Lammaanaha dhexdhexaadinta hooseeya waa mid si fiican loo naqshadeeyey oo si wax ku ool ah u xakameyn kara qallooca intermodulation, hagaajinta toosan iyo kala duwanaanshaha firfircoon ee nidaamka.Waxay saami ahaan u qoondayn kartaa calaamadaha soo-gelinta laba dekedood oo wax-soo-saarka ah, taas oo hoos u dhigaysa cufnaanta qaybaha aan tooska ahayn waxayna yaraynaysaa suurtogalnimada is-dhexgalka.
Lammaanayaasha isdhexgalka hooseeya waxay ku shaqeyn karaan xaddi badan oo soo noqnoqda waxayna ku habboon yihiin nidaamyada isgaarsiinta wireless-ka ee xadhkaha soo noqnoqda ee kala duwan.Waxay dabooli kartaa baahiyaha isgaadhsiinta ee xadhkaha soo noqnoqda ee kala duwan waxayna ilaalin kartaa waxqabadka isdhexgalka.
Lammaanayaasha dhexdhexaadinta hooseeya waxay caadi ahaan isticmaalaan qaab-dhismeedyada sida xadhkaha microstrip iyo waveguides coplanar, kuwaas oo leh cabbir yar iyo miisaan.Tani waxay fududaynaysaa in la isku xidho oo la qaabeeyo aaladaha bilaa-waayirka ah, badbaadinta meel bannaan, iyo bixinta dabacsanaan nidaam oo wanaagsan.
Lammaanayaasha isdhexgalka hooseeya waxay u adkeysan karaan awoodda wax gelinta sare iyaga oo aan keenin fashilin nidaamka ama hoos u dhaca waxqabadka awoodda sare awgeed.Tani waxay si gaar ah muhiim ugu tahay nidaamyada isgaarsiinta ee awoodda sare leh, taas oo xaqiijin karta isku halaynta iyo xasilloonida nidaamka.
Lammaanayaasha isdhexgalka hooseeya waxay door muhiim ah ka ciyaaraan hababka isgaarsiinta wireless, si wax ku ool ah u xakameynaya qallooca intermodulation iyo hagaajinta waxqabadka nidaamka.Waxqabadkeeda is-dhex-galka ah ee aad u wanaagsan, baaxadda baaxadda baaxadda baaxadda leh, isku-xidhka la hagaajin karo, cabbirka is haysta, iyo dulqaadka sare ee awoodda ayaa ka dhigaysa qayb aan laga maarmi karin oo naqshadeynta iyo hagaajinta nidaamka isgaarsiinta wireless-ka.
