Milimeter-galu (mmWave) tekinolosi faamama o se vaega taua i le faʻaogaina o fesoʻotaʻiga uaea 5G, ae o loʻo feagai ma le tele o luitau i tulaga o le tino, faʻapalepale gaosiga, ma le mautu o le vevela.
I le malo o fesoʻotaʻiga faʻasalalau 5G, o le lumanaʻi o le a faʻafeiloaʻi i le faʻaogaina o laina i luga aʻe o le 20 GHz i totonu o le mmWave spectrum e faʻaleleia ai le gafatia o le bandwidth, mulimuli ane faʻateleina fua o felauaiga.
Ua lauiloa ona o le maualuga o latou alaleo ma le tele o le leiloa o auala, o faailo mmWave e manaʻomia ai ni antenna laiti. O nei antenna o lo'o fa'apotopoto fa'atasi e fai ai antenna vaapiapi, maualuga-gain array.
O se tasi o fa'afitauli muamua i le mamanu fa'amama o lo'o taoto i le fetuuna'i i le fua o le antenna, aemaise lava mo fa'amama maualuga. E le gata i lea, o le fa'apalepale o le gaosiga ma le mautu o le vevela o filiga e matua'i a'afia ai itu uma o le mamanu ma le gaosiga o oloa.
Fa'agata i le mmWave Tekonolosi
I faiga masani antenna array, o le va i le va o elemene e tatau ona itiiti ifo i le afa o le galu (λ/2) e aloese ai mai le faʻalavelave. O lenei mataupu faavae e tutusa lava le aoga i le 5G beamforming antennas. Mo se faʻataʻitaʻiga, o se antenna o loʻo galue i le 28 GHz band e iai le elemene elemene e tusa ma le 5 mm. O le mea lea, o vaega i totonu o le laina e tatau ona matua laʻititi.
O fa'asologa fa'asolosolo e fa'aaogaina i talosaga mmWave e masani ona fa'aaogaina se mamanu fa'atulagaina, e pei ona fa'aalia i lalo, lea e fa'apipi'i ai antenna (vaega samasama) i luga o laupapa fa'asalalau lolomi (PCBs) (nofoaga lanumeamata), ma laupapa fa'asolo (vaega lanumoana) e mafai ona feso'ota'i fa'asagatonu i le. laupapa antenna.
O le avanoa i luga o nei laupapa matagaluega ua laʻititi lava, ae o loʻo suʻesuʻeina e tekinolosi faʻafou e sili atu le faʻapipiʻiina o fausaga mafolafola, faʻapea o filiga ma isi poloka taʻavale e manaʻomia ona laʻititi laʻititi e faʻapipiʻi saʻo i tua o le antenna PCB.
A'afiaga o Fa'apalepale Gaosia i Fa'amama
Ona o le taua o le mmWave filiga, o le fa'apalepale o gaosiga o lo'o i ai se sao taua, e fa'aaafia uma ai le fa'atinoga ma le tau.
Ina ia suʻesuʻeina atili nei mea, matou te faʻatusatusaina auala faʻapitoa 26 GHz faʻapipiʻi gaosiga:
O le siata o lo'o i lalo o lo'o fa'amatala mai ai tuga fa'apalepale masani e feagai ma le gaosiga:
Fa'apalepale A'afiaga ile PCB Microstrip Filters
E pei ona fa'aalia i lalo, o lo'o fa'aalia se mamanu fa'amama microstrip.
O le mamanu simulation curve e fa'apea:
Ina ia suʻesuʻeina le aʻafiaga o le faapalepale i luga o lenei faamama PCB microstrip, e valu tolerances ono mafai ona filifilia, faʻaalia eseesega iloga.
Fa'apalepale A'afiaga ile PCB Stripline Filters
O le mamanu faamama stripline, o loʻo faʻaalia i lalo, o se fausaga e fitu-vaega ma 30 mil RO3003 laupapa dielectric i luga ma lalo.
O le ta'avale e itiiti ifo le tifato, ma o le coefficient rectangular e maualalo ifo i le microstrip ona o le leai o ni zeros i tafatafa o le passband, e mafua ai le faʻaogaina o le faʻaogaina o le faʻaogaina i laina mamao.
E fa'apena fo'i, o se su'esu'ega fa'apalepale e fa'ailoa mai ai le lagona sili atu pe a fa'atusatusa i laina microstrip.
Fa'ai'uga
Mo le 5G feso'ota'iga uaealesi e maua ai saosaoa, mmWave fa'atekonolosi fa'aogaina i le 20 GHz po'o le maualuga atu o laina e mana'omia. Ae ui i lea, o luʻitau e faʻaauau pea i tulaga o le tino, faʻapalepale mautu, ma faʻalavelave faʻalavelave.
O le mea lea, o le aʻafiaga o faʻapalepale i luga o mamanu e tatau ona mafaufau lelei. O lo'o fa'amaonia mai o fa'amama a le SMT e fa'aalia le mautu tele nai lo le fa'amama fa'ameamea ma le fa'amama laina, e fa'ailoa mai e ono tula'i mai le fa'amama o luga ole mauga ole SMT e fai ma filifiliga fa'apitoa mo feso'ota'iga mmWave i le lumana'i.
