♠ AFE7799 Quad-Channel RF Transceiver me ke ala pane
ʻO ka AFE7799 kahi transceiver multichannel hana kiʻekiʻe, e hoʻohui ana i ʻehā mau kaulahao transmitter up-conversion pololei, ʻehā mau kaulahao hoʻohuli hoʻololi pololei i lalo, a me ʻelua wideband RF sampling digitizing auxiliary kaulahao (ala ala pane). ʻO ka laulā kiʻekiʻe o ka mea hoʻouna a me nā kaulahao mea hoʻokipa e hiki ai ke hana a loaʻa i nā hōʻailona 2G, 3G, 4G, a me 5G no nā kahua kahua uila. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka hoʻohui ʻana i nā kahawai nui i kūpono i ka AFE7799 e hoʻoponopono i ka mana a me ka nui i kāohi ʻia ʻo 4G a me 5G nui MIMO base station. Hiki i ke ala ākea ākea a me ke kiʻekiʻe dynamic range manaʻo manaʻo ke kōkua i ka digital pre-distortion (DPD) o nā mana amplifiers i ke kaulahao transmitter. Hiki i ka wikiwiki SerDes wikiwiki ke kōkua i ka hōʻemi ʻana i ka nui o nā ala e pono ai e hoʻoili i ka ʻikepili i loko a i waho.
Loaʻa i kēlā me kēia kaulahao mea hoʻokipa o ka AFE7799 he 28-dB digital step attenuator (DSA), a ukali ʻia e ka wideband passive IQ demodulator, a me ka baseband amplifier me nā kānana kaila haʻahaʻa antialiasing programmable, e hoʻokele ana i ka sigma-delta ADC mau manawa. Hiki i ke kaulahao RX ke loaʻa i ka bandwidth koke (IBW) a hiki i 200 MHz. Loaʻa i kēlā me kēia kaila hoʻokipa ʻelua mau mea ʻike mana kikohoʻe analog a me nā mea ʻike mana kikohoʻe like ʻole e kōkua i kahi mana AGC kūʻokoʻa kūwaho a i loko paha no nā kahawai hoʻokipa, a me kahi mea ʻike hoʻonui RF no ka pale ʻana i ka pono o ka hāmeʻa. ʻO ka algorithm QMC (quadrature mismatch compensation) i hoʻohui ʻia e hiki ke nānā mau a hoʻoponopono i ke kaulahao rx I a me Q imbalance mismatch me ka ʻole o ka hoʻokomo ʻana i nā hōʻailona kikoʻī a i ʻole ka hana ʻana i ka calibration offline.
Loaʻa i kēlā me kēia kaulahao transmitter ʻelua 14-bit, 3-Gsps IQ DACs, a ukali ʻia e kahi hana hou programmable a me ka kānana hōʻole kiʻi DAC, kahi modulator IQ.
ke kaʻa ʻana i kahi mea hoʻonui RF wideband me 39-dB range gain control. Ua hoʻohui pū ʻia ke kaulahao TX QMC a me LO leakage cancellation algorithms, me ka hoʻohana ʻana i ke ala FB hiki ke hahai mau a hoʻoponopono no ka TX kaulahao IQ mismatch a me LO leakage.
• Nā mea hoʻolele ʻehā e pili ana i ka hoʻolālā hoʻololi pololei.
- A hiki i ka 600 MHz o RF i hoʻouna i ka bandwidth i kēlā me kēia kaulahao
• Nā mea hoʻokipa ʻehā ma muli o ka hoʻolālā hoʻololi hoʻohaʻahaʻa 0-IF:
- A hiki i ka 200 MHz o RF loaʻa ka bandwidth i kēlā me kēia kaulahao
• Ke kaulahao manaʻo e pili ana i ka RF sampling ADC:
- A hiki i 600 MHz o RF loaʻa ka bandwidth
• Ka laulā RF: 600 MHz a 6 GHz
• Wideband fractional-N PLL, VCO no TX a me RX LO
• Hoʻolaʻa ʻia integer-N PLL, VCO no nā mea hoʻololi ʻikepili i ka hana ʻana
• Kākoʻo ʻo JESD204B a me JESD204C SerDes:
- 8 SerDes transceivers a hiki i 29.5 Gbps
- 8b/10b a me 64b/66b hoʻopili
- 16-bit, 12-bit, 24-bit a me 32-bit formatting
- ʻO ka subclass 1 ka hoʻonohonoho ʻana i nā hāmeʻa lehulehu
