Macirculator nema isolators: zvishandiso zvepakati muRF uye ma microwave circuits

MuRF uye microwave circuits, macirculator nema isolators zvishandiso zviviri zvakakosha zvinoshandiswa zvakanyanya nekuda kwebasa ravo rakasiyana uye mashandisirwo aro. Kunzwisisa hunhu hwavo, mashandiro avo uye mamiriro ekushandiswa kwavo kuchabatsira mainjiniya kusarudza mhinduro dzakakodzera mumagadzirirwo chaiwo, nokudaro zvichivandudza mashandiro esystem uye kuvimbika kwayo.

1. Circulator: Mutungamiriri wezviratidzo

1. Chii chinonzi circulator?
Circulator chishandiso chisingadzokorore chinowanzo shandisa zvinhu zveferrite uye simba rekunze remagineti kuti zvisvike pakutumirwa kwemashoko nenzira imwe chete. Kazhinji kacho chine mapoinzi matatu, uye zviratidzo zvinogona kungotumirwa pakati pemapoinzi nenzira yakatarwa. Semuenzaniso, kubva pachiteshi 1 kuenda kuchiteshi 2, kubva pachiteshi 2 kuenda kuchiteshi 3, uye kubva pachiteshi 3 kudzokera kuchiteshi 1.
2. Mabasa makuru ecirculator
Kugoverwa kwezviratidzo uye kubatanidzwa: kugovera zviratidzo zvekupinda kune maports akasiyana ekubuda munzira yakatarwa, kana kubatanidza zviratidzo kubva kumaports akawanda kuenda kuport imwe chete.
Kutumira nekugamuchira kupatsanurwa: kunoshandiswa seduplexer kuti kusvike pakupatsanurwa kwekutumira nekugamuchira masaini muantenna imwe chete.
3. Hunhu hwemacirculator
Kusapindirana: masaini anogona kungotumirwa nenzira imwe chete, kudzivirira kupindirana kwemashure.
Kurasikirwa kwakaderera kwekupinza: kurasikirwa kwesimba shoma panguva yekutumira masaini, kunyanya zvakakodzera kushandiswa kwema frequency akawanda.
Rutsigiro rweWideband: runogona kufukidza huwandu hwakakura hwemafrequency kubva kuMHz kusvika kuGHz.
4. Mashandisirwo akajairika emacirculator
Sisitimu yeradar: inoparadzanisa chinotumira kubva kune chinogamuchira kuti zviratidzo zvekutumira zvine simba guru zvisakuvadze mudziyo unogamuchira.
Sisitimu yekutaurirana: inoshandiswa pakugovera masaini uye kuchinja ma "multi-antenna arrays".
Sisitimu yeAntenna: inotsigira kuparadzaniswa kwemasaini anotumirwa uye anogamuchirwa kuti ivandudze kugadzikana kwesisitimu.

II. Isolator: chipingamupinyi chekudzivirira chiratidzo

1. Chii chinonzi isolator?
Zvidziviriri (isolators) imhando yakasarudzika yemacirculator, anowanzova nemaports maviri chete. Basa rayo guru nderekudzivisa kuratidzwa kwechiratidzo uye kudzokera shure, zvichidzivirira michina inonzwa kubva pakukanganiswa.
2. Mabasa makuru evanobvisa zvinhu zvinokuvadza
Kupatsanurwa kwezviratidzo: kudzivirira zviratidzo zvinoratidzwa kuti zvisadzokere kumashure kumidziyo yekumberi (yakadai sematransmitter kana ma amplifiers emagetsi) kudzivirira kupisa zvakanyanya kana kudzikira kwekushanda kwemidziyo.
Dziviriro yesystem: mumacircuits akaomarara, zvinoparadzanisa zvinogona kudzivirira kupindirana pakati pemamodule ari pedyo uye kuvandudza kuvimbika kwesystem.
3. Hunhu hwezvinhu zvinoparadzanisa
Kutumirwa kwemagetsi nenzira imwe chete: chiratidzo chinogona kungotumirwa kubva kumagumo ekupinda kuenda kumagumo ekubudisa, uye chiratidzo chekudzokera shure chinodzvinyirirwa kana kunyudzwa.
Kuparadzaniswa kwakanyanya: kunopa simba guru rekudzvanya zviratidzo zvinoratidzwa, kazhinji kusvika ku20dB kana kupfuura.
Kurasikirwa kwakaderera kwekupinza: kunoita kuti kurasikirwa kwesimba panguva yekutumirwa kwechiratidzo kwakaderera sezvinobvira.
4. Mashandisirwo akajairika ezvitsaura
Dziviriro yeRF amplifier: kudzivirira masaini anoonekwa kuti asakonzere kusashanda zvakanaka kana kutokuvadza amplifier.
Sisitimu yekutaurirana isina waya: bvisa RF module musystem yeantenna yechiteshi chepasi.
Midziyo yekuedza: bvisa zviratidzo zvinoratidzwa muchishandiso chekuyera kuti uvandudze kururama kwekuyedza.

III. Ungasarudza sei mudziyo wakakodzera?

Pakugadzira maRF kana ma microwave circuits, sarudzo ye circulator kana isolator inofanira kunge yakavakirwa pane zvinodiwa zvekushandisa:
Kana uchida kugovera kana kubatanidza masaini pakati pemaports akawanda, macirculator ndiwo anonyanya kufarirwa.
Kana chinangwa chikuru chiri chekudzivirira mudziyo kana kuderedza kukanganiswa kubva kuzviratidzo zvinoratidzwa, zvinobvisa ruzha (isolators) isarudzo iri nani.
Pamusoro pezvo, huwandu hwema frequency, kurasikirwa kwekuisa, kupatsanurwa uye saizi zvinodiwa zvemudziyo zvinofanirwa kutariswa zvizere kuti zvive nechokwadi chekuti zviratidzo zvekushanda kwesystem chaiyo zvinosangana.

IV. Maitiro Ekuvandudza Ramangwana

Nekuvandudzwa kwetekinoroji yekutaurirana isina waya, kudiwa kweminiaturization uye kushanda kwepamusoro kweRF uye microwave zvishandiso kuri kuramba kuchiwedzera. Macirculator nema isolators ari kukurawo zvishoma nezvishoma munzira dzinotevera:
Rutsigiro rwema frequency akakwira: rutsigiro rwema millimeter wave bands (senge 5G uye millimeter wave radar).
Dhizaini yakabatana: yakabatana nezvimwe zvishandiso zveRF (zvakaita semafirita uye zvinoparadzanisa simba) kuti zvivandudze mashandiro esystem.
Mutengo wakaderera uye miniaturization: shandisa zvinhu zvitsva uye maitiro ekugadzira kuderedza mitengo uye kugadzirisa zvinodiwa nemidziyo yemagetsi.
