Utshintsho oluchanekileyo lwe-impedance: Ukubonelela ngolungelelwaniso oluchanekileyo lokuguqulwa kwe-impedance (umz., 1: 1, 1: 4, 4: 1) ngonyamezelo oluqinileyo (± 5% eqhelekileyo) ukuhambelana neemfuno zenkqubo ephela kunye neyokuphela.
Ibhalansi ye-amplitude egqwesileyo / yesigaba: Gcina ibhalansi ye-amplitude ephezulu (ngokuqhelekileyo ± 0.5 dB) kunye nebhalansi yesigaba (ngokuqhelekileyo ± 5 degrees) ukwenzela ukuchaswa kwengxolo yendlela eqhelekileyo.
Ilahleko yokufaka ephantsi: Ukufumana ilahleko encinci yesignali (ephantsi njenge-0.5 dB ngokuxhomekeke kwifrikhwensi) ngokusebenzisa ukudibanisa magnetic kunye nelahleko ephantsi ye-dielectric materials.
2. Ukupakishwa okuphezulu kunye namandla okudibanisa
Imiba yefomu ebambeneyo: Iyafumaneka kwiipakethe ezisemgangathweni woshishino kunye nobungakanani besiko loyilo olunendawo.
Ukuhambelana kwe-Surface-Mount: Iyahambelana nezixhobo ezizenzekelayo zokukhetha kunye nendawo kunye neenkqubo zokuphinda zifakwe kwi-solder, eyenza ukuveliswa kwevolumu ephezulu.
Ulwakhiwo olomeleleyo: Sebenzisa i-ceramic, i-ferrite, okanye i-substrates ezihlanganisiweyo ezinesiphelo sokupheliswa (Ni/Sn, Au) esilungele iimeko zokusingqongileyo ezinzima.
I-ESD kunye nokukhuselwa kwe-thermal: Iimpawu zokukhusela ezihlanganisiweyo ukumelana neziganeko ze-ESD (ukuya kuthi ga kwi-2kV HBM) kunye namaqondo okushisa asebenzayo.
3. Ukuthembeka okuphuculweyo kunye nokulungelelaniswa kwesicelo esithile
Ukusebenza wedwa okuphezulu: Ukubonelela nge-port-to-port yodwa edlula i-20 dB ukuthintela ukudityaniswa komqondiso okungafunwayo.
Ukukwazi ukuphatha amandla: Inkxaso yamanqanaba ombane ukusuka kwi-milliwatts ukuya kwi-watts ezininzi ngokuxhomekeke kubungakanani bephakheji kunye noyilo.
Ukulungiswa okuthe ngqo kwemodeli: Ifumaneka kuhlengahlengiso olulungiselelwe usetyenziso oluthile (i-Wi-Fi, iselula, iBluetooth, njl.) ezineempawu ze-S-parameters.
Usetyenziso:
1. Iinkqubo zonxibelelwano ezingenazingcingo
Iziseko zeSellula: Isiseko se-transceivers kwisikhululo, iinkqubo ezinkulu ze-MIMO, kunye neeseli ezincinci ezifuna ukuthelekiseka kwe-impedance kunye nokwaliwa kweendlela eziqhelekileyo kwi-RF front-end.
Iimodyuli ze-Wi-Fi/Bluetooth: Nika amandla ukudityaniswa kwe-eriyali eyohlukileyo kwaye uphucule uvakalelo lwe-receiver kwi-2.4/5/6 GHz frequency bands.
Izixhobo ze-5G NR: Ukuququzelela i-mmWave kunye ne-sub-6 GHz ukusetyenzwa kwesignali kwisixhobo somsebenzisi kunye neziseko zenethiwekhi.
2. Ii-elektroniki zabathengi kunye nezixhobo ze-IoT
Ii-Smartphones/Iitafile: Yenza uyilo lwecandelo le-RF ecwengileyo ngomgangatho ophuculweyo wesiginali yeselula, iWi-Fi, kunye nabamkeli beGPS.
Ii-elektroni ezinxitywayo: Ukubonelela ngezisombululo zokuguqulwa komqondiso omncinci wokubeka iliso kwimpilo kunye neemodyuli zoqhagamshelwano.
