28-31GHz Waveguide Harmonic Bandstop kānana

Nā hiʻohiʻona

ʻO kāna kānana Passive, ʻike ʻia hoʻi 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 ka hoʻohana ʻana 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 ka 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 resonates ʻelua i ka moʻo he 0, ka mea i ʻike maʻamau ʻia ʻo ka loop impedance haʻahaʻa, i kēia manawa, e kahe ka harmonic 5 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 kiʻekiʻe, a hiki ke hoʻopaʻa i nā hōʻailona pono ʻole a me ka walaʻau ma waho o ke alapine.

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 i ka hoʻokumu ʻana o ka pūpū, inā ʻaʻole ia e hoʻopilikia i ka waho o ka band suppression a me ka papa kuhikuhi papa.
