ʻO ka Attenuator kahi mea uila i hoʻohana nui ʻia i nā lako uila, a ʻo kāna hana nui ka hāʻawi ʻana i ka attenuation.He mea hoʻohana ia i ka ikehu, e huli ana i ka wela ma hope o ka hoʻohana ʻana i ka mana.ʻO kāna mau kumu nui: (1) Hoʻoponopono i ka nui o ka hōʻailona ma ke kaapuni;(2) I ke kaapuni ana i ke kaapuni ana, hiki ke hoohana ia e heluhelu pololei i ka waiwai attenuation o ka pūnaewele i hoao;(3) E hoʻomaikaʻi i ka hoʻohālikelike ʻana i ka impedance, inā makemake kekahi mau kaapuni Ke hoʻohana ʻia kahi impedance haʻahaʻa paʻa, hiki ke hoʻokomo ʻia kahi attenuator ma waena o ke kaapuni a me ka impedance ukana maoli e pale i ka hoʻololi impedance.No laila i ka hoʻohana ʻana i ka attenuator, he aha nā mea e pono ai ke nānā?
E hoʻolauna mākou iā ia ma lalo nei:
1. Ka pane alapine: ka bandwidth alapine, hōʻike maʻamau i ka megahertz (MHz) a i ʻole gigahertz (GHz).Loaʻa i nā attenuators kumu nui ka bandwidth ma kahi o 5 GHz, me ka bandwidth kiʻekiʻe o 50 GHz.
2. Attenuation laulā a me ka hoʻolālā:
E pili ana ka pae hoʻohaʻahaʻa i ka ratio attenuation, maʻamau mai 3dB, 10dB, 14dB, 20dB, a hiki i 110dB.ʻO ke ʻano o ka attenuation: 10lg (input/output), no ka laʻana: 10dB characterization: input: output = attenuation lehulehu = 10 manawa.Hoʻokaʻawale ʻia ke ʻano i ʻelua mau ʻano: paʻa paʻa atenuator a me step proportional adjustable attenuator.ʻO kahi attenuator paʻa e pili ana i kahi attenuator me kahi lākiō paʻa mau i loko o kekahi mau alapine.ʻO kahi Step attenuator kahi attenuator me kahi waiwai paʻa a me ka lakene hiki ke hoʻololi ʻia.Hoʻokaʻawale ʻia i loko o ka manual step attenuator a me programmable step attenuator.
3. ʻO ke poʻo o ka pilina a me ka nui o ka pilina:
Hoʻokaʻawale ʻia ke ʻano hoʻohui i ke ʻano BNC, ʻano N, ʻano TNC, ʻano SMA, ʻano SMC, a me nā mea ʻē aʻe.
Hoʻokaʻawale ʻia ka nui pili i nā ʻōnaehana metric a me imperial, a ua hoʻoholo ʻia ka mea i luna e like me nā koi o ka hoʻohana ʻana;inā pono e hoʻopili ʻia nā ʻano mea hoʻopili, hiki ke hoʻolako ʻia nā mea hoʻopili pili pili, no ka laʻana: BNC i ka mea hoʻohui N-type, etc.
4. Attenuation index:
He nui nā koi o nā hōʻailona attenuation, ʻoi aku ka nui o nā ʻano aʻe: ka pololei o ka attenuation, ke kūpaʻa i ka mana, ka impedance hiʻohiʻona, ka hilinaʻi, ka hana hou, etc.
E like me ka mea hoʻolālā oattenuators, Hiki iā Jingxin ke kākoʻo iā ʻoe me nā ʻano attenuators like ʻole e like me kāu hoʻonā RF.
