ʻO ka 3dB hybrid coupler kahi mea hana passive e hoʻokaʻawale i kahi hōʻailona hoʻokomo i ʻelua mau hōʻailona amplitude like me kahi ʻokoʻa 90°.I kēia manawa, aia ka nui o 800-2500MHz wide-band 3dB hybrid couplers, a me 3dB Hybrid couplers i hoʻohana ʻia e hoʻohui i nā hōʻailona o ka alapine like.Nā hiʻohiʻona: Hoʻohui GSM, DCS, DTV, WLAN, WCDMA, a me CDMA2000.ʻO CDMA800 a me nā hōʻailona ʻē aʻe i hoʻokahi a ʻoi aku paha nā kaha a hānai iā lākou i loko o ka ʻōnaehana hoʻohele;mana mana nui;ka hilinaʻi kiʻekiʻe (anti-vibration, anti-shock), ke kūpaʻa wela kiʻekiʻe, 3dB Hybrid Coupler corrosion resistance, a me ka wai.
3dB hybrid coupler introduction: ʻO ka 3dB hybrid coupler ua kapa ʻia ʻo ia ka like frequency combiner, 3dB Hybrid Coupler hiki iā ia ke hoʻomau i ka hoʻāʻo ʻana i ka mana hoʻouna i kekahi kuhikuhi o ka laina hoʻouna, 3dB Hybrid Coupler a hiki ke hoʻokaʻawale i kahi hōʻailona komo i ʻelua amplitudes like me 90° pae Hōʻailona maikaʻi ʻole.Hoʻohana nui ʻia ia no ka hui pū ʻana o nā hōʻailona he nui e hoʻomaikaʻi i ka helu hoʻohana ʻana o nā hōʻailona puka.Hoʻohana nui ʻia ia i loko o ka ʻōnaehana uhi i loko no ka hui pū ʻana o nā hōʻailona base station.He hopena maikaʻi kona ma kēia wahi.
Ka hoʻohana ʻana i ke alahaka 3dB: ʻO ka nalowale o ka hoʻokomo ʻana o ke alahaka 3dB ʻo 3.2, ʻo ka hoʻokaʻawale ʻana he 25, a ʻo ka nalu kū ʻana he awelika.Akā, aia ʻelua mau puka puka, no ka laʻana, 3dB Hybrid Coupler ʻelua hoʻokomo 30 output ʻelua 27. Hiki ke hoʻonohonoho pono ʻia ka puka puka o ke alahaka 3dB, ʻelua hoʻokomo a hoʻokahi puka, hoʻokahi hoʻokomo a ʻelua hoʻopuka, 3dB Hybrid Coupler ʻelua. hiki ke hoʻokomo a me ʻelua puka, hoʻohui ʻia hoʻokahi awa hou E hoʻouka i kahi ukana me ka mana lawa.Inā ʻaʻole pili ka ukana, e hoʻokaʻawale ʻia ka 3dB hybrid coupler mai ka hale hana, ʻaʻohe hopena e like me kahi ukana ʻē aʻe.Eia naʻe, ke kiʻekiʻe ka lākiō hawewe kū, hiki ke hoʻohana ʻia ʻo 3dB Hybrid Coupler wale nō.Eia kekahi, pono e noʻonoʻo ʻia ka mana kūpaʻa o ka hāmeʻa.
E like me ka mea hana oNā ʻāpana passive RF, hiki iā mākou ke hoʻolālā kūikawā i nā mea hoʻokaʻawale mana, nā mea hoʻohui, a me nā mea hoʻohui e like me kāu hopena, no laila ke manaʻolana nei hiki iā mākou ke kākoʻo iā ʻoe i kēlā me kēia manawa.
