ʻO ke kuleana koʻikoʻi o nā kānana haʻahaʻa LC i nā ʻōnaehana uila hou

He kuleana koʻikoʻi ko nā kānana haʻahaʻa LC i ka hana ʻana i nā hōʻailona uila. Hiki iā lākou ke kānana pono i nā hōʻailona alapine haʻahaʻa a kāohi i ka walaʻau alapine kiʻekiʻe, a laila e hoʻomaikaʻi ana i ka maikaʻi o nā hōʻailona. Hoʻohana ia i ka synergy ma waena o ka inductance (L) a me ka capacitance (C). Hoʻohana ʻia ka Inductance e pale i ka hele ʻana o nā hōʻailona alapine kiʻekiʻe, ʻoiai ʻo ka capacitance e hoʻouna a hoʻonui i nā hōʻailona alapine haʻahaʻa. ʻO kēia hoʻolālā e hoʻolilo i nā kānana haʻahaʻa LC i mea nui i nā ʻōnaehana uila he nui, ʻoi aku hoʻi i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka hōʻailona a me ka hōʻemi ʻana i ka walaʻau.

Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ke ulu nei ke koi no nā hōʻailona kiʻekiʻe ma nā kahua e like me ke kamaʻilio uea ʻole, ka hana leo, a me ka hoʻouna kiʻi. Ma ke ʻano he ʻāpana koʻikoʻi o ka hana hōʻailona, ​​​​loaʻa i nā kānana haʻahaʻa LC nā manaʻolana noi ākea ma kēia mau kahua. I loko o nā ʻōnaehana kamaʻilio uea ʻole, hiki i nā kānana haʻahaʻa LC ke kānana pono i nā hōʻailona hoʻopilikia alapine kiʻekiʻe a hoʻomaikaʻi i ka maikaʻi o ka hōʻailona ma ka ʻaoʻao e loaʻa ana; ma ka ʻaoʻao e hoʻouna ana, hiki iā ia ke hōʻoia i ka hoʻokō ʻana o ka bandwidth hōʻailona a pale i ka hoʻopilikia ʻana me nā hui alapine ʻē aʻe. Ma ke kahua o ka hana leo, kōkua nā kānana haʻahaʻa LC i ka wehe ʻana i ka walaʻau alapine kiʻekiʻe a me nā hōʻailona hele hewa i nā hōʻailona leo, e hāʻawi ana i nā hopena leo maopopo a maʻemaʻe. ʻOi loa i nā ʻōnaehana leo, he mea nui nā kānana no ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kani. Ma ke ʻano o ka hana kiʻi, hoʻemi ka kānana haʻahaʻa LC i ka walaʻau alapine kiʻekiʻe i ke kiʻi, kāohi i ka hoʻopilikia kala, a hōʻoia i ka maopopo a me ka ʻoiaʻiʻo o ke kiʻi.

ʻO nā hiʻohiʻona nui o ka kānana haʻahaʻa LC e komo pū me ka pane alapine maʻalahi a me ka linearity pae maikaʻi. Ma lalo o ke alapine ʻoki, ua liʻiliʻi ka attenuation hōʻailona, ​​​​e hōʻoiaʻiʻo ana i ka kūpaʻa o ka hōʻailona; ma luna o ke alapine ʻoki, ua kiʻekiʻe ka attenuation hōʻailona, ​​​​e kānana pono ana i ka walaʻau alapine kiʻekiʻe. Eia kekahi, ʻo kona linearity pae e hōʻoiaʻiʻo ana e hiki i ka hōʻailona ke mālama i kona pilina pae mua ma hope o ka kānana ʻana, he mea nui loa ia no nā noi e like me ka hana leo a me ka hoʻouna kiʻi.

Me ka holomua o ka ʻenehana, e hoʻomau ka kānana haʻahaʻa LC i ka hana hou a me ka hoʻomohala ʻana i ke ala o ka miniaturization, hoʻohui, a me nā noi alapine kiʻekiʻe, e hoʻonui hou ana i kāna mau wahi noi. I ka wā e hiki mai ana, e pāʻani nā kānana haʻahaʻa LC i kahi hana nui aʻe i nā ʻōnaehana uila hou aʻe, e paipai ana i ka hoʻomohala ʻepekema a me ka ʻenehana a me ka holomua o ka ʻoihana.
