A kānana band-passnā hana:

Pono kahi kānana kūpono e loaʻa kahi passband pālahalaha loa, no ka laʻana, ʻaʻohe loaʻa i loko o ka passband a i ʻole ka attenuation ma nā alapine āpau ma waho o ka passband e hoʻemi loa ʻia. Eia kekahi, ʻo ka hoʻololi ʻana o ka pass-band i kahi alapine liʻiliʻi loa e hoʻopau. ʻO ka ʻoiaʻiʻo, ʻaʻohe kānana band-pass kūpono. ʻAʻole hiki i ke kānana ke manaʻo e hoʻemi loa ʻia nā alapine āpau ma waho o ka alapine, ʻoiai, aia kahi band e hoʻemi ʻia akā ʻaʻole ka laulā i hoʻokaʻawale ʻia. ʻO kēia ka mea maʻamau i kapa ʻia ʻo ka hanana roll-off kānana, a me ka attenuation ma dB i kēlā me kēia ʻumi makahiki e hōʻike. ʻO ka maʻamau, hoʻāʻo ka hoʻolālā kānana e hōʻoia i ka rolloff e hoʻopili kokoke i ka laulā o ka hana maikaʻi o ia hoʻolālā kānana. Eia nō naʻe, me ka liʻiliʻi o ka laulā roll-off, ʻaʻole pālahalaha ka pass-band - ua hoʻomaka e ʻike ʻia e "ripple". ʻIke nui ʻia kēia hanana ma ka lihi passband, ua kapa ʻia kēia hopena ʻo ka hanana Gibbs.

Kānana lua

ʻO ke kānana lua he kānana microwave me kahi ʻano lua resonant. Hiki i kahi lua ke like me kahi inductance ma ke ʻano like me kahi capacitor e hana i kahi kahua resonant e hoʻokō ai i ka hana kānana microwave. Ke hoʻohālikelike ʻia me nā ʻano kānana microwave ʻē aʻe, he ʻano paʻa ko ke kānana lua, hana paʻa a hilinaʻi hoʻi, waiwai Q kiʻekiʻe, hoʻolaha wela maikaʻi, a mamao loa kāna passband parasitic kiʻekiʻe. No laila, hoʻohana ʻia ke kānana lua ma nā kikowaena kamaʻilio nui. He mea maʻamau ka hoʻohana ʻana o ka hāmeʻa.

ʻO Sichuan Keenlion Microwave kekahi o nā mea hoʻolako ʻāpana RF/Microwave. ʻO nā huahana nui ka mea hoʻokaʻawale mana, ka kānana band pass, ka coupler, ka duplexer. ʻO nā huahana ma lalo nei he microstrip power divider, directional coupler, band pass filter, Hybrid Bridge, Microwave Isolator, Microwave Circulator, Passive Components VHF Duplexer, Combiner, etc. Ua lilo ʻo Sichuan Keenlion Microwave i ʻoihana R&D, hana, kūʻai aku a me ka lawelawe ʻenehana kiʻekiʻe hou. Hoʻohana nui ʻia nā huahana ma ka paging lekiō, ke kīwī kikohoʻe, ka ʻōnaehana kamaʻilio microwave (GSM, 3G, Wimax, LTE), ka ʻōnaehana radar a me nā ʻōnaehana RF like ʻole. Kūʻai ʻia nā huahana Sichuan Keenlion Microwave ma ka honua holoʻokoʻa a mahalo nui ʻia. Ma ke ʻano he hoʻokahi o nā mea hana a me nā mea hoʻokuʻu aku o ka microwave filed, kaulana ka mākeke leo Sichuan Keenlion Microwave, nā kahawai ʻoihana ākea, ke kahua kūʻai aku paʻa a me ka hoʻokūkū mākeke ikaika.

Hiki iā mākou ke hoʻopilikino i nā ʻāpana passive rf e like me kāu mau koi. Hiki iā ʻoe ke komo i ka ʻaoʻao hoʻopilikino e hāʻawi i nā kikoʻī āu e pono ai.
