Izici:
- Ukulahlekelwa Kokuguqulwa Okuphansi
- Ukuzihlukanisa Okuphezulu
1. Nikeza imininingwane yesigaba kanye ne-amplitude: Ngenxa yokufakwa kweziteshi ze-I ne-Q, i-IQ mixer inganikeza kokubili ulwazi lwesigaba nolwazi lwe-amplitude yesiginali. Lokhu kubalulekile kumasistimu amaningi okuxhumana okungenazintambo kanye nezinqubo zokuguquguquka kanye nokwehliswa kwabantu.
2. Qaphela ukucutshungulwa kwesignali ye-orthogonal: Iziteshi ze-I ne-Q ze-IQ mixer ziyakwazi ukucubungula amasignali we-orthogonal, okungukuthi, amasignali anomehluko wesigaba wama-degree angu-90. Lokhu kukwenza kube wusizo kakhulu kumasu amaningi okushintshashintsha nokudilizwa, njenge-orthogonal frequency division multiple access (OFDM) kanye ne-quadrature amplitude modulation (QAM).
3. Ukunciphisa ukuphazanyiswa kokulalela: I-IQ mixer iyakwazi ukuhlukanisa i-spectrum yesignali nokuphazamiseka ngenxa yokufakwa kwezindlela ezimbili zesigaba ezihambisanayo. Lokhu kuyenza ikwazi ukumelana nokuphazamiseka kokulalela.
4. Ububanzi obuguquguqukayo obuphezulu: Ngenxa yokusetshenziswa kwamashaneli amabili, abaxube be-IQ ngokuvamile banobubanzi obuguquguqukayo obuphezulu obungakwazi ukuhlangabezana nezinhlelo zokusebenza zokucubungula isignali ezidingekayo.
I-1.Izinhlelo zokuxhumana okungenantambo: I-IQ mixer isetshenziswa kakhulu ezinhlelweni zokuxhumana ezingenazintambo, okuhlanganisa nezinhlelo zokuxhumana zeselula, izinhlelo zokuxhumana ngesathelayithi kanye namanethiwekhi endawo angenazintambo. Isetshenziselwa ukudiliza isiginali eyamukelwe, ukulungisa isiginali ethunyelwe, futhi ibone ukwehla, ukuguquguquka kanye nokuguqulwa kwemvamisa kwesiginali.
2.Imodemu: Izixube ze-IQ ziyizingxenye eziyinhloko ezivame ukutholakala kumamodemu asetshenziselwa ukuhlanganisa amasignali e-baseband ebangeni le-RF ukuze adluliselwe, noma ukuhlanganisa amasiginali e-RF atholiwe abe yi-baseband ukuze akhishwe.
I-3.Ukudluliselwa kwedatha yesivinini esiphezulu: Ngenxa yokuthi abaxube be-IQ bangakwazi ukuphatha amasignali we-orthogonal, banezinhlelo zokusebenza ezibalulekile ekudluliseni idatha ngesivinini esikhulu. Isibonelo, ezinhlelweni zokuxhumana ze-optical kanye nokuxhumana kwedijithali okushesha kakhulu, ukuguquguquka kwe-QAM nokudilizwa kusetshenziswa izixube ze-IQ kungavumela ukudluliswa kwedatha ngesivinini esikhulu kanye namandla aphezulu.
I-4.Ukuhlaziywa kokuphazamiseka kwe-Carrier: Abaxube be-IQ bangasetshenziswa ekuhlaziyeni ukuphazamiseka kwenkampani yenethiwekhi, okungasiza ekunqumeni umthombo wokuphazamiseka nokuqeda ukuphazamiseka ngokulinganisa nokuhlaziya ulwazi lwesigaba nolwazi lwe-amplitude yesiginali.
QualwaveInc. ihlinzeka nge-IQ-mixers isebenza kusuka ku-1.75 kuya ku-26GHz.
