Whakaahuahia pototia ngā tawhā mahi o ngā whakawehe RF

I roto i ngā pūnaha RF, ko te mahi matua oNgā wehewehe RFKo te whakarato, ko te whakarei ake rānei i ngā āheinga wehewehe mō ngā ara tohu rerekē. He porowhita kua whakapaitia, ka mutu mā te whakataurite i te aukati i tētahi o ōna tauranga. He mea whakamahi i roto i ngā pūnaha radar hei tiaki i ngā ara iahiko tairongo i te pito whiwhi kia kore ai e pokanoa mai i ngā tohu tuku mana-teitei, kia tutuki ai te wehewehe whai hua o ngā tohu tuku me ngā tohu whiwhi. Mā tēnei tuhinga koe e ārahi ki te mārama ki ngā tawhā mahi matua oNgā wehewehe RF.

一. Whakamaramatanga
Ngā wehewehe RFhe momo motuhake tonu oNgā porowhita RF, e whakamutua ana tētahi tauranga (ko te pito ara whakamuri o te mekameka tohu te tikanga) e tētahi kawenga ōrite hei whakatutuki i te tuku tohu kotahi-angi. Ka tukuna noa e ia ngā tohu kia haere i tētahi ahunga kua whakaritea i mua i te wā, me te pehi i ngā whakaata, te haruru, ngā tohu pokanoa rānei mai i te ahunga whakamuri, kia tutuki ai te wehenga whai hua o te hononga o mua.

Ngā wehewehe RF or ngā kaitahuri hikohe taputapu ferrite kore mahi te nuinga o te wā e ārahi ana i ngā ngaru hikohiko mai i te pito tāuru i tētahi ahunga motuhake mā roto i tētahi whirihoranga papa aukume motuhake, ā, ka puta ki te tauranga tata.

Ki te whakataurite ki ngā mea wehewehe kua whakarerekētia mai i te tikangaNgā porowhita RF, ko ngā taputapu i hangaia mō ngā kaupapa wehe he iti ake te rahi, he māmā ake hoki te whakauru. Ko te kounga o te taurite o te pito ka pāngia tika e tōna mahi wehe.

Whakawehenga paerewa auau teitei, Wehenga (12-14dB), 18 ki te 40GHz

Ngā tawhā mahi
Ngā tohu mahi matua oNgā wehewehe RFwhakauru:

Awhe auau (Hz)

Āraitanga (Ω)

Ngaronga whakaurunga (dB)

Wehewehenga (dB)

Te ōwehenga ngaru tū ngaohiko (VSWR)

Te kaha whakahaere mana whakamua (ngaru tonu, tihi rānei)

Te kaha whakahaere mana whakamuri (ngaru tonu, tihi rānei)

Momo hononga

I roto i ēnei, ko te wehewehe tētahi o ngā tawhā tino nui, e tohu ana i te nui o te hononga i waenga i ngā ara RF i roto i ngā decibels (dB). Ko te teitei ake o te uara, ko te iti ake o te hononga i waenga i ngā tohu, ā, ko te pai ake o te pānga wehewehe. Nā te mea he whānui te hononga hikohiko i roto i ngā ara kawe hiko katoa, he mea tino nui kia mau tonu te wehewehe teitei i waenga i ngā ara i roto i ngā pūnaha whakawhitiwhiti kōrero, i ngā pūnaha pūoko rānei.

Hei tāpiritanga, kia rite ki ngā whakaritenga tono rerekē,ngā kaiwhakaweheme whai kaha whakahaere mana e tika ana, he iti te VSWR, he hanganga hononga pono-teitei, he rahi e tika ana, me te awhe pāmahana whakahaere e taea ai te urutau, ka pā pea ki tā rātou mahi i roto i ngā horopaki tūturu. Tērā pea ka whakawhāitihia te taupū mana mōrahi o te wehewehe e ngā āhuatanga o te kawenga kua mutu.
