♠ AFE7799 Quad-Channel RF Transceiver leh Jidka Jawaab celinta
AFE7799 waa wax qabad sare, transceiver multichannel, isku dhafka afar silsilado gudbiye toos ah kor u kaca, afar silsilad-soo-beddel toos ah, iyo laba muunad RF ballaaran oo digitizing silsilado caawiye ah (dariiqyada jawaab celinta). Kala duwanaanshaha firfircoonida sare ee gudbiyaha iyo silsiladaha qaataha ayaa u oggolaanaya abuurista iyo helitaanka calaamadaha 2G, 3G, 4G, iyo 5G ee saldhigyada saldhigyada wireless-ka. Korontada yar iyo is dhexgalka kanaalka waaweyn ayaa ka dhigaya AFE7799 ku habboon in wax looga qabto awoodda iyo cabbirka xaddidan ee 4G iyo 5G saldhigyada waaweyn ee MIMO. Dariiqa jawaab celinta ballaadhan iyo baaxadda firfircoon ee sare waxay caawin kartaa qallooca ka hor dhijitaalka ah (DPD) ee cod-weyneyaasha korantada ee silsiladda gudbinta. Xawaaraha SerDes ee degdega ah wuxuu kaa caawin karaa dhimista tirada haadka loo baahan yahay si loogu wareejiyo xogta gudaha iyo dibaddaba.
Silsilad kasta oo qaataha AFE7799 waxaa ku jira 28-dB attenuator tillaabo dhijitaal ah (DSA), oo ay ku xigto IQ demodulator dadban oo ballaaran, iyo cod-weyneeye sal-balaadhan oo leh barnaamij isku-dhafan oo liddi ku ah filtarrada hooseeya, wadista sigma-delta ADC-wakhti joogto ah. Silsiladda RX waxa ay heli kartaa xawli-bandwidwidh degdeg ah (IBW) ilaa 200 MHz. Kanaal kasta oo qaata waxa uu leeyahay laba qalabka ugu sarreeya ee analooga ah iyo qalab sheega koronto oo kala duwan si ay u caawiyaan dibadda ama gudaha iskeed u madax bannaan ee AGC kanaalka qaabilaadda, iyo qalabka xad-dhaafka ah ee RF ee ilaalinta isku hallaynta aaladda. Isku-dhafka QMC (magdhowga quadrature mismatch) algorithm wuxuu awood u leeyahay inuu si joogto ah ula socdo oo u saxo isku-dheellitir la'aanta silsiladda rx I iyo Q iyada oo aan loo baahnayn in la isku duro calaamado gaar ah ama la sameeyo hagaajinta khadka tooska ah.
Silsilad kasta oo gudbiye waxaa ku jira laba 14-bit, 3-Gsps IQ DACs, oo ay ku xigto dib-u-dhiska barnaamijka iyo shaandhada sawirka DAC, modulator IQ
Wadista cod-weyneeye RF-ballaaran oo leh 39-dB oo kontorool faa'iido leh. Silsiladda TX ee isku dhafan QMC iyo LO leakage algorithms, ka faa'iidaysiga dariiqa FB waxay si joogto ah ula socon kartaa oo u saxi kartaa isku-dheellitir la'aanta silsiladda TX ee IQ iyo daadinta LO.
