♠ AFE7799 Quad-Channel RF Transceiver Nrog Txoj Kev Tawm Tsam
AFE7799 yog ib qho kev ua tau zoo, multichannel transceiver, integrating plaub direct up-conversion transmitter chains, plaub ncaj down-conversion receiver chains, thiab ob wideband RF sampling digitizing auxiliary chains (feedback paths). Qhov siab dynamic ntau ntawm cov transmitter thiab receiver chains tso cai rau tsim thiab tau txais 2G, 3G, 4G, thiab 5G signals rau wireless base stations. Lub zog qis qis thiab kev sib txuas loj loj ua rau AFE7799 tsim nyog los hais txog lub zog thiab qhov loj me uas txwv 4G thiab 5G loj MIMO chaw nres tsheb. Txoj kev dav dav thiab siab dynamic ntau txoj kev tawm tswv yim tuaj yeem pab cov digital pre-distortion (DPD) ntawm lub hwj chim amplifiers nyob rau hauv lub transmitter saw. SerDes ceev ceev tuaj yeem pab txo tus lej ntawm txoj kab uas yuav tsum tau hloov cov ntaub ntawv hauv thiab tawm.
Txhua tus txais xov tooj ntawm AFE7799 suav nrog 28-dB ntau yam digital step attenuator (DSA), ua raws li qhov dav dav passive IQ demodulator, thiab lub tshuab hluav taws xob baseband nrog kev sib xyaw ua ke ntawm kev siv tshuaj tiv thaiv kev lim dej qis, tsav tsheb mus tas li sigma-delta ADC. RX saw tuaj yeem tau txais ib qho bandwidth instantaneous (IBW) txog 200 MHz. Txhua lub receiver channel muaj ob lub ntsuas hluav taws xob zoo tshaj plaws thiab ntau lub tshuab hluav taws xob digital los pab rau sab nraud lossis sab hauv kev tswj hwm tus kheej AGC rau cov neeg txais cov channel, thiab RF overload detector rau kev tiv thaiv kev ntseeg tau. Kev sib xyaw QMC (quadrature mismatch them nyiaj) algorithm muaj peev xwm los saib xyuas thiab kho rau rx saw I thiab Q tsis sib haum xeeb yam tsis tas yuav tsum tau txhaj cov cim tshwj xeeb lossis ua haujlwm offline calibration.
Txhua lub tshuab xa xov hluav taws xob suav nrog ob lub 14-ntsis, 3-Gsps IQ DACs, ua raws li kev tsim kho dua tshiab thiab DAC cov duab tsis lees paub lim, IQ modulator
tsav lub wideband RF amplifier nrog 39-dB ntau yam nce tswj. TX chain integrated QMC thiab LO leakage cancellation algorithms, leveraging the FB path can always track and correct for TX chain IQ mismatch and LO to.
