Te Mārama ki ngā Attenuators Ārahi: He Aratohu ki te Whakahaere Tohu RF

He mea nui ngā whakangāwari arataki i roto i ngā tono RF (Auau Reo Irirangi) kua hangaia hei whakaiti i te taumata mana o tētahi tohu me te kore e whakapōturi rawa i tōna āhua ngaru. He mea whakamahi noa ēnei i roto i te whānuitanga o ngā taputapu hiko, pērā i ngā pūnaha whakawhitiwhiti kōrero, ngā taputapu whakamātautau, me ngā taputapu hauora, hei whakahaere i te kaha o te tohu me te ārai i te taumaha rawa o te tohu.

Ko te mahi matua o te whakaitiiti ā-arataki he whakarato i tētahi nui pumau, rerekē rānei o te whakaitiiti, e whakaatuhia ana i roto i ngā tesipere (dB). Ka taea te whakarite i tēnei taumata whakaitiiti mā te whakarerekē i te uara ātete o te whakaitiiti. Ka taea te whakarōpū i ngā whakaitiiti ā-arataki ki ngā momo matua e rua: ngā whakaitiiti pumau me ngā whakaitiiti rerekē.

He taumata whakaitiiti kua whakaritea kētia ngā whakangāwari pūmau, kāore e taea te whakarerekē. He mea whakamahi noa ēnei i roto i ngā tono e hiahiatia ana he taumata whakaitiiti pumau, pērā i ngā whakakaha tohu, i ngā whakaranu rānei. I tētahi atu taha, ka taea e ngā whakangāwari taurangi te whakarerekē i ngā taumata whakaitiiti, kia pai ai mō ngā tono e hiahiatia ana te whakahaere hihiri i te kaha o te tohu.

Ko ngā ātete hiko mata he mea hanga mā te whakamahi i ngā rauemi ātete kounga teitei, pērā i ngā ātete kiriata matotoru, ātete kiriata angiangi rānei, kia tika ai, kia pono ai hoki te mahi. Kei roto i tētahi kete mata, e whakarato ana i te tiakitanga tinana me te whakaurunga ngāwari ki ngā ara iahiko hiko.

I roto i ngā tono RF, he mea nui te mahi a ngā attenuators mata ki te pupuri i te pono o te tohu, te whakaiti i ngā whakaata tohu, me te whakapai ake i te mahi whānui o te pūnaha. He maha ngā wā ka whakamahia ngātahitia ēnei me ētahi atu wāhanga RF, pērā i ngā whakakaha, ngā tātari, me ngā pūihi, hei arotau i te tuku me te whiwhi tohu.

Hei whakamutunga, he mea nui ngā attenuators mata i roto i ngā tono RF e whakarato ana i te mana tika ki te kaha o te tohu, ā, e āwhina ana ki te whakarite kia tika te mahi a ngā taputapu hiko. Nā te maha o ngā whakamahinga me te pono, he mea nui ēnei taputapu mā ngā miihini me ngā kaihoahoa e mahi ana i te mara o te hangarau RF.
