Ulwakhiwo oluqinileyo: Sebenzisa i-ceramic, i-ferrite, okanye i-composite substrates kunye ne-termination finishes (Ni/Sn, Au) ezifanelekileyo kwiimeko zokusingqongileyo ezinzima.
I-ESD kunye nokhuseleko lobushushu: Iimpawu zokhuseleko ezifakiweyo ziyamelana neziganeko ze-ESD (ukuya kuthi ga kwi-2kV HBM) kunye namaqondo obushushu okusebenza.
3. Ukuthembeka okuphuculweyo kunye nokwenza ngcono ukusetyenziswa kwesicelo esithile
Ukusebenza okuphezulu kokuzihlukanisa: Ukubonelela ngokuzihlukanisa ukusuka kwizibuko ukuya kwizibuko okuqhele ukugqitha i-20 dB ukuthintela ukudibana kwesignali okungafunekiyo.
Ubuchule bokuphatha umbane: Ixhasa amanqanaba ombane ukusuka kwi-milliwatts ukuya kwii-watts ezininzi kuxhomekeke kubungakanani bephakheji kunye noyilo.
Ukulungiswa kwemodeli ethile: Ifumaneka kwiindlela ezilungiselelwe usetyenziso oluthile (iWi-Fi, iselfowuni, iBluetooth, njl.njl.) ezineeparamitha ze-S ezichaziweyo.
