RF Isolation BroadBand na Frequency Converters IQ Ivanga
IQ ivanga ni ubwoko bwihariye bwo kuvanga burimo inzira ebyiri zuzuzanya zerekana ibimenyetso byiswe "In-phase" (I) na "Quadrature" (Q).Ibiranga ni ibi bikurikira:
1. Tanga icyiciro na amplitude amakuru: Kuberako ushizemo imiyoboro ya I na Q, mixer ya IQ irashobora gutanga ibyiciro byombi na amplitude yamakuru yikimenyetso.Ibi nibyingenzi kuri sisitemu nyinshi zitumanaho zidafite insinga hamwe na modulation na demodulation.
2. Menya uburyo bwo gutangiza ibimenyetso bya orthogonal: I na Q imiyoboro ya IQ ivanga irashobora gutunganya ibimenyetso bya orthogonal, ni ukuvuga ibimenyetso bifite itandukaniro ryicyiciro cya dogere 90.Ibi bituma bigira akamaro cyane muburyo bwinshi bwo guhindura no kugabanya demodulation, nka orthogonal frequency frequency igabana inshuro nyinshi (OFDM) hamwe na quadrature amplitude modulation (QAM).
3. Kugabanya gutegera kwumva: IQ ivanga irashobora gutandukanya ibimenyetso nibitandukanya bitewe no gushyiramo inzira ebyiri zuzuzanya.Ibi bituma irusha ubushobozi bwo kurwanya interineti.
4. Urwego ruhanitse cyane: Kubera gukoresha imiyoboro ibiri, kuvanga IQ mubusanzwe bifite intera ndende ishobora guhura nibisabwa bisaba gutunganya ibimenyetso.
IQ ivanga muri rusange ikoreshwa mubice bikurikira:
1. Sisitemu y'itumanaho idafite insinga: IQ ivanga ikoreshwa cyane muri sisitemu y'itumanaho ridafite insinga, harimo sisitemu y'itumanaho rya terefone igendanwa, sisitemu y'itumanaho rya satellite hamwe n'imiyoboro y'akarere idafite umugozi.Byakoreshejwe mu kwerekana ibimenyetso byakiriwe, guhindura ibimenyetso byoherejwe, no kumenya demodulation, modulation hamwe ninshuro zihindura ibimenyetso.
2.Modem: Ivanga rya IQ nibintu byingenzi bikunze kuboneka muri modem zikoreshwa mukuvanga ibimenyetso bya baseband murwego rwa RF kugirango byandurwe, cyangwa kuvanga ibimenyetso bya RF byakiriwe muri baseband kugirango demodulation.
3.Ikwirakwizwa ryihuta ryamakuru: Kuberako IQ ivanga irashobora gukoresha ibimenyetso bya orthogonal, bifite progaramu zingenzi muburyo bwo kohereza amakuru yihuse.Kurugero, muri sisitemu yitumanaho rya optique hamwe n’itumanaho ryihuse rya digitale, QAM modulation na demodulation ukoresheje IQ ivanga irashobora gutuma amakuru yihuta kandi afite ubushobozi bwo kohereza amakuru.
4.Isesengura ryitwara ryabatwara: IQ ivanga IQ irashobora gukoreshwa mugusuzuma kwivanga kwabatwara, bishobora gufasha kumenya inkomoko yo kwivanga no gukuraho intambamyi mugupima no gusesengura icyiciro na amplitude yamakuru yikimenyetso.
QualwaveInc itanga IQ-ivanga akazi kuva 1.75 kugeza 5GHz.
