Nā kānana RF CAVITY: He aha kā lākou e hana ai
Loaʻa iā lākou nā poloka metala nui aʻe me nā mea hoʻohui RF liʻiliʻi (2 no nā kānana a me 3 no nā duplexers e hoʻohui i nā hōʻailona Tx a me Rx i hoʻokahi awa antenna).E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, loaʻa kēia mau kānana i nā wili he nui ma kekahi ʻaoʻao a ʻoi aku paha o ko lākou kino.ʻO kekahi o kēia mau wili he mau wili, a ʻo nā mea ʻē aʻe e hoʻopaʻa i ka pā luna i ka chassis.
I mea e hōʻemi ai i nā poho RF a hoʻokō i ka Q kiʻekiʻe a i ʻole ka kānana koho e pono ai e loaʻa nā poho haʻahaʻa i loko o ka passband kānana a me ka hōʻole ʻana i waho o ka passband kānana, ua uhi mau ʻia ke kino alumini (me ke kālā, ke keleawe, a i ʻole ke gula, akā wale nō. no nā noi ākea).
Ma nā pūnaewele uea ʻole a pau mai ka 1G a i ka 5G, a me nā ʻōnaehana kamaʻilio kīwila a me ka pūʻali koa, ʻo RF Cavity Filters i lilo a hoʻomau i ka hana o ka ʻoihana uila.Loaʻa iā lākou kahi ākea ākea ākea, mai ka 50 MHz a ʻoi aku ma mua o 20 GHz.Ma muli o ko lākou mau haʻahaʻa haʻahaʻa haʻahaʻa, liʻiliʻi lākou i ka piʻi ʻana o ke alapine (ʻo ka wikiwiki o ke kukui mau a helu ʻia ʻo ia ka huahana o ka frequency signal RF a me kona mau nalu).
ʻOiai ʻo ka passband no ka hapa nui o nā noi kaulana ma waena o 1% a me 10% o ke alapine hana, hāʻawi ʻo RF Cavity Filters i kahi ākea o nā noi kūpono no ka mea hiki ke hoʻololi ʻia kā lākou passband mai lalo o 0.5% a hiki i ka 20% o ka pinepine hana. .No ka loaʻa ʻana o ka hana hoʻokipa maikaʻi loa i kahi kaiapuni RF maoli, ʻo ka hapa nui, inā ʻaʻole nā mea āpau, hoʻohana nā ʻōnaehana uila i nā kānana RF Cavity ma waena o ka Antenna a me Radio (bandlimited ka LNA input signal e hōʻole i nā alapine haʻahaʻa a me luna ma waho o ka hana ʻōnaehana) .
ʻOiai ʻoi aku ka leo o nā hōʻailona Tx ma mua o nā hōʻailona hoʻokipa ma 120 a 150 dB, hoʻohana pū ʻia nā kānana RF Cavity ma ka hōʻailona Tx e hōʻoia i ka palena ʻole o ka walaʻau a me ka hoʻokuʻu ʻana o PA a ʻaʻole pili iā lākou iho a i ʻole kekahi ʻano ʻōnaehana uila.
