Chotetezera Chotsogozedwa
Cholumikizira cha Lead ndi cholumikizira cholumikizidwa chomwe chimagwiritsidwa ntchito kwambiri m'munda wamagetsi, chomwe chimagwiritsidwa ntchito kwambiri kuwongolera ndikuchepetsa mphamvu ya ma siginecha amagetsi. Chimagwira ntchito yofunika kwambiri pakulankhulana opanda zingwe, ma RF circuits, ndi ntchito zina zomwe zimafuna kuwongolera mphamvu ya ma siginecha.
Zotetezera za Lead nthawi zambiri zimapangidwa posankha zinthu zoyenera za substrate {nthawi zambiri aluminium oxide(Al2O3), aluminium nitride(AlN), beryllium oxide(BeO), ndi zina zotero} kutengera mphamvu ndi ma frequency osiyanasiyana, komanso kugwiritsa ntchito njira zotsutsana (filimu yokhuthala kapena njira zopyapyala za filimu).
Kapangidwe kake kamapezeka mukapempha.

Flanged Attenuator
Flanged attenuator ndi RF leaded attenuator yokhala ndi ma flanges oyika. Imapangidwa polumikiza RF leaded attenuator pa flange. Ili ndi makhalidwe ofanana ndi ma lead attenuator komanso kuthekera kotulutsa kutentha. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri pa flange zimapangidwa ndi mkuwa wokutidwa ndi nickel kapena siliva. Ma chips a attenuation amapangidwa posankha kukula koyenera ndi ma substrate {nthawi zambiri beryllium oxide(BeO), aluminium nitride(AlN), aluminium oxide(Al2O3), kapena zinthu zina zabwino za substrate} kutengera zofunikira zosiyanasiyana zamphamvu ndi ma frequency, kenako nkuziwotcha kudzera mu resistance ndi circuit printing. Flanged attenuator ndi circuit yolumikizidwa yomwe imagwiritsidwa ntchito kwambiri mu electronic field, makamaka imagwiritsidwa ntchito kuwongolera ndikuchepetsa mphamvu ya ma signaling amagetsi. Imagwira ntchito yofunika kwambiri pakulankhulana opanda zingwe, ma RF circuits, ndi ntchito zina zomwe zimafuna kuwongolera mphamvu ya ma signaling.

Chotetezera Chosinthika cha RF
Chochepetsera mphamvu ya chizindikiro ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kuwongolera mphamvu ya chizindikiro, chomwe chingachepetse kapena kuwonjezera mphamvu ya chizindikiro ngati pakufunika kutero. Nthawi zambiri chimagwiritsidwa ntchito kwambiri m'makina olumikizirana opanda zingwe, muyeso wa labotale, zida zamawu, ndi zina zamagetsi.
Ntchito yaikulu ya chochepetsera mphamvu ya chizindikiro ndikusintha mphamvu ya chizindikiro mwa kusintha kuchuluka kwa kuchepa kwa mphamvu komwe kumadutsa. Chingathe kuchepetsa mphamvu ya chizindikiro cholowera ku mtengo womwe mukufuna kuti chigwirizane ndi zochitika zosiyanasiyana zogwiritsira ntchito. Nthawi yomweyo, zochepetsera mphamvu zosinthika zimathanso kupereka magwiridwe antchito abwino ofananiza chizindikiro, kuonetsetsa kuti ma frequency ayankhidwe molondola komanso mokhazikika komanso mawonekedwe a mafunde a chizindikiro chotulutsa.
Kapangidwe kake kamapezeka mukapempha.
