Leitio ala (RF) & masini microwave ua faauigaina o se ituaiga o faamama faaeletonika, lea ua mamanuina e faagaoioia i luga o faailoilo i le megahertz i le gigahertz laina alapine (medium frequency to very high frequency). Ole tele ole fa'amama ole fa'aogaina ole tele ole fa'asalalauga ole leitio, televise, feso'ota'iga uaealesi (telefoni feavea'i, Wi-Fi, ma isi), ma o le tele o masini RF ma microwave o le a aofia ai se ituaiga o fa'amama i luga o fa'ailoga e tu'uina atu pe maua. O ia filiga e masani ona faʻaaogaina e fai ma poloka faufale mo duplexers ma diplexers e tuʻufaʻatasia pe tuueseese ai le tele o faʻaupuga.
Galuega:
1. Rf faamama e mafai ona faʻaitiitia le faʻalavelave faʻafefe ma faʻaleleia le faʻatinoga o meafaigaluega faʻatasi.
2. O le fa'amama RF e fa'atagaina ai na'o le alaleo ma le ala o lo'o fa'asalalauina pe maua e pasi ma fa'aitiitia fa'alavelave fa'ailo i fafo atu o le alalaupapa.
I luga o le faʻavae o lana galuega, e tusa ai ma le tele o taimi o le faʻailoga galue e faʻavasega ai filiga RF, e masani ona vaevaeina i ni vaega se fa, o lona uiga, faʻamama pasi maualalo (LPF), pasi pasi maualuga (HPF), faʻamalo pasi ( BPF) ma fa'amama taofi fa'aili (BSF).
1. Low-pass filter : E faasino i le faamama lea e mafai ai ona pasi le faailo maualalo ae le mafai ona pasia le faailo maualuga;
2. High-pass filter: O le faʻafeagai, o lona uiga, e mafai ona pasia faʻailoga maualuga ma e le mafai ona pasia faʻailoga maualalo;
3. Band-pass filter: E faʻasino i le faʻasolosolo i se faʻasologa masani o faʻailoga e mafai ona pasi, RF faʻamama ma fafo atu ole laina ole laina ole faʻailoga e le mafai ona pasia;
4. Fa'amama-stop filter: O le fa'atinoga o le fa'amama fa'aupu-stop o le fa'afeagai, o lona uiga, o fa'ailo i totonu o se laina fa'aili e poloka, ae o fa'ailo i fafo atu o lenei laina fa'alava e fa'atagaina e ui atu;
RF filiga e mafai ona faʻavasegaina i le SAW filter, BAW filter, LC filter, cavity filter, ceramic filter e tusa ai ma le fausaga poʻo mea o latou foi.
Jingxin, o le tagata tomai faapitoagaosiga o vaega passive RF, e mafai ona ofoina atu RF filiga o loʻo i luga mo faʻamatalaga, lea o loʻo atinaʻe sili atu i le 10 tausaga e mamanuina ma gaosia RF filiga mo faʻaoga eseese, e pei o le DAS solution, BAD system, fesoʻotaʻiga a le militeri, ma maua ai le tele o viiga maualuga mo le ausia mai le tagata fa'atau. E mafai ona faia e Jingxin le faʻavasegaina o mamanu faʻapitoa, e sili atu fesili e talia.
