Whakaahuatanga Hua
1. Whakarāpopototanga o te Hua
SA1300CKo te whakakaha pūmau o waho e rua ngā ahunga o te raupapa whakakaha pūmau teitei hou kua whakawhanakehia. He hoahoa ara iahiko pakari, kua arotauhia, he tukanga ā-roto pūtaiao, he whaitake hoki, me ngā rauemi kounga teitei, e whakarite ana i te whakakaha pumau me te iti o te hē. Koinei te kōwhiringa pai rawa atu mō te hanga whatunga tuku CATV rua-ahu nui, rahi waenga rānei.
2. Ngā Āhuatanga Mahi
- Ko te ara whakamua o mua ka tango i te waeine whakakaha pana-tōia haruru iti taupū teitei hou kua kawemaihia, te waeine pana-tōia GaAs rānei, ka tango te waeine putanga i te mana takirua taupū teitei hou kua kawemaihia.ymōrahi whakakaha, mōrahi whakakaha GaAs rānei. He pai te taupū kore-raina, ā, he pumau ake te taumata putanga. Ka whakamahia e te ara whakahoki te mōrahi whakakaha whakahoki motuhake taupū teitei hou kua kawemaihia. He iti te hē, ā, he teitei te ōwehenga tohu ki te haruru.
- He māmā ake te patuiro nā te tātari takirua mono-roto, te whakataurite me te whakaiti mono-roto kua whakaritea (kua taea te whakarite rānei), me ngā tauranga kimi ipurangi pūtaiao me te whaitake.
- Ka taea e ngā taputapu te mahi tonu mō te wā roa i raro i ngā āhuatanga taiao kino o waho. Nā te whare ārai wai konumohe, te pono o te pūtake hiko whakawhiti, me te pūnaha ārai uira tino pakari.
- Ka whakamahia e te anga te hoahoa modular kua whakauruhia; he watea te tiaki taputapu, te whakakapinga, me te patuiro.
3. Aratohu Tono
Whakaū mai: te auau wehewehe hononga-ake me te hononga-iho o ngā ara e rua-ahu.
4. Ngā Tohutohu Motuhake:
- I mua i te whakamahinga o te hua, me whakapūmau te whenua!
- Ko te kaha o te iahiko mōrahi o te hua he 10A.
