♠ AFE7799 Quad-Channel RF Transceiver eneNdlela yeNgxelo
I-AFE7799 yindlela esebenza ngayo ephezulu, i-multichannel transceiver, edibanisa amatyathanga amane athe ngqo aguqukayo, amatyathanga amane athe ngqo awamkela uguqulo, kunye neesampulu ezimbini zeRF zesampulu ezenza idijithali amatyathanga ancedisayo (iindlela zeempendulo). Uluhlu oluguquguqukayo oluphezulu lwe-transmitter kunye ne-receiver chain chain luvumela ukuvelisa kunye nokufumana i-2G, i-3G, i-4G, kunye ne-5G yezibonakaliso zezikhululo ezingenazintambo. Ukutshatyalaliswa kwamandla aphantsi kunye nokudityaniswa kweziteshi ezinkulu kwenza i-AFE7799 ilungele ukujongana namandla kunye nobukhulu obunyanzelwayo be-4G kunye ne-5G izikhululo zesiseko se-MIMO ezinkulu. I-wideband kunye noluhlu oluguquguqukayo oluphezulu lwendlela yempendulo inokuncedisa i-digital distortion (DPD) ye-amplifiers yamandla kwi-transmitter chain. Isantya seSerDes esikhawulezayo sinokunceda ukunciphisa inani leendlela ezifunekayo ukudlulisa idatha ngaphakathi nangaphandle.
Ikhonkco ngalinye lomamkeli we-AFE7799 libandakanya i-28-dB uluhlu lwe-digital step attenuator (DSA), ilandelwa yi-wideband passive IQ demodulator, kunye ne-baseband amplifier ene-programmable antialiasing edibeneyo yokucoca i-low pass filters, eqhuba i-sigma-delta ADC eqhubekayo. Ikhonkco le-RX linokufumana i-bandwidth esheshayo (IBW) ukuya kwi-200 MHz. Ijelo ngalinye elamkelayo linezichongi zamandla e-analog encopho ezibini kunye nezixhobo ezahlukeneyo zokubona amandla edijithali ukunceda ulawulo lwangaphandle okanye lwangaphakathi oluzimeleyo lwe-AGC kutshaneli abamkelayo, kunye nesixhobo sokujonga ukulayisha ngaphezulu kwe-RF kukhuseleko lokuthembeka kwesixhobo. I-QMC edibeneyo (i-quadrature mismatch compensation) i-algorithm iyakwazi ukubeka iliso ngokuqhubekayo kunye nokulungisa i-rx chain I kunye ne-Q ukungalingani kokungalingani ngaphandle kwesidingo sokujova nayiphi na imiqondiso ethile okanye ukwenza ukulinganisa ngaphandle kwe-intanethi.
Ikhonkco ngalinye lokuhambisa libandakanya ii-14-bit ezimbini, i-3-Gsps IQ DACs, ilandelwa lulwakhiwo olucwangcisekileyo kunye nesihluzi sokulahlwa komfanekiso weDAC, imodyuli ye-IQ.
ukuqhuba i-wideband RF amplifier ene-39-dB uluhlu lokufumana ulawulo. Ikhonkco le-TX lidityaniswe ne-QMC kunye ne-LO ukuvuza i-algorithms yokurhoxisa, ukuxhamla indlela ye-FB inokuhlala ilandelela kwaye ilungise ukungahambi kakuhle kwe-TX chain IQ kunye nokuvuza kwe-LO.
