1800-2000MHZ UHF Band RF Coaxial Isolator
Chii chinonzi isolator?
Chinopatsanura RFmudziyo weferromagnetic passive une mapombi maviri, unoshandiswa kudzivirira zvimwe zvikamu zveRF kuti zvisakuvadzwe nekuratidzira kwakasimba kwechiratidzo. Zvinobvisa ma signal zvinowanikwa murabhoritari uye zvinogona kuparadzanisa michina iri kuyedzwa (DUT) kubva kune zvinonzwa ma signal sources.
Chikumbiro chechigadzirwa
• Kuongororwa kwerabhoritari (bandwidth yepamusoro-soro)
• Kutaurirana nesatellite
• Sisitimu isina waya

Musiyano uripo pakati pe isolator ne circulator
Circulator mudziyo une maport akawanda unotumira mafungu echiitiko achipinda muchiteshi chipi nechipi kuenda kune chimwe zvichienderana negwara rinotsanangurwa ne static bias magnetic field. Chinhu chinonyanya kukosha ndechekutumira simba nenzira imwe chete, iyo inodzora kutumirwa kwemafungu emagetsi nenzira yakatenderera.
Semuenzaniso, mucirculator iri pamufananidzo uri pazasi, chiratidzo chinogona kungobva pachiteshi 1 kuenda kuchiteshi 2, kubva pachiteshi 2 kuenda kuchiteshi 3, uye kubva pachiteshi 3 kuenda kuchiteshi 1, uye dzimwe nzira dzakavharwa (kupatsanurwa kwakanyanya)
Chinopatsanura chinowanzo enderana nechimiro che circulator. Musiyano chete ndewekuti chinopatsanura chinowanzova mudziyo une maport maviri, unobatanidza maport matatu e circulator kune load kana detection circuit inoenderana. Saka, basa rakadaro rinoumbwa: chiratidzo chinogona kungobva pa port 1 kuenda pa port 2, asi hachikwanise kudzokera ku port 1 kubva pa port 2, kureva kuti, kuenderera mberi kwenzira imwe chete kunoitika.
Kana 3-port yakabatana ne detector, dhigirii rekusawirirana kwe terminal device rakamiswa ne 2-port rinogonawo kuonekwa, uye basa rekutarisa mafungu akamira rinogona kuonekwa.
