    Ama-Microwave Mixers awuhlobo olukhethekile lomxube oluqukethe izindlela ezimbili zesignali zesigaba ezihambisanayo ezibizwa ngokuthi "In-phase" (I) kanye ne-"Quadrature" (Q). Izici zawo zimi kanje:

    1. Nikeza ulwazi lwesigaba kanye nobungako: Ngenxa yokufakwa kweziteshi ze-I kanye ne-Q, i-radio frequency IQ mixer inganikeza ulwazi lwesigaba kanye nobungako besignali. Lokhu kubalulekile ezinhlelweni eziningi zokuxhumana ezingenantambo kanye nezinqubo zokuguqula kanye nokususa umsindo.
    2. Qaphela ukucutshungulwa kwesignali ye-orthogonal: Iziteshi ze-I ne-Q zabaxubi be-RF ziyakwazi ukucubungula izibonakaliso ze-orthogonal, okungukuthi, izibonakaliso ezinomehluko wesigaba sama-degree angu-90. Lokhu kwenza i-radio frequency mixer ibe usizo kakhulu kumasu amaningi okuguqula kanye nokususa, njenge-orthogonal frequency division multiple access (OFDM) kanye ne-quadrature amplitude modulation (QAM).
    3. Ukuphazamiseka kokulalela okuncishisiwe: I-IQ mixer iyakwazi ukuhlukanisa isignali kanye ne-interference spectrum ngenxa yokufakwa kwezindlela ezimbili zesigaba ezihambisanayo. Lokhu kuyenza ibe namandla okulwa nokuphazamiseka kokulalela.
    4. Ububanzi obuphezulu obuguquguqukayo: Ngenxa yokusetshenziswa kweziteshi ezimbili, abaxubi be-IQ ngokuvamile banebanga eliphezulu eliguquguqukayo elingahlangabezana nezinhlelo zokusebenza zokucubungula isignali ezidingakalayo.

    I-IQ mixer ivame ukusetshenziswa kulezi zici ezilandelayo:

    1. Izinhlelo zokuxhumana ezingenantambo: I-Millimeter wave mixer isetshenziswa kabanzi ezinhlelweni zokuxhumana ezingenantambo, okuhlanganisa izinhlelo zokuxhumana zeselula, izinhlelo zokuxhumana ngesathelayithi kanye namanethiwekhi endawo angenantambo. Isetshenziselwa ukwehlisa isivinini sesignali etholakele, ukulinganisela isignali ethunyelwe, kanye nokufeza ukuguqulwa kwesivinini, ukuguqulwa kwesivinini kanye nokuguqulwa kwesivinini sesignali.
    2. Ama-modem: IQ mixers ayizingxenye ezibalulekile ezivame ukutholakala kuma-modem asetshenziselwa ukuxuba amasignali e-baseband kububanzi be-RF ukuze adluliselwe, noma ukuxuba amasignali e-RF atholiwe ku-baseband ukuze kukhishwe amandla.
    3. Ukudluliswa kwedatha ngesivinini esikhulu: Ngenxa yokuthi abaxubi be-IQ bangakwazi ukuphatha izimpawu ezihambisanayo, banezinhlelo zokusebenza ezibalulekile ekudlulisweni kwedatha ngesivinini esikhulu. Isibonelo, ezinhlelweni zokuxhumana ze-optical kanye nokuxhumana kwedijithali ngesivinini esikhulu, ukuguqulwa kwe-QAM kanye nokususwa kwe-demodulation kusetshenziswa abaxubi be-IQ kungenza kube lula ukudluliswa kwedatha ngesivinini esikhulu kanye nomthamo ophezulu.
    4. Ukuhlaziywa kokuphazamiseka kwenkampani: Ama-IQ mixers angasetshenziswa ekuhlaziyweni kokuphazamiseka kwenkampani, okungasiza ekunqumeni umthombo wokuphazamiseka nokuqeda ukuphazamiseka ngokulinganisa nokuhlaziya ulwazi lwesigaba kanye nobubanzi besignali.

    I-QualwaveI-Inc. inikeza ama-IQ-mixer asebenza kusukela ku-1.75 kuya ku-26GHz.
