♠ AFE7799 Quad-Channel RF Transceiver Ma Ala Fa'amatalaga
O le AFE7799 o se fa'atinoga maualuga, tele-channel transceiver, tu'ufa'atasia fa sa'o i luga-liua filifili transmitter, fa sa'o i lalo-liliu filifili filifili, ma lua wideband RF sampling digitizing filifili fesoasoani (ala manatu). Ole maualuga maualuga ole laina ole transmitter ma receiver e mafai ai ona fa'atupuina ma maua fa'ailoga 2G, 3G, 4G, ma le 5G mo nofoaga fa'avae uaealesi. O le fa'aitiitia o le malosi ma le fa'aogaina o ala tetele e mafai ai e le AFE7799 ona fa'afeso'ota'i le malosi ma le lapo'a fa'atapula'aina 4G ma le 5G tele MIMO nofoaga autu. Ole laina lautele ma le maualuga ole auala fa'aalia e mafai ona fesoasoani ile digital pre-distortion (DPD) ole eletise eletise ile filifili transmitter. Ole saoasaoa o SerDes e mafai ona fesoasoani e faʻaitiitia le numera o laina e manaʻomia e faʻafeiloaʻi ai faʻamatalaga i totonu ma fafo.
O filifili ta'itasi uma o le AFE7799 e aofia ai le 28-dB numera numera la'asaga (DSA), soso'o ai ma le broadband passive IQ demodulator, ma le fa'apipi'i fa'apipi'i fa'atasi ai ma fa'apipi'i fa'apipi'i fa'apipi'i fa'apolokalame fa'apipi'i maualalo pasi, fa'aola le sigma-delta ADC. O le filifili RX e mafai ona maua se bandwidth vave (IBW) e oʻo atu i le 200 MHz. O alavai ta'itasi ta'itasi e iai fa'ata'ita'i eletise e lua fa'atasi ma masini fa'akomepiuta eseese e fesoasoani i le fa'atonu AGC tuto'atasi fafo po'o totonu fo'i mo alavai, ma se su'esu'ega ova RF mo le puipuiga o le fa'atuatuaina o masini. O le QMC faʻatasi (quadrature mismatch compensation) algorithm e mafai ona faʻaauau ona mataʻituina ma faʻasaʻo mo le rx filifili I ma Q le paleni le fetaui e aunoa ma le manaʻomia e tui soʻo se faʻailoga faʻapitoa poʻo le faia o le faʻavasegaina tuusao.
O filifili taʻitasi taʻitasi e aofia ai le 14-bit, 3-Gsps IQ DACs, sosoo ai ma le toe faʻaleleia o le polokalame ma le DAC image rejection filter, se IQ modulator.
fa'aola le fa'amalo RF lautele fa'atasi ma le 39-dB va'aiga maua pule. O le TX filifili ua tu'ufa'atasia le QMC ma le LO leakage fa'aleaogaina algorithms, fa'aogaina le ala FB e mafai ona siaki pea ma fa'asa'o mo le TX filifili IQ mismatch ma LO lekage.
