M'njira zamakono zoyankhulirana, Radio Frequency (RF) kutsogolo-kumapeto kumagwira ntchito yofunika kwambiri kuti athe kulumikizana popanda zingwe. Yoyikidwa pakati pa mlongoti ndi basband ya digito, RF kutsogolo-kumapeto kumakhala ndi udindo wokonza ma siginecha omwe akubwera ndi otuluka, ndikupangitsa kuti ikhale gawo lofunikira pazida kuyambira mafoni mpaka ma satellite.
Kodi RF Front-End ndi chiyani?
Kumapeto kwa RF kumakhala ndi magawo osiyanasiyana omwe amalandila kulandira ndi kutumiza. Zinthu zazikuluzikulu zikuphatikiza zokulitsa mphamvu (PA), amplifiers otsika phokoso (LNA), zosefera, ndi zosinthira. Zigawozi zimagwira ntchito limodzi kuti zitsimikizire kuti zizindikiro zimafalitsidwa ndi mphamvu zomwe zimafunidwa komanso zomveka bwino, ndikuchepetsa kusokoneza ndi phokoso.
Nthawi zambiri, zonse zomwe zili pakati pa tinyanga ndi transceiver ya RF zimatchedwa RF kutsogolo-kumapeto, kuwonetsetsa kuti ma siginecha opanda zingwe akuyenda bwino.
2) Gulu ndi Ntchito ya RF Front-End
Kumapeto kwa RF kumatha kugawidwa m'mitundu iwiri ikuluikulu kutengera mawonekedwe ake: zigawo za discrete ndi ma module a RF. Zigawo zodziwika bwino zimagawidwanso motengera ntchito yawo, pomwe ma module a RF amagawidwa m'magulu otsika, apakatikati, komanso ophatikizika kwambiri. Kuphatikiza apo, kutengera njira yotumizira ma siginecha, kutsogolo kwa RF kumagawika m'njira zotumizira ndi kulandira.
Kuchokera pagawo logwira ntchito la zida za discrete, zida zazikulu zakutsogolo za RF zikuphatikiza zogawika kukhala amplifier yamagetsi (PA), duplexer (Duplexer ndi Diplexer), switch frequency radio (Switch), fyuluta (Sefa) ndi amplifier ya phokoso lotsika (LNA), etc.,. Zidazi, pamodzi ndi baseband chip, zimapanga dongosolo lathunthu la RF.
Magetsi Amplifiers (PA): Limbikitsani chizindikiro chomwe chikufalitsidwa.
Ma Duplexers: Olekanitsa ma siginecha opatsira ndi olandirira, kulola zida kugawana mlongoti womwewo moyenera.
Kusintha kwa mawayilesi (Sinthani): Yambitsani kusinthana pakati pa kutumiza ndi kulandila kapena pakati pa ma frequency osiyanasiyana.
Zosefera: Sefa ma frequency osafunikira ndikusunga chizindikiro chomwe mukufuna.
Low-Noise Amplifiers (LNA): Kwezani ma siginecha ofooka panjira yolandirira.
Ma module a RF, kutengera mulingo wawo wophatikizira, amachokera ku ma module ophatikizika (monga ASM, FEM) kupita ku ma module ophatikizika (monga Div FEM, FEMID, PAiD), ndi ma module apamwamba kwambiri (monga PAMiD, LNA Div FEM). ). Mtundu uliwonse wa module umapangidwa kuti ukwaniritse zosowa zosiyanasiyana zamagwiritsidwe.
Kufunika kwa Njira Zolumikizirana
Kumapeto kwa RF ndikothandizira kwambiri kulumikizana kopanda zingwe. Zimatsimikizira momwe dongosolo lonse limagwirira ntchito potengera mphamvu ya siginecha, mtundu, ndi bandwidth. Mu ma netiweki am'manja, mwachitsanzo, kutsogolo kwa RF kumatsimikizira kulumikizana momveka bwino pakati pa chipangizocho ndi siteshoni yoyambira, zomwe zimakhudza mwachindunji kuyimba kwa mafoni, kuthamanga kwa data, komanso kufalikira.
Custom RF Front-End Solutions
Apex imagwira ntchito popanga zida zakutsogolo za RF, zomwe zimapereka mayankho ogwirizana ndi zofunikira zamakina osiyanasiyana olankhulirana. Zogulitsa zathu zam'tsogolo za RF zimatsimikizira kuti magwiridwe antchito atelecommunication, mlengalenga, chitetezo, ndi zina zambiri.
Mapeto
Kumapeto kwa RF ndi gawo lofunikira pamakina aliwonse olankhulirana, kuwonetsetsa kuti ma siginecha akuyenda bwino ndikulandila ndikuchepetsa kusokoneza. Ndi kupita patsogolo kwaukadaulo komanso kufunikira kwa magwiridwe antchito apamwamba, kufunikira kwa mayankho apamwamba a RF akutsogolo kukupitilira kukwera, kuwapangitsa kukhala gawo lofunikira pama network amakono opanda zingwe.
