RF Babban Warewa BroadBand Masu Canza Mitar IQ Mixers
IQ Mixers wani nau'in mahaɗa ne na musamman wanda ya ƙunshi hanyoyin siginar lokaci guda biyu masu dacewa da ake kira "In-phase" (I) da "Quadrature" (Q).Sifofinsa sune kamar haka:
1. Samar da bayanan lokaci da girma: Saboda haɗar tashoshi na I da Q, mahaɗar IQ na iya samar da bayanan lokaci da girman siginar.Wannan yana da mahimmanci ga yawancin tsarin sadarwa mara igiyar waya da tsarin daidaitawa da haɓakawa.
2. Gane sarrafa siginar orthogonal: Tashoshin I da Q na mahaɗar IQ suna da ikon sarrafa sigina na orthogonal, wato, sigina tare da bambancin lokaci na digiri 90.Wannan yana sa ya zama da amfani sosai a cikin dabaru da yawa na daidaitawa da haɓakawa, irin su rarrabuwar mitar mita da yawa (OFDM) da quadrature amplitude modulation (QAM).
3. Rage tsangwama na sauraro: Mai haɗawa IQ yana iya raba sigina da bakan tsoma baki saboda haɗa hanyoyin haɗin lokaci guda biyu.Wannan yana sa ya fi ƙarfin magance tsangwama na saurara.
4. Babban kewayo mai ƙarfi: Saboda amfani da tashoshi biyu, masu haɗawa IQ yawanci suna da kewayon ƙarfi mai ƙarfi wanda zai iya saduwa da aikace-aikacen sarrafa sigina masu buƙata.
Ana amfani da mahaɗar IQ gabaɗaya a cikin abubuwa masu zuwa:
1.Wireless sadarwa tsarin: IQ mahautsini ana amfani da yadu a cikin mara waya tsarin sadarwa, ciki har da mobile sadarwa tsarin, tauraron dan adam tsarin sadarwa da kuma mara igiyar waya yankin cibiyoyin sadarwa.Ana amfani da shi don rage siginar da aka karɓa, daidaita siginar da aka aiko, da kuma gane ƙaddamarwa, daidaitawa da jujjuya siginar.
2.Modem: mahaɗar IQ sune mahimman abubuwan da aka saba samu a cikin modem waɗanda ake amfani da su don haɗa siginar tushe a cikin kewayon RF don watsawa, ko don haɗa siginar RF da aka karɓa cikin bandeji don lalatawa.
3.High-speed data watsa: Saboda IQ mixers iya rike da orthogonal sakonni, suna da muhimman aikace-aikace a high-gudun data watsa.Misali, a cikin tsarin sadarwa na gani da hanyoyin sadarwa na dijital mai sauri, QAM modulation da demodulation ta amfani da mahaɗar IQ na iya ba da damar watsa bayanai mai sauri da ƙarfi.
4.Carrier nazarin tsangwama: Ana iya amfani da mahaɗar IQ don nazarin tsangwama mai ɗaukar kaya, wanda zai iya taimakawa wajen ƙayyade tushen tsangwama da kuma kawar da tsangwama ta hanyar aunawa da kuma nazarin lokaci da girman bayanan siginar.
