Te tūranga o te pito mua o te RF i roto i ngā pūnaha whakawhitiwhiti kōrero

I roto i ngā pūnaha whakawhitiwhiti kōrero o ēnei rā, he mea nui te taha mua o te Auautanga Reo Irirangi (RF) hei whakahohe i te whakawhitiwhiti kōrero ahokore whai hua. Kei waenganui i te pūihi me te ara matihiko, ko te taha mua o te RF te kawenga mō te tukatuka i ngā tohu e haere mai ana, e haere atu ana hoki, ā, he wāhanga nui tēnei i roto i ngā taputapu mai i ngā waea atamai ki ngā amiorangi.

He aha te RF Front-End?
Kei roto i te pito o mua o te RF ngā wāhanga maha e whakahaere ana i te whiwhinga me te tuku tohu. Ko ngā wāhanga matua ko ngā whakakaha hiko (PA), ngā whakakaha haruru iti (LNA), ngā tātari, me ngā pana. Ka mahi tahi ēnei wāhanga hei whakarite kia tukuna ngā tohu me te kaha me te mārama e hiahiatia ana, me te whakaiti i te pokanoa me te haruru.

I te nuinga o te wā, ko ngā wāhanga katoa i waenga i te pūihi me te kaitahuri RF ka kiia ko te pito-mua RF, hei whakarite i te tuku tohu ahokore whai hua.

2) Te Whakarōpūtanga me te Mahi o te RF Front-End
E rua ngā momo matua o te pito-mua o te RF, i runga i tōna āhua: ngā wāhanga motuhake me ngā kōwae RF. Ka whakarōpūhia anō ngā wāhanga motuhake i runga i tā rātou mahi, ko ngā kōwae RF ia ka wehea ki ngā taumata whakaurunga iti, waenga, me te teitei. Hei tāpiri, i runga i te ara tuku tohu, ka wehea te pito-mua o te RF ki ngā ara tuku me te ara whiwhi.

Mai i te wehenga mahi o ngā taputapu motuhake, ko ngā wāhanga matua o te pito mua o te RF kua wehea ki te whakakaha mana (PA), te takirua (Duplexer me te Diplexer), te pana auau reo irirangi (Switch), te tātari (Tātari) me te whakakaha haruru iti (LNA), me ētahi atu. Ko ēnei wāhanga, me te maramara turanga, ka hanga he pūnaha RF katoa.

Ngā Whakakaha Mana (PA): Whakakaha i te tohu e tukuna ana.
Ngā Pūihi Takirua: Ka wehea ngā tohu tuku me ngā tohu whiwhi, kia taea ai e ngā pūrere te tohatoha i te pūihi kotahi me te whai hua.
Pana auau reo irirangi (Pāna): Whakahohehia te whakawhiti i waenga i te tuku me te whiwhinga, i waenga rānei i ngā roopu auau rerekē.
Ngā Tātari: Tātarihia ngā auau kāore e hiahiatia, ka pupuri i te tohu e hiahiatia ana.
Ngā Whakakaha Haruru-Iti (LNA): Whakakahangia ngā tohu ngoikore i te ara whiwhi.
Ko ngā kōwae RF, i runga i te taumata whakauru, kei roto i ngā kōwae whakauru-iti (pēnei i te ASM, FEM) ki ngā kōwae whakauru-waenga (pēnei i te Div FEM, FEMID, PAiD), me ngā kōwae whakauru-teitei (pēnei i te PAMiD, LNA Div FEM). Kua hangaia ia momo kōwae kia tutuki ai ngā hiahia tono rerekē.

Te Hiranga i roto i ngā Pūnaha Whakawhitiwhiti Kōrero
Ko te pito mua o te RF te mea matua e āhei ai te whakawhitiwhiti kōrero ahokore whai hua. Mā tēnei ka whakatau i te mahi whānui o te pūnaha e pā ana ki te kaha o te tohu, te kounga, me te whānui o te hononga. Hei tauira, i roto i ngā whatunga waea pūkoro, ka whakarite te pito mua o te RF i te whakawhitiwhiti kōrero mārama i waenga i te taputapu me te teihana turanga, ka pā tika ki te kounga waea, te tere raraunga, me te whānuitanga o te kapinga.

Ngā Otinga Mua RF Ritenga
He tohunga a Apex ki te hoahoa i ngā wāhanga ritenga o mua o te RF, e tuku ana i ngā otinga kua whakaritea kia tutuki ai ngā whakaritenga motuhake o ngā pūnaha whakawhitiwhiti kōrero rerekē. Mā tā mātou whānuitanga o ngā hua RF ka whakarite kia pai ake te mahi mō ngā tono i roto i te whakawhitiwhiti kōrero, te rererangi, te parepare, me te maha atu.

Whakamutunga
He wāhanga nui te pito mua o te RF o tētahi pūnaha whakawhitiwhiti kōrero, e whakarite ana i te tuku me te whiwhinga tohu whai hua, me te whakaiti i te pokanoa. I te whanaketanga o te hangarau me te tipu haere o ngā tono mō te mahi teitei ake, kei te piki haere tonu te hiranga o ngā otinga pito mua o te RF kounga teitei, ā, he wāhanga nui tēnei i roto i ngā whatunga ahokore hou.
