Pakazosvika ma1950 mafirita emuchina aive achigadzirwa sezvikamu zvakazvimiririra zvekushandisa mumaradio transmitter uye epamusoro-magumo vanogamuchira. Iyo yakakwira "mhando factor", Q, iyo michina resonators inogona kuwana, yakakwira zvakanyanya kupfuura iyo yemagetsi LC wedunhu, yakaita kuti kugadzirwa kwemafirita emuchina ave nekusarudzika kwakanaka. Kusarudzika kwakanaka, kuve kwakakosha munhepfenyuro vanogamuchira, kwakaita kuti mafirita akadaro anyanye kukwezva. Vaongorori vemazuva ano vari kushanda pamafirita e microelectromechanical, michina inoenderana nemagetsi akabatanidzwa. Mubvunzo: Ichi chishandiso chakatanga kushandiswa chii?
