Tsanangura muchidimbu maparamita ekushanda kweRF isolators

Mumasystem eRF, basa guru reZvidziviriri zveRFndeyekupa kana kusimudzira kugona kwekuparadzanisa nzira dzakasiyana dzemasaini. Iro circulator rakavandudzwa rinogumiswa nekubatanidza impedance pane imwe yenzvimbo dzaro. Inowanzo shandiswa muma radar systems kudzivirira maseketi anonzwa padivi rekugamuchira kudzivirira kukanganiswa kubva kumasaini anotumirwa ane simba guru, nokudaro zvichiita kuti zviratidzo zvinotumirwa nezvinogamuchirwa zvisaparadzwe zvinobudirira. Chinyorwa chino chichakutungamira kuti unzwisise ma core performance parameters eZvidziviriri zveRF.

一. Tsanangudzo
Zvidziviriri zveRFchaizvoizvo imhando yakakosha yeMacirculator eRF, umo chiteshi chimwe (kazhinji mugumo wenzira yekudzokera shure kwecheni yechiratidzo) chinogumiswa nemutoro unoenderana kuti uwane kutapurirana kwemasaini nenzira imwe chete. Zvinongobvumira masaini kuti apfuure nenzira yakatarwa uku achidzvinyirira kuratidzwa, ruzha kana zviratidzo zvekupindira kubva kune imwe nzira yekudzokera shure, nokudaro zvichiita kuti pave nekuparadzaniswa kwakanaka kwekubatanidza kwakapfuura.

Zvidziviriri zveRF or macirculatorkazhinji zvishandiso zveferrite zvinongotungamira mafungu emagetsi kubva kumagumo ekupinda munzira chaiyo kuburikidza nechimiro chesimba remagineti uye kubuda pachiteshi chiri pedyo.

Zvichienzaniswa nezvinodzivirira zvakagadziriswa kubva kune zvechinyakareMacirculator eRF, zvishandiso zvakagadzirirwa zvinangwa zvekuzviparadzanisa zvinowanzova zvidiki uye zviri nyore kubatanidza. Kushanda kwayo kwekuparadzanisa kunokanganiswa zvakananga nehunhu hwekufananidza terminal.

Zvimwe. Magadzirirwo ekushanda
Zviratidzo zvikuru zvekushanda kweZvidziviriri zveRFzvinosanganisira:

Range yefrequency (Hz)

Kusapindirana (Ω)

Kurasikirwa kwekuisa (dB)

Kuzviparadzanisa (dB)

Chiyero chemagetsi akamira (VSWR)

Kugona kubata simba rekufambisa mberi (wave inoenderera mberi kana kuti peak)

Kugona kubata simba rekudzosera kumashure (wave inoenderera mberi kana kuti peak)

Rudzi rwekubatanidza

Pakati pazvo, kupatsanurana ndeimwe yematanho akakosha, anoratidza mwero wekubatana pakati penzira dzeRF muma decibel (dB). Kana kukosha kwacho kwakakwira, kubatana pakati pezviratidzo kudiki uye mhedzisiro yekupatsanurana iri nani. Sezvo kupatsanurana kwemagetsi kuchiwanikwa munzvimbo dzese dzinofambisa magetsi, zvakakosha kuchengetedza kupatsanurana kwakanyanya pakati penzira dziri muhurongwa hwekutaurirana hwakanyatsojeka kana hwekuona.

Pamusoro pezvo, zvichienderana nezvinodiwa zvakasiyana zvekushandisa,zvinoparadzanisainofanirawo kunge iine simba rakakodzera rekubata magetsi, VSWR yakaderera, chimiro chekubatanidza chakavimbika kwazvo, saizi yakakodzera, uye tembiricha yekushanda inochinjika, izvo zvinogona kukanganisa mashandiro azvo mumamiriro ezvinhu chaiwo. Simba rakawanda reisolator rinogonawo kuganhurirwa nehunhu hwemutoro wakagumiswa.
