IQ Mixers RF Microwave Millimeter Move High Frequency Radio

Isku-darka Microwave-ka waa nooc gaar ah oo isku-darka ah oo ka kooban laba waddo oo calaamadayn ah oo is-waafajin ah oo loo yaqaan "In-phase" (I) iyo "Quadrature" (Q). Astaamihiisa waa sidan soo socota:

1. Bixi macluumaadka wejiga iyo mugga: Sababtoo ah ku darista kanaallada I iyo Q, isku-darka IQ ee soo noqnoqda raadiyaha ayaa bixin kara macluumaadka wejiga iyo mugga ee calaamadda. Tani waxay muhiim u tahay nidaamyada isgaarsiinta wireless-ka badan iyo hababka wax-ka-beddelka iyo dejinta.
2. Garwaaqso habaynta calaamadaha orthogonal: Kanaallada I iyo Q ee isku-darka RF waxay awood u leeyihiin inay farsameeyaan calaamadaha orthogonal, taas oo ah, calaamadaha leh farqiga wejiga ee 90 darajo. Tani waxay ka dhigaysaa isku-darka soo noqnoqda raadiyaha mid aad waxtar ugu leh farsamooyin badan oo wax-ka-beddelid iyo dib-u-habayn, sida qaybinta soo noqnoqoshada orthogonal frequency division multiple access (OFDM) iyo modulation amplifyation quadrature (QAM).
3. Faragelinta dhegeysiga oo yaraatay: Isku-darka IQ wuxuu awood u leeyahay inuu kala saaro calaamadaha iyo faragelinta iyadoo lagu darayo laba waddo oo is-waafaqsan. Tani waxay ka dhigaysaa mid awood badan u leh inay ka hortagto faragelinta dhegeysiga.
4. Kala duwanaansho firfircoon oo sare: Sababtoo ah isticmaalka laba kanaal, isku-darka IQ waxay caadi ahaan leeyihiin kala duwanaansho firfircoon oo sare oo dabooli karta codsiyada farsamaynta calaamadaha ee adag.
