LC kānana hiʻohiʻona

Kānana Bandpass pololei
Hoʻohana ka 4500-5900MHz LC Filter i ka hoʻolālā ʻoihana LC (inductor-capacitor) kiʻekiʻe e hana i kahi pihi pane alapine ʻoi. Hāʻawi kēia ʻano bandpass pololei i nā hōʻailona i loko o ka laulā 4500-5900MHz e hele me ka liʻiliʻi o ka attenuation ʻoiai ke kāohi pono nei i nā alapine ma waho o kēia hui. Loaʻa ka kānana i nā hiʻohiʻona ʻoi loa (ʻoi aku ma mua o ka hōʻole ʻana o 40dB ma ± 100MHz offset), e hana ana i kahi "window" pale e pale ai i ka hoʻopili ʻana i ke kahawai pili.

Hoʻohui Mea Kiʻekiʻe-Q
Ma ka hoʻohana ʻana i nā ʻāpana kumu kiʻekiʻe (Q), hoʻemi ka LC Filter i ka nalowale hoʻokomo ʻana i loko o ka passband me ka hoʻonui ʻana i ka hōʻole ʻana i waho. ʻO nā inductors Q kiʻekiʻe a me nā capacitors e hōʻemi i ka hoʻoheheʻe ʻana o ka ikehu, e mālama ana i ka pono o ka hōʻailona ʻoiai ke kāohi nei i nā alapine makemake ʻole. ʻO kēia pōmaikaʻi ʻelua e hōʻoia i ka ikaika o nā hōʻailona makemake ʻoiai e hoʻemi nui ʻia nā kumu hoʻopilikia.

Hoʻolālā Palekana Electromagnetic
Hoʻokomo ʻia ka hale paʻa o ka kānana LC i ka pale electromagnetic e pale ai i ka walaʻau RF waho mai ka hui ʻana i ke ala hōʻailona. ʻO kēia pale, i hui pū ʻia me ke koho alapine maʻamau o ka pūnaewele LC, hana i kahi pale ʻelua ʻāpana i ke keʻakeʻa - ʻo ka mua ma ke kāohi ʻana i ka walaʻau waho a me ka lua ma ke kānana ʻana i nā alapine i makemake ʻole ʻia.

Impedance Matching Optimization
Hoʻohālikelike impedance pololei (maʻamau 50Ω) a puni kaLC kānanaHo'emi ka ho'olālā 'ana i nā hō'ailona no'ono'o e hiki ai ke ho'ololi i ka intermodulation. Ma ka mālama ʻana i nā hiʻohiʻona impedance mau, pale ka LC Filter i ka hana ʻana i nā huahana interference hou i loko o ka ʻōnaehana kamaʻilio, mālama i ka maʻemaʻe hōʻailona.

ʻO ke kūpaʻa wela a me ka mīkini
ʻO ka hana paʻa o ka kānana LC e hōʻoia i ka hana maʻamau ma waena o nā ʻano wela (-40°C a +85°C) a me nā koʻikoʻi mechanical. Mālama kēia kūpaʻa i ka neʻe pinepine ʻana i hiki ke ʻae i ke komo ʻana i ka passband, e mālama ana i ka hoʻopaʻa paʻa pono i nā kaiapuni hana like ʻole.

Nā pono hale hana

ʻO Si Chuan Keenlion Microwave kahi koho nui ma nā ʻāpana haiki a me ka laulā ākea, e uhi ana i nā alapine mai 0.5 a 50 GHz. Hoʻolālā ʻia lākou e lawelawe mai ka 10 a 30 watts mana hoʻokomo i loko o kahi ʻōnaehana hoʻouna 50-ohm. Hoʻohana ʻia nā hoʻolālā Microstrip a i ʻole stripline, a hoʻopaʻa ʻia no ka hana maikaʻi loa.
