Mafirita eBand Reject RF Coaxial Comb Interdigital Microstrip Microwave Millimeter Wave Radio Frequency Spiral Yakasungirirwa Stripline
Sefa yeKuramba Bhendi
Bhandi Reject Filter ifirita inoshandiswa mukugadzirisa masaini kudzvinyirira hukuru hwechiratidzo mukati mehuwandu hwakatarwa hwemafrequency uku uchibvumira masaini mune mamwe mafrequency kuti apfuure. Nheyo inoshanda yefirita rebhendi rereject ndeyekuongorora chiratidzo chekupinda mu frequency domain, uye kusarudza kudzvinyirira amplitude yechiratidzo zvichienderana nehuwandu hwemafrequency hwakatarwa, kuitira kuti ruzha ruderedzwe pahuwandu hwakatarwa.
Mafirita ekubvisa mabhendi anokamurwa kuita mafirita ekubvisa mabhendi emumba, mafirita ekubvisa mabhendi epakati pedhijitari, mafirita ekubvisa mabhendi emumativi, mafirita ekubvisa mabhendi emumativi akasungirirwa.
Zvinotevera ndizvo zvinhu zvikuru zvinoitwa nemafirita emhando ye millimeter wave band reject:
1. Kutumirwa kwechiratidzo cheblock mune imwe frequency range: band-stop filter haina transfer function ye zero, asi ine transfer function shoma pane central cutoff frequency. Saka, inogona kuvharira transmission yesignals kuburikidza ne central frequency range yayo.
2.Bvumira mamwe masaini efrequency kuti apfuure: Pamusoro pehuwandu hwemafrequency ari pakati, firita reband-stop rinobvumira masaini emamwe mafrequency ese kuti apfuure. Izvi zvinobvumira mafirita eband-stop kuti ashandiswe kubvisa ruzha, kupindira uye kusangana nezvinodiwa zvemafrequency chaiwo.
3. Kukanganiswa kwemafungu madiki: zvichienzaniswa nedzimwe mhando dzemafirita, mafirita ebhendi-stop ane kukanganiswa kwemafungu madiki. Izvi zvinoreva kuti anogona kuchengetedza zviri nani chimiro uye amplitude yechiratidzo chinopfuura nepafirita.
4. Kugadziriswa kwechiratidzo cheBroadband: Sefa yeband-stop inogona kushandiswa kugadzirisa zviratidzo zvebroadband, nekuti inogona kuchengetedza zvikamu zvakawanda zvefrequency uye inongovhara huwandu hwakati hwefrequency.
5. Mhinduro yechikamu: Mhinduro yechikamu chefirita yebhendi-stop inoenderana nekugadzirwa kwayo uye kushandiswa kwayo, asi kazhinji iri pakati pefirita yepasi-pasi nefirita yepasi-pasi.
Kushandisa mafirita e microstrip band reject:
1. Kugadziriswa kwechiratidzo chemagetsi: Mafirita eRF band reject anogona kushandiswa kusefa mamwe mafrequency ekupindira mukugadzirisa chiratidzo chemagetsi, nokudaro zvichivandudza kunaka kwechiratidzo.
2. Kutaurirana neredhiyo: Mukutaurirana neredhiyo, mafirita eredhiyo anogona kushandiswa kuchenesa mafrequency asina basa mumasaini, nokudaro zvichivandudza kunaka kwekutaurirana.
3. Magetsi emagetsi ane mafrequency akawanda: Mafirita ekumisa mabhendi anogona kushandiswa kugadzirisa mafrequency response mumasekete kuti awane mashandiro anodiwa esekete.
4. Midziyo yekurapa: Mafirita eCoaxial band reject anogona kushandiswa mumidziyo yekurapa, senge electrocardiogram instruments, kuchenesa mafrequency kubva mutsandanyama nezvimwe zvinhu zvinokanganisa zvekunze.
Qualwaveinopa mafirita ekurambwa kwebhendi rema stopband akawanda ari pahuwandu hwema frequency DC-40GHz. Mafirita ekurambwa kwebhendi rema microwave anoshandiswa zvakanyanya mumabasa akawanda.
