ʻO ka microstrip attenuator kahi ʻano attenuation chip. ʻO ka mea i kapa ʻia ʻo "spin on" he ʻano hoʻonohonoho. No ka hoʻohana ʻana i kēia ʻano attenuation chip, pono kahi uhi ea poepoe a huinahā paha, aia ma nā ʻaoʻao ʻelua o ka substrate.
Pono e hoʻopaʻa ʻia nā papa kālā ʻelua ma nā ʻaoʻao ʻelua o ke substrate ma ke kuhikuhi lōʻihi.
I ka wā e hoʻohana ai, hiki i kā mākou hui ke hāʻawi i nā mea kūʻai aku me nā uhi ea o nā nui like ʻole a me nā alapine (frequency) no ka manuahi.
Hiki i nā mea hoʻohana ke hana i nā lima e like me ka nui o ka uhi ea, a ʻoi aku ka laulā o ke kahawai honua o ka lima ma mua o ka mānoanoa o ka substrate.
A laila, ua kāʻei ʻia kahi lihi elastic conductive a puni nā ʻaoʻao ʻelua o ka substrate a hoʻokomo ʻia i loko o ka lima.
Hoʻohālikelike ʻia ka ʻaoʻao o waho o ka lima me kahi poho wela e kūlike ana i ka mana.
Hoʻopili ʻia nā mea hoʻohui ma nā ʻaoʻao ʻelua i ka lua me nā kaula, a ʻo ka pilina ma waena o ka mea hoʻohui a me ka pā attenuation microstrip wili e hana ʻia me kahi pine elastic, kahi e pili ana i ka elastic me ka ʻaoʻao ʻaoʻao o ka pā attenuation.
ʻO ka attenuator microstrip Rotary ka huahana me nā ʻano alapine kiʻekiʻe loa ma waena o nā ʻāpana āpau, a ʻo ia ke koho mua no ka hana ʻana i nā attenuator alapine kiʻekiʻe.
ʻO ke kumu hana o ka microstrip attenuator e pili ana i ke ʻano kino o ka attenuation signal. Hoʻonāwaliwali ia i nā hōʻailona microwave i ka wā o ka hoʻouna ʻana i loko o ka chip ma ke koho ʻana i nā mea kūpono a me ka hoʻolālā ʻana i nā ʻano. Ma ke ʻano laulā, hoʻohana nā chips attenuation i nā ʻano e like me ka absorption, scattering, a i ʻole reflection e hoʻokō ai i ka attenuation. Hiki i kēia mau mīkini ke hoʻomalu i ka attenuation a me ka pane alapine ma ka hoʻoponopono ʻana i nā palena o ka mea chip a me ke ʻano.
ʻO ka ʻano o nā attenuators microstrip i hana pinepine ʻia me nā laina hoʻoili microwave a me nā pūnaewele hoʻohālikelike impedance. ʻO nā laina hoʻoili microwave nā kahawai no ka hoʻoili hōʻailona, a pono e noʻonoʻo ʻia nā mea e like me ka nalowale o ka hoʻoili a me ka nalowale hoʻi i ka hoʻolālā. Hoʻohana ʻia ka pūnaewele hoʻohālikelike impedance e hōʻoia i ka hoʻemi piha ʻana o ka hōʻailona, e hāʻawi ana i ka nui o ka attenuation pololei.
ʻO ka nui o ka attenuation o ka microstrip attenuator a mākou e hāʻawi nei he paʻa a mau, a he kūpaʻa a hilinaʻi hoʻi, hiki ke hoʻohana ʻia i nā kūlana kahi i pono ʻole ai ka hoʻoponopono pinepine. Hoʻohana nui ʻia nā attenuators paʻa i nā ʻōnaehana e like me ka radar, ke kamaʻilio ukali, a me ke ana ʻana o ka microwave.
