IQ Mixers RF Microwave Millimeter Wave High Frequency Radio
Microwave Mixers imhando yakakosha yemusanganisi ine maviri anopindirana echikamu masaini nzira anonzi "In-phase" (I) uye "Quadrature" (Q). Maitiro ayo ndeaya anotevera:
1. Ipa ruzivo rwechikamu uye amplitude: Nekuda kwekubatanidzwa kweI uye Q chiteshi, radio frequency IQ mixer inogona 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 yeRF musanganiswa inokwanisa kugadzirisa orthogonal masaini, kureva, masaini ane chikamu musiyano we90 madhigirii. Izvi zvinoita kuti redhiyo frequency musanganisi ibatsire zvakanyanya mune akawanda modulation uye demodulation matekiniki, akadai orthogonal frequency division kuwanda kuwana (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: Millimeter wave mixer inoshandiswa zvakanyanya mumagetsi ekukurukurirana asina waya, kusanganisira nhare 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 masiginecha muRF renji yekutapurirana, kana kusanganisa anogashirwa masaini eRF mubaseband kuti demodulation.
3.High-speed data transmission: Nemhaka yokuti IQ mixers inogona kubata zviratidzo zve orthogonal, vane zvikumbiro zvakakosha mukufambisa kwemashoko makuru. Semuenzaniso, mune optical communication systems uye high-speed digital communications, QAM modulation uye demodulation uchishandisa IQ mixers inogona kugonesa kukurumidza-kumhanya uye yepamusoro-soro yekufambisa data.
4.Carrier interference analysis: IQ mixers inogona kushandiswa pakuongorora kukanganiswa kwemutakuri, 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 26GHz.
