Zomwe Zimaphatikizidwa mu Radio Frequency Front-end

Radio Frequency Front-end1

M'makina olumikizirana opanda zingwe, nthawi zambiri pamakhala zigawo zinayi: mlongoti, ma frequency radio (RF) kutsogolo, RF transceiver, ndi baseband sign processor.

Kubwera kwa nthawi ya 5G, kufunikira ndi kufunika kwa tinyanga zonse ndi ma RF kutsogolo kwakwera kwambiri.Kumapeto kwa RF ndiye gawo lofunikira lomwe limasintha ma siginecha a digito kukhala ma siginecha a RF opanda zingwe, komanso ndi gawo lofunikira pamakina olumikizirana opanda zingwe.

Radio Frequency Front-end2

Mwachidziwitso, kumapeto kwa RF kumatha kugawidwa mbali yotumizira (Tx) ndikulandila mbali (Rx).

● Zosefera: Zimasankha ma frequency enieni ndikusefa zizindikiro zosokoneza

● Duplexer/Multiplexer: Amapatula zizindikiro zopatsirana/zolandira

● Power Amplifier (PA): Imakulitsa zizindikiro za RF kuti zitumizidwe

● Low Noise Amplifier (LNA): Imakulitsa zidziwitso zolandilidwa ndikuchepetsa kuyambitsa phokoso

● Kusintha kwa RF: Kuwongolera kuzungulira / kuzimitsa kuti ziwongolere kusintha kwa siginecha

● Chochunira: Kulepheretsa kufanana kwa mlongoti

● Zida zina za RF kutsogolo

Envelope Tracker (ET) imagwiritsidwa ntchito kupititsa patsogolo mphamvu zokulitsa mphamvu zamasiginecha okhala ndi nsonga-mpaka-avareji yamagetsi pothandizira kutulutsa mphamvu zosinthika.

Poyerekeza ndi njira zotsatirira mphamvu, kutsatira ma envelopu kumalola mphamvu yamagetsi ya amplifier kuti itsatire envelopu ya siginecha yolowera, ndikuwongolera mphamvu ya RF amplifier mphamvu.

Otembenuza a RF Receiver adalandira ma siginecha a RF kudzera mu mlongoti kudzera m'zigawo monga zosefera, LNAs, ndi zosinthira za analog-to-digital (ADCs) kuti zitsitse ndikutsitsa chizindikirocho, pomaliza kupanga chikwangwani cha baseband ngati chotuluka.

Concept Microwave ndi katswiri wopanga zida za 5G RF ku China, kuphatikiza fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop fyuluta, duplexer, Power divider ndi directional coupler.Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
