Radio frequency (RF) & microwave mafirita anotsanangurwa semhando yemagetsi sefa, akagadzirirwa kushanda pamasaini mu megahertz kune gigahertz frequency renji (yepakati frequency kusvika yakanyanyisa frequency).Iyi frequency renji yesefa ndiyo iyo inoshandiswa nenhepfenyuro zhinji, terevhizheni, kutaurirana pasina waya (nharembozha, Wi-Fi, nezvimwewo), uye nekudaro mazhinji eRF uye microwave zvishandiso zvinosanganisira imwe mhando yekusefa pamasaini anofambiswa kana anogamuchirwa.Mafirita akadaro anowanzo shandiswa sezvivharo zvekuvaka zve duplexers uye diplexers kusanganisa kana kupatsanura akawanda frequency mabhendi.
Mabasa:
1. Rf sefa inogona kuderedza frequency band kukanganisa uye kuvandudza kushanda kwe-co-inowanikwa michina.
2. Sefa yeRF inobvumira chete frequency uye chiteshi chiri kufambiswa kana kugamuchirwa kuti chipfuure uye chinoderedza kukanganiswa kwechiratidzo kunze kwechiteshi.
Pahwaro hwebasa rayo, zvinoenderana neiyo frequency renji yechiratidzo chekushanda kurongedza RF mafirita, iwo akakamurwa muzvikamu zvina, kureva, low pass filter (LPF), high pass filter (HPF), band pass filter ( BPF) uye bhendi stop sefa (BSF).
1. Low-pass sefa : Inoreva sefa iyo yakaderera frequency chiratidzo inogona kupfuura asi yakakwirira frequency chiratidzo haigone kupfuura;
2. High-pass filter: Izvo zvinopesana, kureva kuti, zviratidzo zvepamusoro-soro zvinogona kupfuura uye zviratidzo zvishoma-zvishoma hazvigoni kupfuura;
3. Band-pass sefa: Inoreva kuwanda mune imwe frequency renji yemasaini anogona kupfuura, RF sefa uye kunze kweiyo frequency renji yemasaini haigone kupfuura;
4. Band-stop filter: Kuita kwebhandi-stop sefa kunopesana, kureva kuti, zviratidzo muchikwata chebhendi zvakavharwa, asi zviratidzo kunze kweiyi frequency range inobvumirwa kupfuura;
RF mafirita anogona kuiswa muSAW sefa, BAW sefa, LC sefa, cavity sefa, ceramic sefa zvinoenderana nechimiro kana zvinhu zvawo zvakare.
Jingxin, senyanzvimugadziri weRF passive components, inogona kupa ari pamusoro peRF mafirita ekutarisa, ayo anga achigadzira anopfuura makore gumi kugadzira uye kugadzira RF mafirita emhando dzakasiyana dzekushandisa, senge DAS mhinduro, BAD system, kutaurirana kwemauto, uye kuwana kurumbidzwa kwakanyanya kwekubudirira kubva vatengi.Iyo tsika dhizaini mafirita anogona kuitwa naJingxin zvinoenderana netsanangudzo zvakare, yakawanda mubvunzo inogamuchirwa.
