Ukutshintsha kwe-RF kunye ne-microwave kunokuthumela imiqondiso ngokufanelekileyo kwindlela yothumelo.Imisebenzi yolu tshintsho inokubonakaliswa ngemilinganiselo emine esisiseko yombane.Nangona iiparamitha ezininzi zinxulumene nokusebenza kweRF kunye nokutshintsha kwe-microwave, ezi parameters zine zilandelayo zithathwa njengezibalulekileyo ngenxa yonxulumano olunamandla:
Ukubekwa wedwa
I-Isolation yi-attenuation phakathi kwegalelo kunye nemveliso yesekethe.Ngumlinganiselo wokusikwa kokusebenza kokutshintsha.
Ilahleko yokufaka
Ilahleko yokufaka (ekwabizwa ngokuba yilahleko yothumelo) ngamandla ewonke alahlekileyo xa iswitshi ikwimo.Ilahleko yokufaka yeyona parameter ibaluleke kakhulu kubayili kuba inokukhokelela ngokuthe ngqo ekwandeni kwenani lengxolo yenkqubo.
Ukutshintsha ixesha
Ixesha lokutshintsha libhekisa kwixesha elifunekayo ekutshintsheni ukusuka kwimeko ethi "on" ukuya kwimeko "yokucima" kwaye ukusuka kwimeko "yokucima" ukuya kwimeko "yokuvula".Eli xesha linokufikelela kwii-microseconds zokutshintsha kwamandla aphezulu kunye nee-nanoseconds zamandla aphantsi okutshintsha kwesantya esiphezulu.Eyona nkcazelo ixhaphakileyo yokutshintsha ixesha lixesha elifunekayo ukusuka kumbane wokulawula igalelo ukuya kuma-50% ukuya kumandla okugqibela eRF aphumayo afikelela kuma-90%.
Umthamo wokwenza amandla
Ukongeza, amandla okuphatha amandla achazwa njengawona mandla aphezulu e-RF afakwayo isitshixo esinokumelana nawo ngaphandle kokuthotywa kombane okusisigxina.
Ukutshintsha kweRF yemeko eqinileyo
Izitshixo ze-RF zesimo esiqinileyo zinokwahlulwa zibe luhlobo olungabonisiyo kunye nohlobo lokubonisa.Umtshini ongabonisiyo uxhotyiswe nge-50 ohm terminal ehambelana ne-resistor kwizibuko ngalinye lemveliso ukuphumeza umlinganiselo we-voltage ophantsi wokuma wamaza (VSWR) kuzo zombini iindawo ezivuliweyo nangaphandle.Isichasi setheminali eseti kwizibuko lemveliso sinokufunxa amandla omqondiso wesiganeko, ngelixa izibuko ngaphandle kwetheminali yokuchasana nokuthelekisa iyakubonisa umqondiso.Xa isignali yegalelo kufuneka isasazwe kwiswitshi, i-port evulekileyo engentla ikhutshwe kwi-terminal ehambelana ne-resistor, ngaloo ndlela ivumela amandla omqondiso ukuba asasazwe ngokupheleleyo kwi-switch.Iswitshi yokufunxa ifanelekile kwizicelo apho ukubonakaliswa kwe-echo yomthombo weRF kufuneka kuncitshiswe.
Ngokwahlukileyo, iiswitshi ezibonisayo azixhotyiswanga zixhathisi zetheminali ukunciphisa ilahleko yokufakwa kwamazibuko avulekileyo.Iiswitshi ezibonisa ukukhanya zilungele usetyenziso olungenaluvelwano kumlinganiselo wamaza ombane aphezulu omileyo ngaphandle kwezibuko.Ukongeza, kutshintsho olubonakalisayo, ukuthelekisana kwe-impedance kwenziwa ngamanye amacandelo ngaphandle kwezibuko.
Enye into ephawulekayo yokutshintsha kwe-slid-state yizijikelezo zabo zokuqhuba.Ezinye iintlobo zokutshintsha kwe-slid-state zidityaniswe ne-input control control drivers.Igalelo lolawulo lwevoltage logic state yaba baqhubi banokufezekisa imisebenzi ethile yolawulo - ukubonelela ngoku ngokuyimfuneko ukuqinisekisa ukuba i-diode inokufumana i-voltage ye-bias ebuyela umva okanye phambili.
I-Electromechanical kunye ne-slid-state RF iiswitshi zinokwenziwa kwiimveliso ezahlukeneyo ezineenkcazo zokupakisha ezahlukeneyo kunye neentlobo zesinxibelelanisi - uninzi lweemveliso zokutshintsha kwe-coaxial ezinezandi zokusebenza ukuya kuthi ga kwi-26GHz zisebenzisa izihlanganisi ze-SMA;Ukuya kuthi ga kwi-40GHz, 2.92mm okanye isidibanisi sodidi lwe-K siya kusetyenziswa;Ukuya kuthi ga kwi-50GHz, sebenzisa isinxibelelanisi se-2.4mm;Ukuya kuthi ga kwi-65GHz sebenzisa izihlanganisi eziyi-1.85mm.
