Hauv cov kab ke sib txuas lus wireless, feem ntau muaj plaub yam khoom: lub antenna, radio frequency (RF) front-end, RF transceiver, thiab baseband signal processor.
Nrog rau kev tshwm sim ntawm lub caij nyoog 5G, qhov kev thov thiab tus nqi rau ob qho tib si antennas thiab RF pem hauv ntej tau nce sai. RF pem hauv ntej yog qhov tseem ceeb uas hloov cov teeb liab digital mus rau hauv cov teeb liab wireless RF, thiab tseem yog lub hauv paus ntawm cov kab ke sib txuas lus wireless.
Ua haujlwm tau zoo, RF pem hauv ntej tuaj yeem faib ua sab xa (Tx) thiab sab txais (Rx).
● Lim: Xaiv cov zaus tshwj xeeb thiab lim tawm cov teeb liab cuam tshuam
● Duplexer/Multiplexer: Cais cov teeb liab xa/tau txais
● Lub Tshuab Nqus Fais Fab (PA): Ua kom cov teeb liab RF nrov dua rau kev xa xov
● Lub Tshuab Ua Kom Suab Nrov Tsawg (LNA): Ua kom cov teeb liab tau txais nrov dua thaum txo qhov suab nrov nkag los
● RF Hloov: Tswj lub voj voog qhib/kaw kom yooj yim rau kev hloov pauv teeb liab
● Tuner: Impedance phim rau lub antenna
● Lwm yam khoom siv RF pem hauv ntej
Ib lub Envelope Tracker (ET) yog siv los txhim kho kev ua haujlwm ntawm lub zog amplifier rau cov teeb liab uas muaj qhov sib piv ntawm lub zog siab tshaj plaws mus rau qhov nruab nrab los ntawm kev ua kom muaj zog hloov kho tau.
Piv rau cov txheej txheem ntsuas hluav taws xob nruab nrab, kev ntsuas lub hnab ntawv tso cai rau lub zog fais fab ntawm lub amplifier kom ua raws li lub hnab ntawv ntawm lub teeb liab nkag, txhim kho RF lub zog amplifier siv hluav taws xob zoo.
Ib qho RF Receiver hloov cov teeb liab RF tau txais los ntawm lub kav hlau txais xov los ntawm cov khoom xws li cov lim dej, LNAs, thiab cov hloov pauv analog-rau-digital (ADCs) kom downconvert thiab demodulate lub teeb liab, thaum kawg tsim cov teeb liab baseband ua cov zis.
Concept Microwave yog ib lub tuam txhab tsim khoom ntawm 5G RF Cheebtsam hauv Suav teb, suav nrog RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider thiab directional coupler. Tag nrho lawv tuaj yeem hloov kho raws li koj cov kev xav tau.
