Mune microwave yekuyedza masisitimu, RF uye microwave switch anoshandiswa zvakanyanya kune chiratidzo chekufambisa pakati pezviridzwa neDUTs.Nekuisa switch mune switch matrix system, masaini kubva kune akawanda zviridzwa anogona kuendeswa kune imwe kana anopfuura maDUTs.Izvi zvinobvumira kuti bvunzo dzakawanda dzipedzwe uchishandisa mudziyo mumwe chete wekuyedza pasina kudiwa kwekuwanzo bviswa uye kubatana zvakare.Uye inogona kuwana otomatiki maitiro ekuyedza, nekudaro ichivandudza kuyedza kugona munzvimbo dzekugadzira hukuru.
Zviratidzo zvekushanda zvakakosha zvekuchinja zvikamu
Kugadzirwa kwemazuva ano kwepamusoro-soro kunoda kushandiswa kwepamusoro-kuita uye kudzokororwa kushandura zvikamu mukuedza zviridzwa, kushandura nzvimbo, uye otomatiki ekuyedza masisitimu.Aya ma switch anowanzo kutsanangurwa zvichienderana neanotevera maitiro:
Frequency range
Iyo frequency renji yeRF uye microwave application inotangira pa100 MHz mumasemiconductors kusvika 60 GHz mune setiraiti yekutaurirana.Iwo ekuyedza anonamirwa ane akafara ekushanda frequency mabhendi akawedzera kuchinjika kweyeyedzo system nekuda kwekuwedzera kweiyo frequency kufukidzwa.Asi yakawanda yekushanda frequency inogona kukanganisa mamwe akakosha paramita.
Kuisa kurasikirwa
Kurasikirwa kwekupinza kwakakoshawo pakuyedzwa.Kurasikirwa kwakakura kupfuura 1 dB kana 2 dB kunoderedza mwero wepamusoro wechiratidzo, ichiwedzera nguva yekukwira nekudonha mipendero.Munzvimbo dzekushandiswa kwepamusoro-soro, kufambisa kwesimba kunoshanda dzimwe nguva kunoda mutengo wakanyanya, saka kurasikirwa kwakawedzerwa kunounzwa nemagetsi emagetsi munzira yekutendeuka kunofanirwa kudzikiswa zvakanyanya sezvinobvira.
Dzorera kurasikirwa
Kurasikirwa kwekudzoka kunoratidzwa mudB, inova chiyero chevoltage yakamira wave ratio (VSWR).Kurasikirwa kwekudzoka kunokonzerwa ne impedance mismatch pakati pemaseketi.Mune iyo microwave frequency renji, hunhu hwezvinhu uye saizi yetiweki zvikamu zvinoita basa rakakosha pakuona impedance yekufananidza kana kusawirirana kunokonzerwa nekugovera mhedzisiro.
Kuenderana kwekuita
Iko kuenderana kwekuderera kwekuisa kurasikirwa kuita kunogona kuderedza zvisizvo zvisizvo zvisizvo munzira yekuyera, nekudaro zvichivandudza kuyerwa kwechiyero.Kusagadzikana uye kuvimbika kwekuchinja kwekuita kunovimbisa kuyerwa kwechiyero, uye kudzikisa mutengo wevaridzi nekuwedzera kutenderera kutenderera uye kuwedzera yekuyedza system yekushanda nguva.
Kuiswa kwemurwere kwake ega
Isolation ndiyo dhigirii yekuderedzwa kwezviratidzo zvisingabatsiri zvakaonekwa pachiteshi chekufarira.Pamafambiro akakwirira, kuzviparadzanisa kunova kwakakosha zvakanyanya.
VSWR
Iyo VSWR yekuchinja inotemerwa nemakanika zviyero uye kushivirira kwekugadzira.VSWR ine urombo inoratidza kuvepo kwemukati maratidziro anokonzerwa ne impedance mismatch, uye zviratidzo zveparasitic zvinokonzerwa neaya maratidziro zvinogona kutungamira mukukanganiswa kwechiratidzo chepakati (ISI).Aya maratidziro anowanzoitika padhuze nechokubatanidza, saka yakanaka yekubatanidza inofananidzwa uye chaiyo yekubatanidza mutoro zvinhu zvakakosha zvekuyedza zvinodiwa.
Kuchinja speed
Kumhanyisa kwekuchinja kunotsanangurwa senguva inodiwa kuti switch port (switch arm) ibve kubva "pa" kuenda "kudzima", kana kubva "kudzima" kuenda "ku".
Yakagadzikana nguva
Nekuda kwekuti nguva yekuchinja inongotaura kukosha kunosvika 90% yekutsiga/yekupedzisira kukosha kweiyo RF chiratidzo, nguva yekugadzikana inova yakakosha kuita kweakasimba-nyika switch pasi pezvinodiwa nekurongeka uye nemazvo.
Kutakura simba
Simba rekutakura rinotsanangurwa sekukwanisa kwekushandura kutakura simba, iro rinonyatsoenderana nekugadzirwa uye zvinhu zvinoshandiswa.Kana paine RF / microwave simba pane switch port panguva yekuchinja, kupisa kunopisa kunoitika.Cold switching inoitika kana chiratidzo chesimba chabviswa usati wachinja.Cold switching inowana yakaderera yekubata pamusoro kushushikana uye hupenyu hurefu.
Kugumisa
Mune akawanda maapplication, 50 Ω kuremerwa kwemutoro kwakakosha.Kana iyo switch yakabatana kune inoshanda mudziyo, iyo inoratidzwa simba renzira isina kumisa mutoro inogona kukuvadza sosi.Electromechanical switches inogona kukamurwa kuita mapoka maviri: ayo ane kumisa mutoro uye ayo asina kumisa mutoro.Solid state switches inogona kukamurwa kuita marudzi maviri: absorption type uye reflection type.
Video leakage
Vhidhiyo kuvuza inogona kuoneka separasitic masiginecha anoonekwa pane switch RF chiteshi kana pasina RF chiratidzo chiripo.Aya masaini anobva kumasaisai anogadzirwa nemutyairi wekuchinja, kunyanya kubva kumberi voltage spikes inodiwa kutyaira yakanyanya-kumhanya switch yePIN diode.
Upenyu hwebasa
Hupenyu hwesevhisi hurefu huchadzikisa mutengo uye zvipingamupinyi zvebhajeti rekuchinja kwega kwega, zvichiita kuti vagadziri vawedzere kukwikwidza mumusika wemazuva ano wemitengo.
Chimiro chekuchinja
Iwo akasiyana masisitimu mafomu ekuchinja anopa shanduko yekuvaka yakaoma matrices uye otomatiki ekuyedza masisitimu eakasiyana maapplication uye ma frequency.
Iyo yakakamurwa zvakananga kuita imwe muzviviri kunze (SPDT), imwe muvatatu kunze (SP3T), maviri mune maviri kunze (DPDT), nezvimwe.
