Microstrip Isolator
Microstrip izigunga ni ibikoresho bisanzwe bikoreshwa na RF hamwe na microwave ikoreshwa mugukwirakwiza ibimenyetso no kwigunga mumuzunguruko.Ikoresha tekinoroji ya firime yoroheje kugirango ikore uruziga hejuru ya ferrite izunguruka, hanyuma ikongeramo umurima wa magneti kugirango ubigereho.Kwishyiriraho microstrip izitandukanya muri rusange ikoresha uburyo bwo kugurisha intoki imirongo yumuringa cyangwa guhuza insinga za zahabu.Imiterere ya microstrip izitandukanya iroroshye cyane, ugereranije na coaxial na yashyizwemo.Itandukaniro rigaragara cyane ni uko nta cavit ihari, kandi umuyobozi wa microstrip isolator akorwa hakoreshejwe firime yoroheje (vacuum sputtering) kugirango ikore igishushanyo mbonera kuri ferrite.Nyuma ya electroplating, kiyobora yakozwe ifatanye na rotate ferrite substrate.Ongeraho urwego rwokwirinda hejuru yishusho, hanyuma ukosore umurima wa rukuruzi.Hamwe nuburyo bworoshye, microstrip isolator yahimbwe.
