♠ AFE7799 Quad-Channel RF Transceiver Yokhala Ndi Mayankho Njira
AFE7799 ndi transceiver yogwira ntchito kwambiri, yophatikizira maunyolo anayi otembenuzidwa molunjika, maunyolo anayi olandila molunjika, ndi maunyolo awiri amtundu wa RF omwe amawerengera maunyolo othandizira (njira zoyankha). Mitundu yayikulu yosinthika ya ma transmitter ndi unyolo wolandila imalola kupanga ndi kulandira ma siginecha a 2G, 3G, 4G, ndi 5G pamasiteshoni opanda zingwe. Kuwonongeka kwa mphamvu zochepa komanso kuphatikiza kwamayendedwe akulu kumapangitsa AFE7799 kukhala yoyenera kuthana ndi mphamvu ndi kukula kwa 4G ndi 5G zazikuluzikulu za MIMO. Njira yoyankhira yayikulu komanso yosinthika kwambiri imatha kuthandizira kupotoza kwa digito (DPD) kwa zokulitsa mphamvu mu tcheni chotumizira. Kuthamanga kwa SerDes kungathandize kuchepetsa kuchuluka kwa mayendedwe ofunikira kusamutsa deta mkati ndi kunja.
Unyolo uliwonse wolandila wa AFE7799 umaphatikizapo 28-dB osiyanasiyana digito sitepe attenuator (DSA), kutsatiridwa ndi wideband passive IQ demodulator, ndi baseband amplifier ndi Integrated programmable antialiasing zosefera low pass, kuyendetsa mosalekeza sigma-delta ADC. Unyolo wa RX ukhoza kulandira bandwidth yomweyo (IBW) mpaka 200 MHz. Njira iliyonse yolandirira imakhala ndi zowunikira mphamvu ziwiri za analogi ndi zowunikira zamagetsi zosiyanasiyana kuti zithandizire kuwongolera kwakunja kapena kwamkati kwa AGC kwa mayendedwe olandila, komanso chowunikira cha RF choteteza kudalirika kwa chipangizocho. Ma algorithm ophatikizika a QMC (quadrature mismatch compensation) amatha kuyang'anira mosalekeza ndikuwongolera kusalingana kwa rx chain I ndi Q popanda kufunikira kubaya ma siginecha aliwonse kapena kuchita kusanja kwapaintaneti.
Unyolo uliwonse wa transmitter umaphatikizapo ma 14-bit, 3-Gsps IQ DACs, kutsatiridwa ndi kukonzanso kosinthika komanso fyuluta yokana zithunzi za DAC, moduli ya IQ.
kuyendetsa RF amplifier yokhala ndi 39-dB osiyanasiyana kupeza kuwongolera. Unyolo wa TX wophatikizira ma algorithms a QMC ndi LO leakage kuletsa, kugwiritsa ntchito njira ya FB kumatha kutsata ndikuwongolera kusagwirizana kwa TX chain IQ ndi kutayikira kwa LO.
• Ma transmitters a Quad kutengera kamangidwe kamene kamasintha:
- Kufikira 600 MHz ya RF yopatsira bandwidth pa unyolo uliwonse
