75 ohms Nā mea hoʻēmi 75Ω Paʻa 75 Ohms Paʻa
ʻO ka attenuator 75 ohms kahi ʻano attenuator i kapa ʻia no kona impedance o 75 ohms.
He ʻāpana passive ia i hoʻohana ʻia e hoʻoponopono i ka ikaika hōʻailona o kahi kaapuni, pale kahi attenuator 75Ω i ka hoʻonui nui ʻana a me ka hoʻopilikia ʻana o ka hōʻailona, a pale i ka hāʻule ʻana i hoʻokumu ʻia e ka overload hōʻailona.
ʻO nā ʻano nui o nā attenuators paʻa 75Ω:
1. Hoʻohālikelike impedance: Hoʻohālikelike ka impedance attenuator paʻa 75 Ohms i ka impedance hiʻohiʻona o ka laina hoʻoili hōʻailona o nā lako wikiō, ka hoʻolaha kīwī a me ka ʻōnaehana kīwī uwea, a pēlā e hōʻemi ai i ka noʻonoʻo a me ka nalowale o ka hōʻailona hoʻoili.
2. Haʻahaʻa ka hoʻopilikia ʻana: Hiki i ka attenuator ke hōʻemi i ka ikaika o ka hōʻailona me ka ʻole o ka hoʻokomo ʻana i ka hoʻopilikia hou a i ʻole ke komo ʻana o ka hōʻailona.
3. Hilinaʻi kiʻekiʻe: Ma muli o ka ʻoiaʻiʻo he mau ʻāpana passive nā attenuators a ʻaʻohe ʻāpana neʻe, hilinaʻi loa lākou a ʻaʻole pono ka mālama a hoʻololi paha.
Hoʻohana pinepine ʻia nā attenuators 75 ohms i nā noi aʻe:
1. Ma nā pūnaewele kīwī uwea a me nā pūnaewele kīwī kikohoʻe, hoʻohana ʻia ia e hoʻoponopono i ka ikaika hōʻailona a hōʻemi i ka hoʻohuli ʻana a me ka nalowale o ka hōʻailona.
2. I ka wā o ka hana ʻana a me ka hoʻouna ʻana i nā wikiō hoʻonā kiʻekiʻe a me ka wehewehe kiʻekiʻe, e kāohi i ka ikaika o ka hōʻailona a mālama i ka maikaʻi o ka hoʻololi ʻana.
3. I loko o nā ʻōnaehana hoʻolaha a me ke kīwī, nā lako e hoʻoponopono i ka ikaika o ka hōʻailona e kūlike me ka hana hōʻailona i hoʻolaha ʻia a hoʻonui i ka laulā hōʻailona.
4. I loko o nā antenna kīwī, hoʻohana ʻia e kaulike i ka mana hōʻailona ma waena o nā amplifiers a me nā antennas.
QualwaveHāʻawi i nā ʻano attenuators coaxial 75 ohms kiʻekiʻe a me ka mana kiʻekiʻe e uhi ana i ka alapine (frequency) DC ~ 3GHz, hiki ke hoʻohālikelike ʻia me nā mea hoʻohui BNC, F-type, a me N-type. ʻO ka attenuation ma waena o 1 a 40dB. ʻO nā attenuators me ka pololei kiʻekiʻe a me ka mana kiʻekiʻe, ka hilinaʻi maikaʻi, ʻo ka hapa nui o nā huahana he ROHS compliant, hiki ke hoʻokō i nā pono like ʻole o nā mea kūʻai aku.
