RF High Power BroadBand Nā ʻōnaehana hoʻāʻo 75 ohms Attenuators
ʻO kahi attenuator 75 ohm kahi ʻano o ka attenuator i kapa ʻia no kona impedance o 75 ohms.
He ʻāpana passive i hoʻohana ʻia no ka hoʻoponopono ʻana i ka ikaika hōʻailona o kahi kaapuni, ʻo kahi attenuator 75 ohm e pale i ka hoʻonui nui ʻana a me ka distortion o ka hōʻailona, a pale i ka hana ʻole ʻia e ka overload hōʻailona.
ʻO kāna mau hiʻohiʻona nui:
1. Hoʻohālikelike impedance: ʻO ka 75 ohm hiʻohiʻona impedance pili i ke ʻano impedance o ka laina hoʻouna hōʻailona o nā mea wikiō, hoʻolaha kīwī a me nā ʻōnaehana kelepona, pēlā e hōʻemi ai i ka noʻonoʻo a me ka nalowale o ka hōʻailona hoʻouna.
2. Haʻahaʻa haʻahaʻa: Hiki i ka attenuator ke hoʻemi i ka ikaika o ka hōʻailona me ka ʻole o ka hoʻokomo ʻana i ka distortion hou a i ʻole ka hōʻailona hōʻailona.
3. ʻO ka hilinaʻi kiʻekiʻe: Ma muli o ka nui o nā attenuators i nā ʻāpana passive a ʻaʻohe ʻāpana neʻe, hilinaʻi nui lākou a ʻaʻole koi i ka mālama ʻana a i ʻole ke pani.
Hoʻohana pinepine ʻia nā attenuators 75 ohm i kēia mau noi:
1. I loko o nā ʻupena kīwī kelepona a me nā ʻupena kīwī kikohoʻe, hoʻohana ʻia ia e hoʻoponopono i ka ikaika o ka hōʻailona a hoʻemi i ka noʻonoʻo ʻana a me ka nalowale.
2. I ka wā o ka hana ʻana a me ka hoʻouna ʻana i nā wikiō kiʻekiʻe a me ka wehewehe kiʻekiʻe, e kāohi i ka ikaika o ka hōʻailona a mālama i ka maikaʻi hoʻololi.
3. Ma nā ʻōnaehana hoʻolaha hoʻolaha a me ke kīwī, nā mea hana e hoʻoponopono ai i ka ikaika hōʻailona e kūlike i ka hoʻoili ʻana i nā hōʻailona kikoʻī a hoʻonui i ka laulā hōʻailona.
4. I nā antenna kīwī, hoʻohana ʻia e kaulike i ka mana hōʻailona ma waena o nā amplifiers a me nā antennas.
Kaʻaleʻaleʻahoʻolako i nā ʻano kiʻekiʻe kiʻekiʻe a me ka mana kiʻekiʻe coaxial 75 ohms attenuators uhi i ka laina alapine DC ~ 3GHz, hiki ke hoʻohālikelike ʻia me nā mea hoʻohui BNC, F-type, a me N-type. ʻO ka nui o ka attenuation mai 1 a 40dB. ʻO nā attenuators me ke kiʻekiʻe kiʻekiʻe a me ka mana kiʻekiʻe, ka maikaʻi hilinaʻi, ʻo ka hapa nui o nā huahana he ROHS compliant, hiki ke hoʻokō i nā pono like ʻole o nā mea kūʻai.
