Ngā Pūwhakawhiti Poraka (LNB)

I roto i ngā pūnaha whakawhitiwhiti kōrero, hei whakahaere i te tuku tohu me te whakatutuki i te whakamahinga anō o te hongere, he tino teitei te auau o ngā tohu e tukuna ana, nō reira he wāhanga nui o te rangahau pūnaha whakawhitiwhiti kōrero te huringa auau o ngā tohu. E ai ki te āhuatanga i mua me muri i te huringa auau, ka taea te wehewehe ki te huringa whakararo (whakaiti auau) me te huringa whakarunga (whakapiki auau).
I roto i te kaiwhiwhi, mēnā he iti iho te tohu auau waenga i whiwhihia i muri i te whakaranu i te tohu taketake, ka kiia tēnei tikanga whakaranu he block downconverters (LNB).
Ko te tikanga o ngā pūtahuri poraka he whakarea i te tohu i whiwhihia ki te tohu orooro ā-rohe i hangaia e te orooro ā-rohe, kātahi ka whiwhi i te tohu kua hurihia mā te tātari pāheke-iti. Ka taea te wehewehe i ngā tohu e rua kua whakareatia ki te whakaranu tūturu me te whakaranu matatini mā te whakaaturanga tūturu, matatini rānei.
Ko te kaupapa o ngā pūwhakaheke poraka he whakaiti i te auau kawe o te tohu, he tango tika rānei i te auau kawe hei whiwhi i te tohu turanga. Nā te ngāwari o te ara iahiko me te iti o te utu, e whakamahia whānuitia ana te tikanga whakaheke i roto i ngā taputapu ā-iwi me ngā taputapu hōia he iti ngā whakaritenga mahi.

Taupānga:

1. Pouaka Whakaata Amiorangi: He wāhanga matua ngā LNB i roto i ngā pūnaha whiwhinga pouaka whakaata amiorangi. Ka tāutahia ēnei ki te pūwāhi arotahi o te pūihi amiorangi (paraboloid, rihi rānei), ka whiwhi i te tohu pouaka whakaata e tukuna ana e te amiorangi, ā, ka hurihia hei tohu auau waenga ka taea te tukatuka e te kaiwhiwhi.
2. Ipurangi Amiorangi: I roto i ngā pūnaha Ipurangi Amiorangi, ka whakamahia ngā whakakaha reo hei whiwhi raraunga Ipurangi e tukuna ana mai i ngā amiorangi. Ka whiwhi ngā taputapu kaiwhakamahi i ngā raraunga mā te LNB, ka wetewetehia, ka tukatukahia mā te pouwhanga.
3. Whakawhitiwhiti Kōrero Amiorangi: E whakamahia whānuitia ana ngā whakakaha RF i roto i ngā pūnaha whakawhitiwhiti kōrero amiorangi, tae atu ki ngā waea amiorangi, ngā pāhotanga amiorangi, te tuku raraunga amiorangi, me ētahi atu. Ka āwhina ēnei ki te whiwhi me te tukatuka i ngā momo tohu whakawhitiwhiti kōrero e tukuna ana mai i ngā amiorangi.
4. Te Tirotiro Whenua me te Pūrongo Mamao: I roto i ētahi tono tirotiro Whenua me te pūrongo mamao, ka whakamahia ngā whakakaha ngaruiti hei whiwhi raraunga pūrongo mamao e tukuna ana mai i ngā amiorangi. Ka taea te whakamahi i ēnei raraunga i roto i te aroturuki huarere, te aroturuki taiao, te whakatūpato āwhati me ētahi atu mara.
Hei whakarāpopototanga, he mea nui te tūranga o ngā LNB i roto i ngā pūnaha whakawhitiwhiti amiorangi o ēnei rā, ā, e whakamahia whānuitia ana i roto i te pāpāho pouaka whakaata, te urunga Ipurangi, ngā whakawhitiwhiti raraunga me ngā momo mara ngaio.

QualwaveE whakarato ana i ngā momo LNB rerekē i roto i te S~Ka-Band, me te pāmahana haruru o te 45~240K. He rerekē ngā momo o ngā pito hei whakatutuki i ngā hiahia o ngā kiritaki.
