Udindo wa RF front-end mu machitidwe olumikizirana

Mu njira zamakono zolumikizirana, Radio Frequency (RF) front-end imagwira ntchito yofunika kwambiri pothandiza kuti kulumikizana kwa waya kukhale kogwira mtima. Pokhala pakati pa antenna ndi digito baseband, RF front-end imayang'anira kukonza ma signali obwera ndi otuluka, zomwe zimapangitsa kuti ikhale yofunika kwambiri pazida zosiyanasiyana kuyambira mafoni a m'manja mpaka ma satellite.

Kodi RF Front-End ndi chiyani?
Mbali yakutsogolo ya RF ili ndi zigawo zosiyanasiyana zomwe zimagwira ntchito yolandira ndi kutumiza ma signal. Zinthu zofunika kwambiri ndi monga ma power amplifiers (PA), ma low-noise amplifiers (LNA), ma filters, ndi ma switch. Zigawozi zimagwirira ntchito limodzi kuti zitsimikizire kuti ma signal akutumizidwa ndi mphamvu komanso kumveka bwino komwe kukufunika, pomwe akuchepetsa kusokoneza ndi phokoso.

Kawirikawiri, zigawo zonse pakati pa antenna ndi RF transceiver zimatchedwa RF front-end, zomwe zimatsimikizira kutumiza kwa ma signal opanda zingwe bwino.

2) Kugawa ndi Ntchito ya RF Front-End
Ma RF front-end akhoza kugawidwa m'magulu awiri akuluakulu kutengera mawonekedwe ake: zigawo zosiyana ndi ma RF modules. Zigawo zosiyana zimagawidwanso kutengera ntchito yawo, pomwe ma RF modules amagawidwa m'magulu otsika, apakati, ndi apamwamba ophatikizana. Kuphatikiza apo, kutengera njira yotumizira chizindikiro, RF front-end imagawidwa m'njira zotumizira ndi zolandirira.

Kuchokera ku gawo logwira ntchito la zida zosiyana, zigawo zazikulu za RF front-end zikuphatikizidwa mu power amplifier (PA), duplexer (Duplexer ndi Diplexer), radio frequency switch (Switch), filter (Fyuluta) ndi low noise amplifier (LNA), ndi zina zotero. Zigawozi, pamodzi ndi baseband chip, zimapanga dongosolo lonse la RF.

Ma Amplifaya a Mphamvu (PA): Limbitsani chizindikiro chomwe chikutumizidwa.
Ma Duplexers: Amasiyanitsa zizindikiro zotumizira ndi zolandirira, zomwe zimathandiza kuti zipangizo zizigawana bwino antenna imodzi.
Kusinthana kwa ma frequency a wailesi (Sinthani): Yambitsani kusinthana pakati pa kutumiza ndi kulandira kapena pakati pa ma frequency osiyanasiyana.
Zosefera: Sefa ma frequency osafunikira ndikusunga chizindikiro chomwe mukufuna.
Zokulitsa Mphamvu Zochepa (LNA): Kukulitsa zizindikiro zofooka munjira yolandirira.
Ma module a RF, kutengera mulingo wawo wolumikizirana, amayambira pa ma module otsika (monga ASM, FEM) mpaka ma module apakatikati (monga Div FEM, FEMID, PAiD), ndi ma module apamwamba (monga PAMiD, LNA Div FEM). Mtundu uliwonse wa module wapangidwa kuti ukwaniritse zosowa zosiyanasiyana za pulogalamu.

Kufunika kwa Machitidwe Olumikizirana
Ma RF front-end ndi chida chofunikira kwambiri chothandizira kulumikizana bwino kwa opanda zingwe. Chimazindikira momwe makina onse amagwirira ntchito pankhani ya mphamvu ya chizindikiro, mtundu, ndi bandwidth. Mwachitsanzo, m'ma netiweki am'manja, ma RF front-end amatsimikizira kulumikizana bwino pakati pa chipangizocho ndi siteshoni yoyambira, zomwe zimakhudza mwachindunji khalidwe la kuyimba, liwiro la deta, komanso kuchuluka kwa malo omwe angapezeke.

Mayankho Oyambirira a RF Opangidwa Mwamakonda
Apex imagwira ntchito popanga zinthu za RF front-end, zomwe zimapereka mayankho okonzedwa kuti akwaniritse zofunikira za machitidwe osiyanasiyana olumikizirana. Mitundu yathu ya zinthu za RF front-end imatsimikizira magwiridwe antchito abwino kwambiri pakugwiritsa ntchito mauthenga, ndege, chitetezo, ndi zina zambiri.

Mapeto
Ma RF front-end ndi gawo lofunika kwambiri pa njira iliyonse yolumikizirana, kuonetsetsa kuti ma signal atumizidwa bwino komanso kulandiridwa bwino komanso kuchepetsa kusokonezedwa. Chifukwa cha kupita patsogolo kwa ukadaulo komanso kufunikira kwakukulu kwa magwiridwe antchito, kufunika kwa mayankho apamwamba a RF front-end kukupitilira kukwera, zomwe zimapangitsa kuti akhale gawo lofunikira kwambiri pamanetiweki amakono opanda zingwe.
