LC kānana hele haʻahaʻa LLPF-900/1200-2S

ʻO ka LC structure Low Pass Filter, model LLPF-900/1200-2S, he hopena paʻa a maikaʻi no ka kānana ʻana i ka walaʻau kiʻekiʻe me ka ʻae ʻana i nā hōʻailona haʻahaʻa e hele i loko. Hana ʻia e leder-mw, ua hoʻolālā ʻia kēia kānana me ka pololei o ka noʻonoʻo, e hoʻolako ana i nā noi kahi mea koʻikoʻi koʻikoʻi me ka ʻole o ka hoʻokō ʻana.

Me ka ʻoki ʻoki alapine o 900MHz a 1200MHz, ʻo ka LLPF-900/1200-2S e hoʻopau pono i nā alapine kiʻekiʻe i makemake ʻole ʻia, e hōʻoiaʻiʻo ana i ka hoʻouna ʻana i nā hōʻailona maʻemaʻe i nā ʻōnaehana kamaʻilio, nā laina ʻikepili, a me nā kaʻa uila like ʻole. ʻO kona liʻiliʻi liʻiliʻi he mea kūpono ia no ka hoʻohui ʻana i nā papa PCB paʻa paʻa a i ʻole ke hoʻemi ʻana i ka nui o ka papa.

Kūkulu ʻia me ka hoʻohana ʻana i nā ʻāpana kiʻekiʻe, me nā inductors i koho pono ʻia a me nā capacitors, ʻo kēia kānana haʻahaʻa haʻahaʻa e hōʻoiaʻiʻo i nā hiʻohiʻona maikaʻi loa o ka hoʻokomo ʻana a me ka hiki ke hoʻopau. Hoʻonui ka hoʻolālā 2-pole i ka hiki ke kānana e hoʻemi i nā harmonics kiʻekiʻe a me ka walaʻau, e hāʻawi ana i kahi roll-off steeper i hoʻohālikelike ʻia me nā hoʻolālā hoʻokahi.

ʻOiai ka liʻiliʻi liʻiliʻi, mālama ka LLPF-900/1200-2S i nā kikoʻī uila kupaianaha, e like me ka poho haʻahaʻa i loko o ka passband a me ka hōʻole kiʻekiʻe o waho. Mālama kēia i ka hōʻemi liʻiliʻi o ka hōʻailona no ka laulima alapine i manaʻo ʻia ʻoiai ke kāohi pono nei i nā alapine makemake ʻole i hiki ke hoʻopilikia i ka hana ʻōnaehana.

I ka hōʻuluʻulu ʻana, kū ka leder-mw LCstructure Low Pass Filter LLPF-900/1200-2S ma ke ʻano he koho maʻamau a hilinaʻi no nā mea hoʻolālā e ʻimi nei i kahi hopena kiʻekiʻe, mālama wahi no nā pono kānana haʻahaʻa i loko o kahi ākea o ka uila. a me nā polokalamu kelepona.
