28-31GHz Waveguide Harmonic Bandstop kānana

ʻO ka wehewehe pōkole:

ʻO ka kānana Waveguide kahi ʻano kānana laina hoʻouna.ʻO ka maʻamau, ua haku ʻia ka kānana waveguide me nā mea hoʻopau a me nā ʻāpana laina hoʻouna.Hiki i nā mea ʻelua ke like me nā mea hoʻohālikelike lumped pili a me nā kaʻa, nā hawewe alakaʻi e hāʻawi i ka reactance like, nā ʻāpana laina hoʻouna, nā resonator like a pēlā aku.

I ka hoʻolālā ʻana i ka kānana, pono mākou e noʻonoʻo piha i ka hoʻohana maoli ʻana o ka mea kūʻai aku, nā koi o ka mea kūʻai aku (e like me ka leo kānana, nalowale, ma waho o ka band frequency, suppression system a me ka mana mana) a me ka ʻenehana hana e hoʻokō i ka hopena premium o ka kānana. .

ʻO kāna kānana Passive, ʻike ʻia ʻo LC kānana, he kānana kānana i haku ʻia me ka hui pū ʻana o ka inductance, capacitance a me ke kūpaʻa, hiki ke kānana i hoʻokahi a ʻoi aku paha nā harmonics.ʻO ka mea maʻamau a maʻalahi hoʻi e hoʻohana i ka ʻōnaehana kānana passive ʻo ia ka hoʻopili ʻana i ka inductance a me ka capacitance i ka moʻo, hiki ke hana i kahi bypass impedance haʻahaʻa no nā harmonics nui (3, 5 a me 7);ʻO ke kānana hoʻokahi, ka kānana pālua a me ka kānana ala kiʻekiʻe he mau kānana passive.

Hoʻokumu ʻia ka kānana passive me ka reactance string capacitor.

E like me ke kūlana harmonic o ka ʻōnaehana, no ka laʻana, aia ka 5th harmonics, a ʻo ke alapine harmonic ʻo 250Hz.

I kēia manawa, hoʻohālikelike ʻia ka capacitance a me ka reactance o ka kānana passive, a kani lākou i ke alapine o 250Hz.No ka mea, ʻo ka nui o ka impedance o nā mea ʻelua i ka moʻo he 0, ka mea i ʻike maʻamau ʻia ʻo ka loop impedance haʻahaʻa, i kēia manawa, e kahe ka 5th harmonic a pau i ka kānana passive e hoʻokō i ka hopena kānana.

Ma muli o ke kaʻina hana, ʻōlelo maʻamau, hiki i ka kānana passive ke hoʻokō ma kahi o 245-250Hz, a hiki i ka hopena kānana ke piʻi ma mua o 80%.

Loaʻa iā ia nā koho alapine maikaʻi a me nā hana kānana i nā kaapuni a me nā ʻōnaehana uila uila kiʻekiʻe, a hiki ke hoʻopau i nā hōʻailona pono ʻole a me ka walaʻau ma waho o ka band frequency.

Hoʻohana ʻia ia no ka mokulele, aerospace, radar, kamaʻilio, countermeasure uila, lekiō a me ke kīwī a me nā mea hoʻāʻo uila like ʻole.

I ka hoʻohana ʻana, e hoʻolohe pono i ka hoʻokumu ʻana o ka pūpū, i ʻole e hoʻopilikia i ka hoʻopau ʻana o ka band a me ka papa kuhikuhi.
