♠ AFE7799 I-Quad-Channel RF Transceiver Nomzila Wempendulo
I-AFE7799 iyi-transceiver esebenza kahle kakhulu, i-multichannel transceiver, ehlanganisa amaketanga amane aqondile aguqulayo aqonde phezulu, amaketango amane athola phansi aqondiswe phansi, kanye namaketanga amabili e-RF amasampula e-wideband enza amaketanga asizayo (izindlela zokuphendula). Ububanzi obuguquguqukayo obuphezulu be-transmitter namaketanga okwamukela buvumela ukukhiqiza nokwamukela amasiginali we-2G, 3G, 4G, kanye ne-5G eziteshini ezingenantambo. Ukuchithwa kwamandla aphansi nokuhlanganiswa kwamashaneli amakhulu kwenza i-AFE7799 ifaneleke ukubhekana namandla nosayizi ovimbezelwe weziteshi ze-MIMO ze-4G ne-5G ezinkulu. I-wideband kanye nendlela yempendulo yebanga eliguqukayo eliphezulu ingasiza i-digital pre-distortion (DPD) yezikhulisamandla kuchungechunge lokudlulisela. Isivinini esisheshayo se-SerDes singasiza ekwehliseni inani lemizila edingekayo ukuze kudluliswe idatha ngaphakathi nangaphandle.
Iketango ngalinye lomamukeli we-AFE7799 lihlanganisa i-28-dB ye-digital step attenuator (DSA), elandelwa yi-wideband passive IQ demodulator, kanye ne-baseband amplifier enezihlungi ezididiyelwe zokulwa namaphasi aphansi ahlanganisiwe, okushayela i-sigma-delta ADC yesikhathi esiqhubekayo. Iketango le-RX lingathola i-bandwidth esheshayo (IBW) efika ku-200 MHz. Isiteshi ngasinye esamukelayo sinezithonjana ezimbili zamandla aphezulu e-analogi kanye nezihlonzi zamandla edijithali ezihlukahlukene ukuze zisize isilawuli sangaphandle noma sangaphakathi se-AGC esizimele samashaneli amukelayo, kanye nomtshina wokulayisha ngokweqile we-RF wokuvikela ukwethembeka kwedivayisi. I-algorithm ehlanganisiwe ye-QMC (quadrature mismatch compensation) iyakwazi ukuqhubeka iqaphe futhi ilungise ukungafani kokungalingani kwe-rx chain I kanye ne-Q ngaphandle kwesidingo sokujova noma imaphi amasignali athile noma ukwenza ukulinganisa ungaxhunyiwe ku-inthanethi.
Iketango ngalinye lokudlulisela lihlanganisa ama-14-bit, 3-Gsps IQ DACs, alandelwa ukwakhiwa kabusha okuhlelekayo kanye nesihlungi sokwaliwa kwesithombe se-DAC, imoduli ye-IQ.
ukushayela i-wideband RF amplifier ene-39-dB range gain control. I-TX chain edidiyelwe i-QMC kanye ne-LO yokuvuza kwe-algorithms yokukhansela, ukusebenzisa indlela ye-FB ingalandelela njalo futhi ilungise ukungafani kwe-TX chain IQ nokuvuza kwe-LO.
