Lau'ele'ele Mauga Baluns RF Microwave Milimita Galu mm galu
Surface Mount Baluns (Balance-Unbalance transformers) o vaega faʻapitoa RF / microwave ua fuafuaina e faʻaliliu i le va o faʻailoga eletise paleni ma le le paleni i taʻavale maualuga. O lo'o gaosia i le fa'aaogaina o ata manifinifi po'o le tele-layer ceramic technologies, o nei masini fa'akomepiuta e tu'uina atu ai suiga taua o le impedance ma le agava'a fa'afiti masani. I le avea ai ma poloka faufale taua i faiga uaealesi, latou te faafaigofieina le sa'o lelei o faailoilo a'o mulimulita'i i faiga fa'aonaponei otometi fa'apotopotoga. O la latou mamanu i luga o le mauga e lelei ai mo le gaosiga maualuga i luga o fesoʻotaʻiga, IoT, ma faʻaoga eletise faʻatau.
Vaega Autu ma uiga:
1. Fa'atinoga maualuga ma fa'ainisinia sa'o
Fa'agaoioi ole alalaupapa: Lagolago le tele o laina alapine (mai le tele o MHz i le tele-GHz bands) fa'atasi ai ma le fa'atinoina faifaipea i luga o bandwidth fa'apitoa, fa'ate'aina le mana'omia mo le tele o vaega va'ai.
Suiga sa'o o le impedance: Tu'u sa'o fua fa'atatau o le fa'aliliuga (fa'ata'ita'iga, 1:1, 1:4, 4:1) fa'atasi ai ma le fa'apalepale mau (± 5% masani) e fetaui ma mana'oga fa'a-vaega ma fa'ai'uga tasi.
Fa'atatau lelei ole amplitude/vaega: Fa'atumauina le paleni maualuga maualuga (e masani lava ± 0.5 dB) ma le paleni vaega (e masani lava ± 5 tikeri) mo le fa'afitia lelei o le pisa masani masani.
Fa'amau maualalo gau: Ausia fa'ailo fa'alilolilo la'ititi (i lalo ifo o le 0.5 dB e fa'atatau i taimi) e ala i le fa'aogaina o le fa'aogaina fa'amaneta ma mea fa'aeletise e maualalo le leiloa.
2. Fa'apipi'i maualuluga ma mafai fa'atasi
Fa'ailoga fa'apitoa: E maua i pusa fa'ata'atia fa'a alamanuia ma lapopo'a fa'aleaganu'u mo mamanu fa'atapula'aina avanoa.
Fegalegaleaiga i luga o le mauga: Faʻatasi ma mea faʻapipiʻi faʻapipiʻi-ma-nofoaga ma faʻagasologa toe faʻafefeteina, faʻatagaina le gaosiga maualuga.
Fau malosi: Fa'aaogā mea fa'amea, ferrite, po'o mea fa'aputu fa'atasi ma fa'auma fa'amutaina (Ni/Sn, Au) talafeagai mo tulaga faigata o le si'osi'omaga.
ESD ma le puipuiga o le vevela: O mea fa'apipi'i fa'apipi'i e fa'afeagai ma fa'alavelave ESD (e o'o atu i le 2kV HBM) ma le vevela fa'aoga.
3. Faʻaleleia le faʻamaoni ma le faʻaogaina-faʻapitoa faʻapitoa
Tulaga maualuga le fa'aesea: Tu'u le fa'apito i le uafu e masani lava ona sili atu i le 20 dB e taofia ai le fa'aogaina o fa'ailoga e le mana'omia.
Malosiaga e taulima ai le malosi: Lagolago le maualuga o le eletise mai milliwatts i le tele o watts e fuafua i le tele o afifi ma le mamanu.
Fa'ata'ita'iga fa'apitoa: E maua i fa'atonuga fa'apitoa mo fa'aoga fa'apitoa (Wi-Fi, telefoni feavea'i, Bluetooth, ma isi) fa'atasi ai ma fa'ailoga S-parameters.
Talosaga:
1. Faiga feso'ota'iga uaealesi
Atina'e feavea'i: Transceivers nofoaga autu, masini MIMO tetele, ma sela laiti e manaʻomia ai le faʻafetauiina o le impedance ma le faʻaaogaina masani i RF pito i luma.
Wi-Fi/Bluetooth modules: Fa'agaoioi feso'ota'iga antenna ese'ese ma fa'aleleia le fa'alogoina o le tali i le 2.4/5/6 GHz fa'alava.
5G NR meafaigaluega: Faʻafaigofie le mmWave ma lalo ifo-6 GHz faʻailoga faʻailoga i masini faʻaoga ma atinaʻe fesoʻotaʻiga.
2. Fa'atau mea fa'akomepiuta ma masini IoT
Telefonitelefoni/Tulafono: Fa'ataga le fa'atulagaina o le vaega RF fa'apena ma fa'aleleia le fa'amaoni o fa'ailoga mo le telefoni feavea'i, Wi-Fi, ma GPS e talia.
Mea fa'aeletonika fa'alavalava: Tu'u mai ni fa'ai'uga fa'aliliuga fa'ailo laiti mo le mata'ituina o le soifua maloloina ma fa'aoga feso'ota'iga.
Meafaigaluega atamai fale: Lagolago le feso'ota'iga uaealesi ile IoT sensors, hubs, ma fa'atonu e mana'omia le fa'atinoina o le RF fa'alagolago.
3. Mea faigaluega su'ega ma fua
