RF uye microwave switches inogona kutumira masaini zvakanaka munzira yekutapurirana.Mabasa ekuchinja aya anogona kuratidzwa neaya mana emagetsi paramita.Kunyangwe ma paramita akati wandei ane hukama nekuita kweRF uye microwave switch, mana anotevera ma paramita anoonekwa seakakosha nekuda kwehukama hwakasimba:
Kuiswa kwemurwere kwake ega
Isolation ndiko kudzikisira pakati pekupinda nekubuda kwedunhu.Icho chiyero chekucheka-kubvisa kushanda kwekuchinja.
Kuisa kurasikirwa
Kurasika kwekupinza (kunonziwo kurasikirwa kwekutapurirana) isimba rose rakarasika kana switch iri muhurumende.Kurasikirwa kwekupinza ndiyo inonyanya kukosha paramende kune vagadziri nekuti inogona kutungamira zvakananga mukuwedzera kweiyo system ruzha nhamba.
Kuchinja nguva
Kuchinja nguva kunoreva nguva inodiwa pakuchinja kubva pa "on" state kuenda pa "off" state uye kubva "off" state kuenda pa "on" state.Ino nguva inogona kusvika mamicroseconds emagetsi epamusoro switch uye nanoseconds epasi simba high speed switch.Tsanangudzo inonyanyozivikanwa yekuchinja nguva inguva inodiwa kubva pakupinza control voltage inosvika 50% kusvika kune yekupedzisira RF yekubuda simba inosvika 90%.
Simba rekugadzirisa simba
Uye zvakare, simba rekubata simba rinotsanangurwa seyakanyanya RF yekupinza simba iyo switch inogona kumira pasina chero zvachose kuparara kwemagetsi.
Solid state RF switch
Solid state RF switches inogona kukamurwa kuita isiri-reflection mhando uye kuratidza mhando.Iyo isiri-reflection switch inoshongedzerwa ne50 ohm terminal inoenderana resistor pane yega yega inobuda chiteshi kuti iwane yakaderera voltage standing wave ratio (VSWR) mune zvese zviri uye kunze kwenyika.Iyo terminal resistor yakaiswa pane inobuda chiteshi inogona kutora iyo chiitiko chiratidzo simba, nepo chiteshi chisina terminal chinofananidzira resistor chinoratidza chiratidzo.Kana chiratidzo chekuisa chinofanirwa kuparadzirwa muchinja, chiteshi chepamusoro chakavhurika chinobviswa kubva kune terminal inoenderana neresitorendi, nekudaro ichibvumira simba rechiratidzo kuti riparadzwe zvachose kubva pachinja.Iyo absorption switch inokodzera maapplication uko iyo echo ratidziro yeRF sosi inoda kudzikiswa.
Kusiyana neizvi, ma switch anovheneka haana kugadzirwa nematerminal resistors kudzikisa kurasikirwa kwekuiswa kwemadoko akavhurika.Reflective switches inokodzera maapplication asinganzwi kune yakakwira voltage yakamira wave ratio kunze kwechiteshi.Uye zvakare, mune inoratidzira switch, impedance yekufananidza inoonekwa nezvimwe zvinhu kunze kwechiteshi.
Chimwe chinocherechedzwa cheiyo solid-state switch ndiyo yavo dhiraivha maseketi.Mamwe marudzi e-soli-state switch akabatanidzwa pamwe nekuisa control voltage driver.Iyo yekupinza yekudzora voltage logic mamiriro eava madhiraivha anogona kuita chaiwo ekudzora mabasa - ichipa inodiwa ikozvino kuti ive nechokwadi chekuti diode inogona kuwana reverse kana kumberi bias voltage.
Electromechanical uye solid-state RF switches inogona kugadzirwa mumhando dzakasiyana dzezvigadzirwa zvine akasiyana dhizaini uye mhando dzekubatanidza - yakawanda coaxial switch zvigadzirwa zvine mafambisirwo ekushanda kusvika ku26GHz shandisa SMA zvibatanidza;Kusvikira ku40GHz, 2.92mm kana K-mhando yekubatanidza ichashandiswa;Kusvikira ku50GHz, shandisa 2.4mm connector;Kusvikira ku65GHz shandisa 1.85mm zvibatanidza.
