♠ AFE7799 Quad-Channel RF Transceiver Ka Tsela ea Maikutlo
AFE7799 ke transceiver e sebetsang hantle haholo, e kopanyang liketane tse 'ne tse fetolelang ka kotloloho, liketane tse' nè tse amohelang ka kotloloho, le liketane tse peli tse pharalletseng tsa RF tse kopanyang liketane tse thusang (litsela tsa maikutlo). Mefuta e phahameng e matla ea liketane tsa transmitter le receiver e lumella ho hlahisa le ho amohela lipontšo tsa 2G, 3G, 4G, le 5G bakeng sa liteishene tse se nang mohala. Phallo e tlase ea matla le ho kopanngoa ha liteishene tse kholo ho etsa hore AFE7799 e lokele ho sebetsana le matla le boholo ba liteishene tse kholo tsa MIMO tsa 4G le 5G. Tsela ea ho fana ka maikutlo a marang-rang a pharaletseng le a matla a phahameng a ka thusa ho kheloha pele ho digital (DPD) ea li-amplifiers tsa motlakase ka har'a ketane ea transmitter. Lebelo le potlakileng la SerDes le ka thusa ho fokotsa palo ea litselana tse hlokahalang ho fetisetsa data ho tsoa le ho tsoa.
Ketane e 'ngoe le e' ngoe ea moamoheli ea AFE7799 e kenyelletsa 28-dB range digital step attenuator (DSA), e lateloe ke wideband passive IQ demodulator, le baseband amplifier e nang le li-filters tse kopaneng tse antialiasing tse tlase, tse tsamaisang sigma-delta ADC ea nako e tsoelang pele. Ketane ea RX e ka fumana bandwidth ea hang-hang (IBW) ho fihla ho 200 MHz. Seteishene se seng le se seng sa moamoheli se na le lisebelisoa tse peli tsa analoge tsa tlhoro ea matla le lisebelisoa tse fapaneng tsa motlakase tsa dijithale ho thusa taolo ea AGC ea kantle kapa ea kahare e ikemetseng bakeng sa liteishene tse amohelang, le sebui sa RF overload bakeng sa ts'ireletso ea ts'epo ea sesebelisoa. QMC e kopantsoeng (quadrature mismatch compensation) algorithm e khona ho lekola le ho lokisa ho se leka-lekane ha ketane ea rx I le Q ntle le tlhoko ea ho kenya matšoao a itseng kapa ho etsa calibration kantle ho marang-rang.
Ketane e 'ngoe le e' ngoe ea li-transmitter e kenyelletsa li-14-bit, 3-Gsps IQ DACs, tse lateloang ke moralo o hlophisitsoeng le mochini oa ho hana litšoantšo oa DAC, modulator ea IQ.
ho khanna RF amplifier e nang le 39-dB mefuta e mengata ea ho fumana taolo. The TX ketane e kopantseng QMC le LO leakage cancellation algorithms, ho sebelisa tsela ea FB e ka lula e latela le ho lokisa ho se lumellane ha TX chain IQ le LO leakage.
