M'mabwalo a RF ndi ma microwave, zozungulira ndi zodzipatula ndi zida ziwiri zofunika zomwe zimagwiritsidwa ntchito kwambiri chifukwa cha ntchito zawo zapadera komanso kugwiritsa ntchito kwawo. Kumvetsetsa mawonekedwe awo, magwiridwe antchito ndi mawonekedwe ogwiritsira ntchito kumathandizira mainjiniya kusankha mayankho oyenera pamapangidwe enieni, potero kuwongolera magwiridwe antchito ndi kudalirika.
1. Circulator: Woyang'anira mayendedwe azizindikiro
1. Kodi circulator ndi chiyani?
Wozungulira ndi chipangizo chosasinthana chomwe nthawi zambiri chimagwiritsa ntchito zida za ferrite ndi gawo lakunja la maginito kuti tikwaniritse kufalikira kwa ma siginecha unidirectional. Nthawi zambiri imakhala ndi madoko atatu, ndipo ma siginecha amatha kutumizidwa pakati pa madoko munjira yokhazikika. Mwachitsanzo, kuchokera ku doko 1 kupita ku doko 2, kuchokera ku doko 2 kupita ku doko 3, ndi kuchokera ku doko 3 kubwerera ku doko 1.
2. Ntchito zazikulu za circulator
Kugawa ndi kuphatikiza ma siginecha: gawani ma siginecha olowera kumadoko osiyanasiyana otuluka munjira yokhazikika, kapena phatikizani ma siginolo kuchokera kumadoko angapo kupita kudoko limodzi.
Tumizani ndikulandila kudzipatula: kugwiritsidwa ntchito ngati duplexer kukwaniritsa kudzipatula ndikulandila ma sign mu mlongoti umodzi.
3. Makhalidwe a ozungulira
Kusabwerezabwereza: Zizindikiro zimatha kutumizidwa mbali imodzi, kupewa kusokoneza m'mbuyo.
Kutayika kwapang'ono: kutayika kwa mphamvu pang'ono panthawi yotumizira ma siginecha, makamaka oyenera kugwiritsa ntchito pafupipafupi kwambiri.
Thandizo la Wideband: imatha kuphimba ma frequency osiyanasiyana kuchokera ku MHz mpaka GHz.
4. Ntchito yofananira ndi ma circulator
Dongosolo la radar: imalekanitsa chotumizira kuchokera kwa wolandila kuti aletse ma siginecha amphamvu kwambiri kuti asawononge chipangizo cholandirira.
Njira yolumikizirana: imagwiritsidwa ntchito pogawa ma siginecha ndikusintha masinthidwe amitundu yambiri.
Dongosolo la antenna: limathandizira kudzipatula kwa ma siginecha omwe amafalitsidwa ndikulandilidwa kuti apititse patsogolo bata.
II. Isolator: chotchinga chitetezo chotchinga
1. Kodi wodzipatula ndi chiyani?
Ma Isolators ndi mawonekedwe apadera ozungulira, nthawi zambiri amakhala ndi madoko awiri okha. Ntchito yake yayikulu ndikupondereza kuwonetsa kwazizindikiro ndi kubwerera m'mbuyo, kuteteza zida zodziwikiratu kuti zisasokonezedwe.
2. Ntchito zazikulu za odzipatula
Kudzipatula kwa ma Signal: kupewa ma siginecha owonetseredwa kuti asabwerere ku zida zakutsogolo (monga ma transmitters kapena ma amplifiers) kuti mupewe kutenthedwa kapena kuwonongeka kwa zida.
Chitetezo chadongosolo: m'mabwalo ovuta, zodzipatula zimatha kupewa kusokonezana pakati pa ma module oyandikana ndikuwongolera kudalirika kwadongosolo.
3. Makhalidwe a anthu odzipatula
Kutumiza kwa unidirectional: chizindikirocho chikhoza kutumizidwa kuchokera kumapeto olowera mpaka kumapeto, ndipo chizindikiro chotsitsimutsa chimaponderezedwa kapena kutengeka.
Kudzipatula kwakukulu: kumapereka mphamvu yopondereza kwambiri pamasinthidwe owonetsedwa, nthawi zambiri mpaka 20dB kapena kupitilira apo.
Kutayika kwapang'onopang'ono: kumatsimikizira kuti kutayika kwa mphamvu panthawi yotumiza chizindikiro kumakhala kochepa kwambiri.
4. Zomwe zimagwiritsidwa ntchito ndi zodzipatula
Chitetezo cha amplifier RF: kuteteza ma siginecha owoneka kuti asapangitse ntchito yosakhazikika kapena kuwonongeka kwa amplifier.
Njira yolumikizirana opanda zingwe: patulani gawo la RF mumayendedwe apansi a antenna.
Zida zoyesera: chotsani ma siginecha owoneka mu chida choyezera kuti mutsimikizire kulondola kwa mayeso.
III. Kodi kusankha bwino chipangizo?
Popanga mabwalo a RF kapena ma microwave, kusankha kozungulira kapena kudzipatula kuyenera kutengera zofunikira za kagwiritsidwe ntchito:
Ngati mukufuna kugawa kapena kuphatikiza ma siginecha pakati pa madoko angapo, ma circulator amakonda.
Ngati cholinga chachikulu ndikuteteza chipangizocho kapena kuchepetsa kusokonezedwa ndi ma siginecha owonetseredwa, zodzipatula ndizabwinoko.
Kuphatikiza apo, kuchuluka kwa ma frequency, kutayika kwa kuyika, kudzipatula komanso kukula kwa chipangizocho kuyenera kuganiziridwa mozama kuti zitsimikizire kuti zisonyezo za magwiridwe antchito a dongosolo linalake zimakwaniritsidwa.
IV. Tsogolo Zachitukuko
Ndi chitukuko chaukadaulo wamalumikizidwe opanda zingwe, kufunikira kwa miniaturization komanso magwiridwe antchito apamwamba a zida za RF ndi ma microwave kukukulirakulira. Zozungulira ndi zodzipatula zikukulanso pang'onopang'ono m'njira zotsatirazi:
Thandizo lafupipafupi: kuthandizira ma millimeter wave band (monga 5G ndi millimeter wave radar).
Mapangidwe ophatikizika: ophatikizidwa ndi zida zina za RF (monga zosefera ndi zogawa mphamvu) kuti muwonjezere magwiridwe antchito.
Mtengo wotsika komanso miniaturization: gwiritsani ntchito zida zatsopano ndi njira zopangira kuti muchepetse mtengo ndikusintha malinga ndi zofunikira za zida.
