ʻO ka Bandwidth ʻoi aku ka liʻiliʻi
ʻO kahi kānana cavity Q kiʻekiʻe he bandwidth haiki. ʻO ia ka mea e ʻae ai i kahi ākea liʻiliʻi o nā alapine e hele i ka wā e hōʻole ana i nā alapine ma waho o kēia pae. No ka laʻana, loaʻa i kahi kānana cavity Q kiʻekiʻe i hoʻolālā ʻia no 2312.5MHz/2382.5MHz i kahi passband haiki loa, e hōʻoia ana i nā hōʻailona wale nō i loko o kēia mau alapine kikoʻī e ʻae ʻia e hele. Hōʻole maikaʻi kēia bandwidth haiki i nā hōʻailona o waho, e hōʻemi ana i ke keakea.
Hoʻomaikaʻi i ka hoʻokae pinepine ʻana
Hāʻawi nā kānana kiʻekiʻe-Q i ka hoʻokae pinepine ʻana. Hiki iā lākou ke hoʻokaʻawale pololei ma waena o ka alapine i makemake ʻia a me nā alapine ʻē aʻe kokoke. He mea koʻikoʻi kēia i nā ʻōnaehana kamaʻilio kahi e hoʻohana ʻia ai nā kaha pinepine. ʻO ka hoʻolālā kiʻekiʻe-Q e hōʻoia i ka hiki i ka kānana ke hōʻole pono i nā hōʻailona e kokoke ana akā ma waho o ka laina alapine i makemakeʻia, e pale ana iā lākou mai ka hoʻopiliʻana i ka hōʻailona makemake.
ʻO nā hiʻohiʻona ʻo Steeper Roll-off
Kiʻekiʻe-Qnā kānana luahōʻike i nā hiʻohiʻona ʻoi aʻe o ka roll-off. ʻO ka roll-off ka wikiwiki o ka kānana e hoʻemi ai i nā hōʻailona ke neʻe lākou mai ka passband. ʻO ka ʻōwili ʻoi aku ka ʻoi aku ka wikiwiki o nā hōʻailona ma waho o ka passband, e hoʻonui hou i ka hōʻole ʻana i nā hōʻailona o waho. ʻO kēia ʻōwili wiliwili e hōʻoia i ka hōʻemi iki ʻana o nā hōʻailona ma waho o ka pae alapine i makemake ʻia i ka amplitude.
Hoʻonui i ke koho
ʻO ke koho kiʻekiʻe o kahi kānana cavity kiʻekiʻe-Q hiki iā ia ke hoʻokaʻawale pono i nā hōʻailona ma muli o ko lākou mau alapine. He mea koʻikoʻi kēia koho no ka hōʻole ʻana i nā hōʻailona o waho. I loko o nā kaiapuni me ka nui o nā kaha alapine overlapping, hiki i kahi kānana Q kiʻekiʻe ke koho pololei i ka alapine i makemake ʻia aʻo ka hōʻole ʻana i nā poʻe ʻē aʻe, e hōʻoiaʻiʻo ana i ka kamaʻilio maʻemaʻe a me ke keakea ʻole.
ʻOi aku ka lōʻihi o kāna kānana
No ka hoʻokō ʻana i ka hana like me kahi kānana Q haʻahaʻa, pono kahi kānana cavity kiʻekiʻe-Q i kahi kānana lōʻihi. ʻO kēia lōʻihi lōʻihi e hiki ai ke hoʻopau maikaʻi i nā hōʻailona o waho. ʻO ka lōʻihi o ka kānana hoʻonui e hāʻawi i nā manawa hou no nā hōʻailona makemake ʻole e attenuated i ko lākou hele ʻana i ka kānana, e hopena i nā pae kiʻekiʻe.
Ka hopena ma nā ʻōnaehana kamaʻilio
ʻO ka hōʻole hōʻailona waho-o-band hoʻonui i hāʻawi ʻia e kiʻekiʻe-Qnā kānana luaʻoi aku ka maikaʻi ma nā ʻōnaehana kamaʻilio. E hōʻoia i ka hoʻomaʻemaʻe ʻana o nā hōʻailona i hoʻouna ʻia a loaʻa mai ka hoʻopili ʻana, hoʻomaikaʻi i ka hana holoʻokoʻa a me ka hilinaʻi o ka ʻōnaehana. No ka laʻana, ma nā ʻōnaehana lekiō ʻāina (LMR), hiki i nā kānana cavity kiʻekiʻe ke pale i ka hoʻopili ʻana ma waena o nā kahawai like ʻole, e hōʻoia ana i ka kamaʻilio maopopo a hilinaʻi.
