Yiziphi Izingxenye Ezifakwe Ku-Frequency Front-end yomsakazo

Ezinhlelweni zokuxhumana ezingenazintambo, ngokuvamile kunezingxenye ezine: uthi, imvamisa yomsakazo (RF) front-end, RF transceiver, kanye ne-baseband signal processor.

Ngokufika kwenkathi ye-5G, isidingo nenani lawo womabili ama-antenna kanye ne-RF front-ends kukhuphuke ngokushesha.I-RF front-end iyingxenye ebalulekile eguqula amasignali edijithali abe amasignali e-RF angenawaya, futhi iyingxenye eyinhloko yezinhlelo zokuxhumana ezingenazintambo.

Ngokusebenza, i-RF front-end ingahlukaniswa ibe uhlangothi lokudlulisa (Tx) bese luthola uhlangothi (Rx).

● Isihlungi: Ikhetha amaza athile futhi ihlunge amasignali okuphazamisa

● I-Duplexer/Multiplexer: Ihlukanisa amasignali adlulisiwe/amukelwe

● Isikhulisi Samandla (PA): Sikhulisa amasignali e-RF ukuze adluliselwe

● Isihlelamsindo esiphansi (LNA): Sikhulisa amasiginali atholiwe ngenkathi sinciphisa isingeniso somsindo

● Ukushintsha kwe-RF: Ilawula ukuvuleka/ukuvala isekethe ukuze kube lula ukushintsha isignali

● Ishuna: Ukuphazamiseka kokufanisa uthi

● Ezinye izingxenye ze-RF front-end

I-Envelope Tracker (ET) isetshenziselwa ukuthuthukisa ukusebenza kahle kwesikhulisi samandla kumasiginali anezilinganiso zamandla aphezulu ukusuka phezulu ukuya kokumaphakathi ngokunika amandla okukhiphayo okukhuliswe amandla okuguquguqukayo.

Uma kuqhathaniswa nezindlela zokulandelela amandla ezimaphakathi, ukulandelela imvilophu kuvumela amandla kagesi wesikhulisi samandla ukuthi alandele imvilophu yesiginali yokufaka, ukuthuthukisa ukusebenza kahle kwamandla kwesikhulisi samandla e-RF.

I-RF Receiver converts ithole amasiginali e-RF nge-antenna ngokusebenzisa izakhi ezifana nezihlungi, ama-LNA, neziguquli ze-analog-to-digital (ADCs) ukuze iguqule futhi yehlise isignali, ekugcineni yenze isignali ye-baseband njengokuphumayo.

I-Concept Microwave ingumkhiqizi ochwepheshile wezingxenye ze-5G RF e-China, okuhlanganisa isihlungi se-RF lowpass, isihlungi se-highpass, isihlungi se-bandpass, isihlungi se-notch/i-band stop filter, i-duplexer, isihlukanisi samandla kanye ne-coupler eqondisayo.Zonke zingenziwa ngezifiso ngokuya ngezidingo zakho.
