Basa reRF front-end muhurongwa hwekutaurirana

Munzira dzemazuva ano dzekutaurirana, Radio Frequency (RF) front-end inoita basa rakakosha mukugonesa kutaurirana kusina waya kwakanaka. Iri pakati peantenna ne digital baseband, RF front-end ine basa rekugadzirisa masaini anopinda neanobuda, zvichiita kuti ive chinhu chakakosha mumidziyo kubva kumafoni kusvika kumasatellite.

Chii chinonzi RF Front-End?
Nzvimbo yekumberi yeRF ine zvikamu zvakasiyana-siyana zvinobata kugamuchira nekutumirwa kwemasaini. Zvinhu zvakakosha zvinosanganisira ma amplifiers emagetsi (PA), ma amplifiers ane ruzha rwakaderera (LNA), mafirita, uye maswichi. Zvikamu izvi zvinoshanda pamwe chete kuona kuti masaini anotumirwa nesimba rinodiwa uye zvakajeka, ukuwo zvichideredza kupindira uye ruzha.

Kazhinji, zvikamu zvese zviri pakati peantenna neRF transceiver zvinonzi RF front-end, zvichiita kuti chiratidzo che wireless chifambe zvakanaka.

2) Kupatsanura uye Kushanda kweRF Front-End
MaRF front-end anogona kuiswa muzvikamu zviviri zvikuru zvichienderana nechimiro chayo: zvikamu zvakasiyana uye maRF modules. Zvikamu zvakasiyana zvinoiswa muzvikamu zvakare zvichienderana nebasa razvo, nepo maRF modules akakamurwa kuita mazinga ekubatanidza akaderera, epakati, uye epamusoro. Pamusoro pezvo, zvichienderana nenzira yekutumira masaini, RF front-end yakakamurwa kuita nzira dzekutumira nekugamuchira.

Kubva pakupatsanurwa kwemidziyo yakasiyana, zvikamu zvakakosha zveRF front-end zvinosanganisirwa mu power amplifier (PA), duplexer (Duplexer neDiplexer), radio frequency switch (Switch), filter (Filter) uye low noise amplifier (LNA), nezvimwewo. Zvikamu izvi, pamwe chete ne baseband chip, zvinoumba RF system yakakwana.

MaAmplifaya eSimba (PA): Simbisa chiratidzo chiri kutumirwa.
Duplexers: Dzinoparadzanisa masaini ekutumira nekugamuchira, zvichibvumira michina kushandisa antenna imwe chete zvakanaka.
Chinja cheRadio Frequency (Chinja): Batidza kuchinja pakati pekutumira nekugamuchira kana pakati pemabhendi akasiyana efrequency.
Mafirita: Sefa mafrequency asingadiwe uye chengetedza chiratidzo chaunoda.
MaAmplifiers Asina Ruzha (LNA): Wedzera masaini asina simba munzira yekugamuchira.
Mamodule eRF, zvichienderana nedanho rawo rekubatanidza, anotangira pamamodule ekubatanidza akaderera (akadai seASM, FEM) kusvika kumamodule ekubatanidza apakati (akadai seDiv FEM, FEMID, PAiD), uye mamodule ekubatanidza akakwira (akadai sePAMiD, LNA Div FEM). Rudzi rwega rwemodule rwakagadzirirwa kusangana nezvinodiwa zvakasiyana zvekushandisa.

Kukosha muMasisitimu Ekutaurirana
RF front-end chinhu chakakosha chinoita kuti kutaurirana kwe wireless kushande zvakanaka. Inosarudza mashandiro ese esystem maererano nesimba remasaini, mhando, uye bandwidth. Semuenzaniso, muma network efoni, RF front-end inovimbisa kutaurirana kwakajeka pakati pemudziyo ne base station, zvichikanganisa zvakananga kunaka kwekufona, kumhanya kwedata, uye huwandu hwekufukidza.

Mhinduro dzeRF dzeKumberi Kwekupedzisira
Apex inonyanya kugadzira zvikamu zveRF zvepamberi, ichipa mhinduro dzakagadzirirwa kusangana nezvinodiwa zvemasisitimu akasiyana ekutaurirana. Rudzi rwezvigadzirwa zvedu zvepamberi zveRF zvinovimbisa kushanda kwakanaka kwezvishandiso mukutaurirana, muchadenga, kudzivirira, nezvimwewo.

Mhedziso
RF front-end chikamu chakakosha chechero sisitimu yekutaurirana, ichivimbisa kutapurirana kwemasaini uye kugamuchira masaini zvinobudirira uku ichideredza kukanganiswa. Nekufambira mberi kwetekinoroji uye kudiwa kuri kukura kwekushanda kwepamusoro, kukosha kwemhinduro dzeRF front-end dzemhando yepamusoro kuri kuramba kuchikwira, zvichiita kuti dzive chikamu chakakosha muma network emazuva ano asina waya.
