Yiziphi Izingxenye Ezifakiwe Ku-Front-end Ye-Radio Frequency

Ezinhlelweni zokuxhumana ezingenantambo, ngokuvamile kunezingxenye ezine: i-antenna, i-radio frequency (RF) front-end, i-RF transceiver, kanye ne-baseband signal processor.

Ngokufika kwesikhathi se-5G, isidingo kanye nenani lama-antenna kanye nama-front-end e-RF kukhuphuke ngokushesha. I-front-end ye-RF iyinto eyisisekelo eguqula amasignali edijithali abe amasignali e-RF angenantambo, futhi futhi iyisici esiyinhloko sezinhlelo zokuxhumana ezingenantambo.

Ngokusebenza kahle, i-RF front-end ingahlukaniswa ibe yi-transmit side (Tx) kanye ne-receive side (Rx).

● Hlunga: Ikhetha amaza athile futhi ihlunge amasignali okuphazamisa

● I-Duplexer/I-Multiplexer: Ihlukanisa izimpawu ezidluliselwe/ezamukelwe

● Isikhulisi Samandla (PA): Sandisa amasignali e-RF ukuze kudluliselwe

● Isikhulisi Somsindo Ophansi (i-LNA): Sikhulisa amasignali atholiwe ngenkathi sinciphisa ukwethulwa komsindo

● Iswishi ye-RF: Ilawula ukuvulwa/ukuvalwa kwesekethe ukuze kube lula ukushintsha isignali

● Ishuna: Ukufanisa i-impedance ye-antenna

● Ezinye izingxenye ze-RF front-end

I-Envelope Tracker (ET) isetshenziselwa ukuthuthukisa ukusebenza kahle kwe-power amplifier yezibonakaliso ezinezilinganiso zamandla eziphezulu kakhulu kuya kwesilinganiso ngokunika amandla okukhipha amandla aguquguqukayo akhulisiwe.

Uma kuqhathaniswa namasu okulandelela amandla ajwayelekile, ukulandelela imvilophu kuvumela i-voltage yokunikezwa kwamandla ye-amplifier ukuthi ilandele imvilophu yesiginali yokufaka, okuthuthukisa ukusebenza kahle kwamandla e-RF power amplifier.

I-RF Receiver eguqula amasignali e-RF atholakele nge-antenna ngokusebenzisa izingxenye ezifana nezihlungi, ama-LNA, kanye nabaguquli be-analog-to-digital (ama-ADC) ukuze baguqule futhi banciphise isignali, ekugcineni bakhe isignali ye-baseband njengokukhipha.

I-Concept Microwave ingumkhiqizi ochwepheshe wezingxenye ze-5G RF eShayina, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/band stop, i-duplexer, i-Power divider kanye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokwezidingo zakho.
