He hononga hiko te hononga pūihi e whakamahia ana hei hono i ngā taputapu auau reo irirangi me ngā taura. Ko tana mahi matua he tuku tohu auau teitei.
He tino pai ngā āhuatanga taurite ārai o te hononga, e whakarite ana kia whakaitihia te whakaata me te ngaronga o te tohu i te wā e tukuna ana i waenga i te hononga me te taura. He pai ngā āhuatanga parepare hei ārai i te pānga o te pokanoa hikohiko o waho ki te kounga o te tohu.
Ko ngā momo hononga pūihi noa ko te SMA, te BNC, te momo-N, te TNC, me ētahi atu, e tika ana mō ngā whakaritenga tono rerekē.
Ka whakamōhio atu hoki tēnei tuhinga ki a koe ki ētahi hononga e whakamahia whānuitia ana:
Auautanga whakamahinga hononga
Hononga SMA
Ko te hononga honohono RF momo SMA he hononga RF/ngaruiti i hangaia e Bendix me Omni-Spectra i te mutunga o te tekau tau atu i 1950. Ko tētahi o ngā hononga i whakamahia whānuitia i taua wā.
I te tīmatanga, i whakamahia ngā hononga SMA ki ngā taura coaxial āhua-pakari 0.141″, e whakamahia ana i roto i ngā tono ngaruiti i roto i te umanga hōia, me te whakakī hiko Teflon.
Nā te mea he iti te rahi o te hononga SMA, ā, ka taea te mahi i ngā auau teitei ake (ko te awhe auau mai i te DC ki te 18GHz ina honoa ki ngā taura āhua-mārō, me te DC ki te 12.4GHz ina honoa ki ngā taura ngāwari), kei te tere haere te rongonui. Inaianei ka taea e ētahi kamupene te whakaputa hononga SMA tata ki te DC ~ 27GHz. Ahakoa te whanaketanga o ngā hononga ngaru mirimita (pēnei i te 3.5mm, 2.92mm) e whakaaro ana ki te hototahi ā-ringa ki ngā hononga SMA.
Hononga SMA
Hononga BNC
Ko te ingoa katoa o te hononga BNC ko Bayonet Nut Connector (he hononga snap-fit, e whakaahua mārama ana tēnei ingoa i te āhua o tēnei hononga), i tapaina i muri i tana tikanga raka whakairi bayonet me ōna kaihanga a Paul Neill rāua ko Carl Concelman.
he hononga RF noa e whakaiti ana i te whakaata/ngaronga ngaru. Ko ngā hononga BNC e whakamahia whānuitia ana i roto i ngā tono auau-iti ki te auau-waenga, ā, e whakamahia whānuitia ana i roto i ngā pūnaha whakawhitiwhiti ahokore, ngā pouaka whakaata, ngā taputapu whakamātautau, me ngā taputapu hiko RF.
I whakamahia anō hoki ngā hononga BNC i ngā whatunga rorohiko o mua. Ka tautoko te hononga BNC i ngā auau tohu mai i te 0 ki te 4GHz, engari ka taea hoki te mahi tae atu ki te 12GHz mēnā ka whakamahia he putanga kounga teitei motuhake i hangaia mō tēnei auau. E rua ngā momo ārai āhuatanga, arā, 50 ohms me 75 ohms. He rongonui ake ngā hononga BNC 50 ohm.
Hononga momo N
I hangaia te hononga pūihi momo-N e Paul Neal i Bell Labs i ngā tau 1940. I hangaia tuatahitia ngā hononga momo-N hei whakatutuki i ngā hiahia o ngā hōia me ngā mara rererangi mō te hono i ngā pūnaha radar me ētahi atu taputapu auau reo irirangi. Kua hangaia te hononga momo-N me te hononga miro, e whakarato ana i te taurite aukati me te mahi tiaki pai, ā, he pai mō ngā tono mana teitei me te auau iti.
Ko te whānuitanga auau o ngā hononga Momo N e whakawhirinaki ana ki ngā paerewa hoahoa me te hanga motuhake. I te nuinga o te wā, ka taea e ngā hononga momo-N te hipoki i te whānuitanga auau mai i te 0 Hz (DC) ki te 11 GHz ki te 18 GHz. Heoi, ka taea e ngā hononga momo-N kounga teitei te tautoko i ngā whānuitanga auau teitei ake, tae atu ki te 18 GHz. I roto i ngā tono mahi, ka whakamahia te nuinga o ngā hononga momo-N i roto i ngā tono auau iti ki te waenga, pērā i te whakawhitiwhiti kōrero ahokore, te pāpāho, te whakawhitiwhiti kōrero amiorangi me ngā pūnaha radar.
Hononga momo N
Hononga TNC
I hangaia ngātahitia te hononga TNC (Threaded Neill-Concelman) e Paul Neill rāua ko Carl Concelman i ngā tau tōmua o te tekau tau atu i 1960. He putanga whakapai ake tēnei o te hononga BNC, ā, e whakamahi ana i te tikanga hononga miro.
Ko te ātete āhuatanga he 50 ohms, ā, ko te awhe auau mahi tino pai ko te 0-11GHz. I roto i te awhe auau ngaruiti, he pai ake te mahi a ngā hononga TNC i ngā hononga BNC. He āhuatanga o te ātete ru kaha, te pono teitei, te pai o ngā āhuatanga miihini me te hiko, me ētahi atu, ā, he whānuitia te whakamahinga i roto i ngā taputapu reo irirangi me ngā taputapu hiko hei hono i ngā taura coaxial RF.
Hononga 3.5mm
He hononga honohono auau reo irirangi te hononga 3.5mm. Ko te diameter o roto o te ara iahiko o waho he 3.5mm, ko te aukati āhuatanga he 50Ω, ā, ko te tikanga hononga he miro 1/4-36UNS-2 inihi.
I waenganui o te tekau tau atu i 1970, i whakarewahia e ngā kamupene o Amerika, a Hewlett-Packard me Amphenol (nā te Kamupene HP i whakawhanake te nuinga, ā, nā te Kamupene Amphenol i whakahaere te hanga i ngā wā tōmua) he hononga 3.5mm, he auau mahi tae atu ki te 33GHz, ā, koinei te auau reo irirangi tuatahi ka taea te whakamahi i roto i te roopu ngaru mirimita. Ko tētahi o ngā hononga coaxial.
Ki te whakatauritea ki ngā hononga SMA (tae atu ki te "Super SMA" a Southwest Microwave), ka whakamahia e ngā hononga 3.5mm te hau-whakakore, he matotoru ake ngā kaiārahi o waho i ngā hononga SMA, ā, he kaha ake te miihini. Nō reira, ehara i te mea ko te mahi hiko anake te mea pai ake i ngā hononga SMA, engari ko te roa o te mahi miihini me te kaha ki te whakahoki i ngā mahi he teitei ake i ngā hononga SMA, ā, he pai ake mō te whakamahi i roto i te umanga whakamātautau.
Hononga 2.92mm
Ko te hononga 2.92mm, e kiia ana e ētahi kaihanga ko te hononga 2.9mm, te hononga momo-K rānei, ā, e kiia ana e ētahi kaihanga ko te hononga SMK, KMC, WMP4, me ētahi atu, he hononga coaxial auau reo irirangi me te diameter o roto o te ara iahiko o waho ko te 2.92mm. Ngā Āhuatanga Ko te aukati he 50Ω, ā, ko te tikanga hononga he miro 1/4-36UNS-2 inihi. He rite tōna hanganga ki te hononga 3.5mm, he iti ake noa iho.
I te tau 1983, i whakawhanakehia e te miihini matua o Wiltron, a William.Old.Field, tētahi hononga hou 2.92mm/K i runga i te whakarāpopototanga me te whakakore i ngā hononga ngaru mirimita i whakaurua i mua (ko te hononga momo-K te tohu hokohoko). Ko te diameter o roto o tēnei hononga he 1.27mm, ā, ka taea te hono atu ki ngā hononga SMA me ngā hononga 3.5mm.
He tino pai te mahi hiko o te hononga 2.92mm i roto i te awhe auau (0-46) GHz, ā, he hototahi ā-ringa ki ngā hononga SMA me ngā hononga 3.5mm. Nō reira, i tere tonu te noho hei tētahi o ngā hononga mmWave e whakamahia whānuitia ana.
Hononga 2.4mm
I whakahaerehia ngātahitia te whanaketanga o te hononga 2.4mm e HP (te mua o Keysight Technologies), Amphenol me M/A-COM. Ka taea te whakaaro he putanga iti ake o te hononga 3.5mm, nō reira he nui te pikinga o te auau mōrahi. He whānuitia te whakamahinga o tēnei hononga i roto i ngā pūnaha 50GHz, ā, ka taea te mahi tae atu ki te 60GHz. Hei whakaoti i te raruraru e ngāwari ana te pakaru o ngā hononga SMA me te 2.92mm, kua hangaia te hononga 2.4mm hei whakakore i ēnei ngoikoretanga mā te whakanui ake i te matotoru o te pakitara o waho o te hononga me te whakapakari i ngā pine uwha. Mā tēnei hoahoa auaha ka taea e te hononga 2.4mm te mahi pai i roto i ngā tono auau teitei.
Kua whanake te whanaketanga o ngā hononga pūihi mai i ngā hoahoa miro māmā ki ngā momo hononga mahi-teitei. I te whanaketanga o te hangarau, kei te whai tonu ngā hononga i ngā āhuatanga o te rahi iti ake, te auau teitei ake me te whānui whānui hei whakatutuki i ngā hiahia hurihuri o te whakawhitiwhiti ahokore. He āhuatanga me ngā painga motuhake tō ia hononga i roto i ngā horopaki tono rerekē, nō reira he mea tino nui te whiriwhiri i te hononga pūihi tika hei whakarite i te kounga me te pumau o te tuku tohu.
