Kōwae pito-mua RF: te kaha matua o te wā 5G

He mea nui te wāhanga mua-mutunga RF (FEM) i roto i ngā whakawhitiwhitinga ahokore o ēnei rā, inā koa i te ao 5G. Ko te nuinga o ngā mea he wāhanga matua pēnei i te whakakaha hiko (PA),tātari,takirua, pana RF mewhakakaha haruru iti (LNA)hei whakarite i te kaha, te pumau me te kounga o te tohu.

Ko te whakakaha hiko te kawenga mō te whakakaha i te tohu RF, inā koa i roto i te 5G, e hiahia ana ki te tino pai me te tino rārangi. Ka tīpakohia e te tātari he tohu auau motuhake hei tātari i ngā tohu pokanoa kia mau ai te parakore o te tuku tohu. I roto i te roopu auau teitei, he painga me ngā ngoikoretanga o ngā tātari ngaru oro mata (SAW) me ngā tātari ngaru oro papatipu (BAW). He pai ake te mahi a ngā tātari BAW i roto i te roopu auau teitei, engari he nui ake te utu.

Tetakiruae tautoko ana i te pūnaha whakawhitiwhiti kōrero auau wehewehe rua (FDD) hei whakarite i te whai huatanga o te whakawhitiwhiti kōrero rua-ara, ko te pana RF te kawenga mō te whakawhiti i te ara tohu, inā koa i roto i te taiao maha-roopu 5G, e hiahia ana kia iti te ngaronga whakaurunga me te whakawhiti tere. Ko tewhakakaha haruru itikia kore ai te tohu ngoikore e whakararuraruhia e te haruru.

I te whanaketanga o te hangarau 5G, kei te neke haere ngā kōwae RF o mua ki te whakaurunga me te whakaitiiti. Ka tākaihia e te hangarau tākai SiP ngā wāhanga RF maha, ka whakapai ake i te whakaurunga me te whakaiti i ngā utu. I taua wā anō, mā te tono o ngā rauemi hou pēnei i te polymer tioata wai (LCP) me te polyimide whakarerekētia (MPI) i roto i te mara pūihi ka whakapai ake i te whai huatanga o te tuku tohu.

Nā te auahatanga o ngā kōwae pito-mua RF kua whakatairanga i te ahunga whakamua o ngā whakawhitiwhiti kōrero 5G, ā, ka haere tonu te whai wāhi nui ki ngā whakawhitiwhiti kōrero ahokore a meake nei, ka nui ake ngā huarahi mō te whanaketanga hangarau.
