RF Yakakwira Isolation BroadBand Frequency Converters IQ Mixers
IQ Mixers imhando yakakosha yemusanganisi ine nzira mbiri dzinopindirana dzechiratidzo dzinodaidzwa kuti "In-phase" (I) uye "Quadrature" (Q).Maitiro ayo ndeaya anotevera:
1. Ipa ruzivo rwechikamu uye amplitude: Nekuda kwekubatanidzwa kweI uye Q chiteshi, IQ musanganiswa anogona kupa zvese chikamu uye amplitude ruzivo rwechiratidzo.Izvi zvakakosha kune akawanda mawaya ekutaurirana masisitimu uye modulation uye demodulation maitiro.
2. Ziva orthogonal signal processing: Iyo I neQ migero yeIQ mixer inokwanisa kugadzirisa orthogonal zviratidzo, kureva, zviratidzo zvine chikamu chakasiyana che90 degrees.Izvi zvinoita kuti zvive zvakakosha mune dzakawanda modulation uye demodulation matekiniki, akadai orthogonal frequency division multiple access (OFDM) uye quadrature amplitude modulation (QAM).
3. Kuderedza kupindira kwekuteerera: IQ musanganisi inokwanisa kuparadzanisa chiratidzo uye kupindira kwehuwandu nekuda kwekubatanidzwa kwezvikamu zviviri zvinopindirana.Izvi zvinoita kuti iwedzere kukwanisa kupikisa kupindira kwekuteerera.
4. High dynamic range: Nekuda kwekushandiswa kwematanho maviri, IQ mixers inowanzova nepamusoro-soro ine simba inogona kusangana neinoda zviratidzo zvekugadzirisa zvikumbiro.
IQ musanganiswa inowanzo shandiswa mune zvinotevera zvinhu:
1.Wireless communication systems: IQ mixer inoshandiswa zvakanyanya mumagetsi ekukurukurirana asina waya, kusanganisira nharembozha dzekukurukurirana, satellite communication systems uye wireless local area network.Iyo inoshandiswa kudzora iyo yakagamuchirwa chiratidzo, kuenzanisa iyo yakatumirwa chiratidzo, uye kuona iyo demodulation, modulation uye frequency kutendeuka kwechiratidzo.
2.Modem: IQ mixers ndiwo akakosha anowanikwa mumamodemu anoshandiswa kusanganisa baseband masaini muRF renji yekutapurirana, kana kusanganisa yakagamuchirwa masaini eRF mubaseband yedemodulation.
3.High-speed data transmission: Nemhaka yokuti IQ mixers inogona kubata zviratidzo zve orthogonal, vane zvikumbiro zvakakosha mukufambisa kwemashoko makuru.Semuenzaniso, mune optical communication system uye yakakwirira-kumhanya yedhijitari kutaurirana, QAM modulation uye demodulation uchishandisa IQ mixers inogona kugonesa kukurumidza-kumhanya uye yakakwirira-inogonesa data data.
4.Carrier interference analysis: IQ mixers inogona kushandiswa pakuongorora kukanganiswa kwevatakuri, iyo inogona kubatsira kuziva kwakabva kupindira uye kubvisa kupindira nekuyera uye kuongorora chikamu uye amplitude ruzivo rwechiratidzo.
QualwaveInc. inopa IQ-mixers inoshanda kubva ku1.75 kusvika ku5GHz.
