Rondedzera muchidimbu maitiro ekuita kweRF isolators

MuRF masisitimu, iro basa guru reRF isolatorsKupa kana kuwedzera kugona kwekuzviparadzanisa nevamwe kune nzira dzakasiyana dzechiratidzo. Iyo inotenderera inotenderera inomiswa nekufananidza impedance pane imwe yemachiteshi ayo. Inowanzo shandiswa mumasisitimu eradar kuchengetedza maseketi anonzwisa tsitsi pamagumo ekugamuchira kuti adzivise kukanganiswa kubva kune yakakwirira-simba anotapurirwa masaini, nekudaro kuwana kunoshanda kuparadzaniswa kweanotapurirana uye anogamuchirwa masaini. Ichi chinyorwa chinokutora iwe kuti unzwisise iyo core performance parameters yeRF isolators.

一. Tsanangudzo
RF isolatorsvane chimiro chakakosha cheRF circulators, mune imwe chiteshi (kazhinji nzira yekudzokera kumashure kwecheni yechiratidzo) inomiswa nemutoro unofananidzwa kuti uwane unidirectional kutapurirana kwezviratidzo. Inongobvumira masaini kuti apfuure munzira yakafanotemerwa uku achidzvanya maratidziro, ruzha kana masaini ekuvhiringidza kubva kune reverse direction, nekudaro kuwana kunoshanda kuparadzaniswa kweiyo yapfuura link.

RF isolators or circulatorszvinowanzoita zvigadziriso zveferrite zvinotungamira mafungu emagetsi kubva kumagumo ekupinza mune yakananga nzira kuburikidza neiyo chaiyo magineti yekumisikidza uye inobuda pachiteshi chiri padyo.

Kuenzaniswa nemaisolator akagadziridzwa kubva kune akajairwaRF circulators, zvishandiso zvakagadzirirwa zvakanangana nezvinangwa zvekuzviparadzanisa zvinowanzova compact uye nyore kubatanidza. Kuita kwayo kwekuzviparadzanisa kunokanganiswa zvakananga nemhando yeterminal matching.

High frequency standard isolator, Isolation (12-14dB), 18 kusvika 40GHz

二. Performance parameters
Izvo zvakakosha zvekushanda zviratidzo zveRF isolatorszvinosanganisira:

Frequency range (Hz)

Impedance (Ω)

Kurasikirwa kwekupinza (dB)

Kuzviparadzanisa nevamwe (dB)

Voltage standing wave ratio (VSWR)

Pamberi simba rekubata kugona (inoenderera wave kana peak)

Reverse simba kubata kugona (inoenderera mberi wave kana peak)

Connector type

Pakati pavo, kuzviparadzanisa ndeimwe yeakanyanya kuomesesa paramita, iyo inoratidza dhigirii rekubatanidza pakati peRF nzira mumadecibel (dB). Iyo yakakwirira kukosha, iyo idiki yekubatanidza pakati pezviratidzo uye zviri nani kuita kwekuzviparadzanisa nevamwe. Sezvo electromagnetic coupling yakatekeshera munzira dzese dzekufambisa, zvinonyanya kukosha kuchengetedza yakasarudzika pakati pemakwara mune yakakwirira-chaiyo yekutaurirana kana yekunzwa masisitimu.

Mukuwedzera, maererano nezvinodiwa zvakasiyana zvekushandisa,isolatorsinofanirawo kuve neyakakodzera simba rekubata simba, yakaderera VSWR, yakakwirira-yakavimbika yekubatanidza chimiro, saizi yakakodzera, uye inochinjika inoshanda tembiricha renji, izvo zvinogona kukanganisa kuita kwavo mumamiriro chaiwo. Iyo yakanyanya simba indekisi yeiyo isolator inogonawo kuganhurwa nemaitiro emutoro wakagumiswa.
