Igihuza SMA, mu buryo bugufi ni Sub-Miniature Version A, ni igihuza c'incuro nyinshi z'iradiyo gikoreshwa cane mu bikoresho vy'itumanaho bitagira amashanyarazi. Ifasha mu gutanga incuro zishika kuri 18GHz, irafise ubushobozi bwiza bwo guhuza impedance n’ugushikama kw’ikimenyetso, kandi ikoreshwa cane mu bice vya Wi-Fi, mu ma antene ya GPS, no mu maradiyo y’imirongo miremire. Kubera ubunini bwayo bukomeye, uburambe bwayo, n’uguhuza kwayo kwizigirwa, yacitse bumwe mu buryo bwo guhuza bushimwa cane n’abakunzi b’amaradiyo y’ivy’ubuhinga bwa none.
Ku bijanye n'uburyo bw'amajwi y'imirongo miremire, ukwizigirwa kw'ibarabara ni ikintu gihambaye cane kugira ngo umuntu ashobore kwakira neza ibimenyetso vy'urugendo rurerure-. Amaze kugerageza uburyo bwinshi bwo gufatanya, amaherezo hatowe umufatanyabikorwa w’umugore wa SMA afise imyobo ine-. Itera canecane neza ku gipfukisho c’icuma kandi irabuza neza ko ikimenyetso gihungabana. Iyi nzira y’ugufatanya SMAKFD4 ifise insulator ya 4mm irahuye n’imirongo itandukanye, irasodera neza ata n’imwe inyerera, kandi igishushanyo c’isahani y’inzira y’inzira ituma gukosora vyoroha. Igihe nyene izo nkoko zikomeye, iyo nzira yose iraheza yumva ihagaze neza. Amaze kuyifatanya n’antene y’i muhira, ugusobanuka kw’ukwakira kuratera imbere cane; mbere n’ibibanza vyo kure vy’amajwi magufi birashobora kwumvikana neza ku mugoroba. Ku bakunda gukorana n’amaradiyo, umufatanyabikorwa w’igitsina gore SMA yizigirwa arashobora vy’ukuri gushiramwo uburyo bwose bw’umugambi.
