Mune masisitimu emazuva ano ekutaurirana, iyo Radio Frequency (RF) yekumberi-yekupedzisira inoita basa rakakosha mukugonesa kutaurirana pasina waya. Yakamisikidzwa pakati peantenna nedigital baseband, iyo RF yekumberi-yekupedzisira ine basa rekugadzirisa masaini anouya uye anobuda, zvichiita kuti ive chinhu chakakosha mumidziyo kubva kumafoni kusvika kumasetiraiti.
Chii chinonzi RF Front-End?
Iyo RF yekumberi-yekupedzisira ine zvikamu zvakasiyana zvinobata chiratidzo chekugamuchira uye kutapurirana. Zvinhu zvakakosha zvinosanganisira magetsi amplifiers (PA), low-noise amplifiers (LNA), mafirita, uye switch. Izvi zvikamu zvinoshanda pamwe chete kuti ive nechokwadi chekuti masaini anofambiswa nesimba rinodiwa uye kujeka, uku ichideredza kupindira uye ruzha.
Kazhinji, zvese zviri pakati peantenna neRF transceiver zvinodaidzwa kuti RF kumberi-kuguma, kuve nechokwadi chekufambiswa kwewaya isina waya.
2) Chikamu uye Basa reRF Front-End
Iyo RF yekumberi-yekupedzisira inogona kuiswa mumhando mbiri huru zvichienderana neiyo fomu: discrete zvikamu uye RF module. Discrete zvikamu zvinoiswazve kupatsanurwa zvichienderana nebasa razvo, nepo RF mamodule akakamurwa kuita akaderera, epakati, uye akakwira ekubatanidza mazinga. Pamusoro pezvo, zvichienderana neiyo nzira yekufambisa yechiratidzo, iyo RF yekumberi-yekupedzisira yakakamurwa kuita nzira dzekufambisa uye dzekugamuchira.
Kubva muchikamu chinoshanda chemidziyo yakasarudzika, zvikamu zvakakosha zveRF kumberi-kuguma zvinosanganisira zvakakamurwa kuita simba amplifier (PA), duplexer (Duplexer uye Diplexer), radio frequency switch (Switch), sefa (Filter) uye yakaderera ruzha amplifier (LNA), nezvimwewo,. Izvi zvikamu, pamwe chete nebaseband chip, zvinogadzira yakazara RF system.
Power Amplifiers (PA): Simbisa chiratidzo chiri kufambiswa.
Duplexers: Kusiyanisa kutapurirana uye masaini masaini, achibvumira zvishandiso kugovera imwechete antenna zvinobudirira.
Radio frequency switch (Chinja): Gonesa kuchinja pakati pekutapurirana uye kugamuchira kana pakati pemabhendi akasiyana.
Mafirita: Sefa ma frequency asingadiwe uye chengeta chiratidzo chaunoda.
Low-Noise Amplifiers (LNA): Kurisa masaini asina simba munzira yekugamuchira.
RF modules, zvichienderana nehuwandu hwavo hwekubatanidza, kubva kune yakaderera-yekubatanidza modules (yakadai seASM, FEM) kusvika pakati-yekubatanidza modules (seDiv FEM, FEMID, PAiD), uye yakakwirira-yekubatanidza modules (yakadai sePAMiD, LNA Div FEM). ) Mhando yega yega yemodule yakagadzirirwa kusangana nezvinodiwa zvakasiyana zvekushandisa.
Kukosha muCommunication Systems
Iyo RF yekumberi-yekupedzisira ndiyo kiyi inogonesa yekushanda isina waya kutaurirana. Iyo inotaridza kuita kwese kwese system maererano nesimba rechiratidzo, mhando, uye bandwidth. Mumaserura network, semuenzaniso, iyo RF yekumberi-yekupedzisira inovimbisa kutaurirana kwakajeka pakati pechishandiso uye base chiteshi, ichipesvedzera zvakananga mhando yekufona, kumhanya kwedata, uye yekuvhara.
Tsika RF Front-End Solutions
Apex inyanzvi mukugadzira tsika dzeRF dzemberi-yekupedzisira zvikamu, ichipa mhinduro dzakagadzirirwa kusangana nezvinodiwa zvemhando dzakasiyana dzekutaurirana masisitimu. Yedu yemhando yeRF yekumberi-yekupedzisira zvigadzirwa inogonesa kuita kwakakwenenzverwa kwekushandisa munharembozha, aerospace, kudzivirira, nezvimwe.
Mhedziso
Iyo RF yekumberi-yekupedzisira chikamu chakakosha chechero nzira yekutaurirana, kuve nechokwadi chekufambisa kwemasaini uye kugamuchira uku uchideredza kupindira. Nekufambira mberi mune tekinoroji uye kukura kwekuda kwekuita kwepamusoro, kukosha kwepamusoro-mhando yeRF yekumberi-yekupedzisira mhinduro kuri kuramba kuchikwira, zvichiita kuti ive chinhu chakakosha mumatambo emazuva ano asina waya.
