He momo taputapu tukatuka tohu nui ngā hononga ahunga. Ko tā rātou mahi matua he tauira i ngā tohu RF i te taumata hononga kua whakaritea, me te wehenga teitei i waenga i ngā tauranga tohu me ngā tauranga kua tauirahia — e tautoko ana i te tātari, te ine me te tukatuka mō ngā tono maha. Nā te mea he taputapu kore mahi, ka mahi anō hoki rātou i te ahunga whakamuri, me ngā tohu e werohia ana ki te ara matua e ai ki te ahunga me te taumata hononga o ngā taputapu. He iti noa ngā rerekētanga o te whirihoranga o ngā hononga ahunga, ka kite tātou i raro nei.
Ngā Whakamāramatanga
Ko te mea tino pai, he hononga kore-ngaro, he hononga ōrite, he hononga tauutuutu hoki te hononga. Ko ngā āhuatanga matua o ngā whatunga tauranga-toru me te-whā ko te wehenga, te hononga me te ahunga, ā, ko ngā uara o ēnei e whakamahia ana hei whakaahua i ngā hononga. He mutunga kore te ahunga me te wehenga o te hononga tino pai, me te tauwehenga hononga kua tīpakohia mō te tono e whakaarohia ana.
E whakaatu ana te hoahoa mahi i te Pikitia 1 i te mahi a te hononga ahunga, ā, whai muri ko te whakaahuatanga o ngā tawhā mahi e pā ana. Ko te hoahoa o runga he hononga 4-tauranga, kei roto ko ngā tauranga hono (whakamua) me ngā tauranga wehe (whakamuri, whakaata rānei). Ko te hoahoa o raro he hanganga 3-tauranga, e whakakore ana i te tauranga wehe. Ka whakamahia tēnei i roto i ngā tono e hiahia ana ki tētahi putanga hono whakamua kotahi anake. Ka taea te hono i te hononga 3-tauranga ki te taha whakamuri, ko te tauranga i honoa i mua ka huri hei tauranga wehe:
Pikitia 1: Taketakehononga ahungangā whirihoranga
Ngā āhuatanga mahi:
Tauwehenga Hononga: E tohu ana tēnei i te wāhanga o te mana whakauru (i P1) e tukuna ana ki te tauranga hono, P3
Te Ārahitanga: He ine tēnei i te kaha o te hononga ki te wehewehe i ngā ngaru e horapa ana i ngā ahunga whakamua me ngā ahunga whakamuri, e kitea ana i ngā putanga hono (P3) me ngā putanga wehe (P4).
Wehewehe: E tohu ana i te mana i tukuna ki te kawenga kore hono (P4)
Ngaronga Whakauru: Ko tēnei te whakaaro mō te mana whakauru (P1) i tukuna ki te tauranga (P2) i tukuna, ka whakaitihia e te mana i tukuna ki ngā tauranga hono me ngā tauranga wehe.
Ko ngā uara o ēnei āhuatanga i roto i te dB ko:
Hononga = C = 10 rākau (P1/P3)
Te ahunga = D = 10 log (P3/P4)
Wehenga = I = 10 rākau (P1/P4)
Ngaronga Whakauru = L = 10 rākau (P1/P2)
Ngā momo hononga
E toru ngā tauranga e taea te uru atu ki tēnei momo hononga, e whakaaturia ana i te Pikitia 2, kei reira te tauranga tuawhā e whakamutua ana ki roto hei whakarato i te aronga matua. Ko te mahi matua o te hononga aronga ko te tauira i te tohu wehe (whakamuri). Ko te whakamahinga noa ko te ine i te mana whakaata (VSWR rānei). Ahakoa ka taea te hono whakamuri, ehara tēnei momo hononga i te tauutuutu. Nā te mea kua whakamutua tetahi o ngā tauranga hono ki roto, kotahi anake te tohu hono e wātea ana. I te ahunga whakamua (e whakaaturia ana), ka tauira te tauranga hono i te ngaru whakamuri, engari ki te honoa ki te ahunga whakamuri (te Whakauru RF kei te taha matau), ka waiho te tauranga hono hei tauira o te ngaru whakamua, ka whakaitihia e te tauwehe hononga. Mā tēnei hononga, ka taea te whakamahi i te taputapu hei tauira mō te ine tohu, hei tuku rānei i tētahi wāhanga o te tohu putanga ki te ara iahiko urupare.
Pikitia 2: Hononga Aronga 50-Ohm
Ngā Painga:
1、Ka taea te whakapai ake i te mahi mō te ara whakamua
2, Teitei o te aronga me te wehewehe
3, Ka pāngia te ahunga o te hononga e te taurite ārai e whakaratohia ana e te whakamutu i te tauranga motuhake. Mā te whakarato i taua whakamutu ki roto ka whakarite kia pai te mahi.
Ngā ngoikoretanga:
1, Kei te ara whakamua anake te hononga
2, Kāore he raina hono
3, He iti iho te whakatauranga mana o te tauranga hono i te tauranga tāuru nā te mea kua tata memeha katoa te mana e pā ana ki te tauranga hono i roto i te pito o roto.
He whānuitanga o ngā hononga aronga a Si Chuan Keenlion Ngāruiti, he momo hononga whāiti me te whānui, e kapi ana i ngā auau mai i te 0.5 ki te 50 GHz. Kua hangaia hei whakahaere i te mana whakauru mai i te 10 ki te 30 watts i roto i te pūnaha tuku 50-ohm. Ka whakamahia ngā hoahoa moroiti, raina rānei, ā, ka arotauhia mō te mahi pai rawa atu.
Kei ngā waeine he hononga SMA, he hononga N rānei, he hononga 2.92mm, 2.40mm, me te 1.85mm rānei mō ngā wāhanga auau teitei.
Ka taea hoki e mātou te whakarite i teHononga Arongakia rite ki ō hiahia. Ka taea e koe te tomo ki te whārangi whakaritenga hei whakarato i ngā whakaritenga e hiahiatia ana e koe.
