kwi-1.75 ukuya kwi-26GHz.
