Wireless kutaurirana masisitimu anowanzo sanganisira zvikamu zvina: antenna, radio frequency kumberi-kuguma, radio frequency transceiver module, uye baseband chiratidzo processor.
Nekuuya kweiyo 5G era, kudiwa uye kukosha kweantennas uye redhiyo frequency kumberi-kuguma kuri kusimuka nekukurumidza. Iyo redhiyo frequency kumberi-yekupedzisira ndicho chinhu chakakosha chinoshandura masaini edhijitari kuita isina waya redhiyo frequency masaini uye zvakare ndicho chinhu chakakosha cheiyo isina waya yekutaurirana system.
Zvinoenderana nebasa racho, redhiyo frequency kumberi-kumagumo inogona kukamurwa kuita yekuparadzira magumo Tx uye yekugamuchira magumo Rx.
Zvinoenderana neakasiyana maturusi, iyo RF yekumberi-yekupedzisira inogona kukamurwa kuita magetsi amplifiers (RF chiratidzo chekusimudzira pamagumo ekutumira),filters (signal kusefa pane transmitter uye inogamuchira inopera),low-noise amplifiers (chiratidzo chekusimudzira pamagumo ekugamuchira, kuderedza ruzha), switch (kuchinja pakati pezviteshi zvakasiyana),Duplexer(kusarudzwa kwechiratidzo, kufananidzwa kwesefa), tuner (antenna chiratidzo chiteshi impedance inoenderana), nezvimwe.
Sefa: gedhi chairo frequency uye masaini ekukanganisa masaini
The sefandiyo inonyanya kukosha discrete mudziyo muRF kumberi-kuguma. Iyo inobvumira zvakati wandei zvikamu muchiratidzo kuti zvipfuure uye zvinoremedza zvakanyanya zvimwe zvikamu zve frequency, nekudaro zvichivandudza chiratidzo chekudzivirira-kupindira uye chiratidzo-ku-ruzha chiyero.
Diplexer/Multiplexer: Kuparadzaniswa kwekutumira / kugamuchira zviratidzo
The duplexer, inozivikanwawo seantenna duplexer, ine maseti maviri ebhendi-stop mafirita ane ma frequency akasiyana.
The duplexerinoshandisa frequency division function yehigh-pass, yakaderera-pass kana bhendi-pass sefa kubvumira antenna imwechete kana tambo yekutumira kushandisa nzira mbiri dzechiratidzo, zvichigonesa iyo antenna imwe chete kugamuchira uye kutumira masaini emhando mbiri dzakasiyana.
Low noise amplifier(LNA): inokudza chiratidzo chinogamuchirwa uye inoderedza kuiswa kweruzha
The low-noise amplifieriri amplifier ine ruzha rudiki. Basa rayo nderekukwidziridza isina simba redhiyo frequency siginecha inogamuchirwa neantenna uye kuderedza kuunzwa kweruzha. Iyo LNA inogona kunyatso kuvandudza kugashira kwekunzwa kweanogamuchira, nekudaro ichiwedzera kureba kwekufambisa kweiyo transceiver.
Asa inyanzvi & inovandudza mugadziri weRF & Microwave zvikamu, CHengdu Jingxin Microwave Technology Co., Ltd inyanzvi mukugadzira nekugadzira zvakasiyana-siyana zvezvakajairwa uye zvetsika-dhizaini zvikamu zvine inotungamira kuita kubva kuDC kusvika ku110GHz.
