I-1 MER ibhekisa kwi-Intrinsic Modulator Extinction Ratio.Umlinganiselo wokutshabalala ophunyeziweyo uqhelekile ngumlinganiselo wokuphela kwemodyuli echazwe kwidatha yemodyuli.
2VumelaVπ bonisa amandla ombane we-bias kwi-180◦ kwayeVP bonisa owona mbane ulungelelanisiweyo wokuthambekela kwiindawo ezineQuad.
3Nceda uqaphele ukuba igalelo lamandla okukhanya alibhekiseli kumandla okukhanya kwindawo ekhethiweyo yokukhetha.Ngawona mandla okukhanya aphezulu apho imodyuli inokuthumelela khona isilawuli xa amandla ombane ecala elicala asuka−Vπ ukuya +Vπ .

1 Ipolar ixhomekeke kwisignali ye-RF yesixokelelwano.Xa kungekho mqondiso weRF kwisixokelelwano, i-polar kufuneka ibe ntle.Xa isignali yeRF ine-amplitude enkulu kunomgangatho othile, i-polar iya kutshintsha ukusuka ku-positive ukuya ku-negative.Ngeli xesha, iNull point kunye nePeak point ziya kutshintshana.Inqaku le-Q + kunye ne-Q-inqaku liya kutshintsha kunye nomnye.Ukutshintsha kwePolar kwenza umsebenzisi atshintshe
polar ngqo ngaphandle kokutshintsha iindawo zokusebenza.
