Ngā Whakamutu Dorp-In RF Ngaruiti

Ko te Whakamutu Taka-roto (e mōhiotia ana ko te ātete whakamutu maunga-mata) he wāhanga motuhake hangarau maunga-mata (SMT) i hangaia mō ngā ara iahiko matihiko tere-teitei me ngā ara iahiko auau reo irirangi (RF). Ko tana kaupapa matua he pehi i te whakaata tohu me te whakarite i te pono o te tohu (SI). Engari i te hono atu mā ngā waea, ka "tāpirihia" tika, ka "tāpirihia" rānei ki ngā wāhi motuhake i runga i ngā raina tuku PCB (pērā i ngā raina microstrip), ka mahi hei ātete whakamutu whakarara. He wāhanga matua ki te whakaoti rapanga kounga tohu tere-teitei, ā, e whakamahia whānuitia ana i roto i ngā hua whakauru, mai i ngā tūmau rorohiko ki ngā hanganga whakawhitiwhiti kōrero.

1. He mahi auau-teitei tino pai me te taurite ātete tika
Te ine i te ine ira tino iti (ESL): Mā te whakamahi i ngā hanganga poutū auaha me ngā hangarau rauemi matatau (pēnei i te hangarau kiriata angiangi), ka whakaitihia te ine ira parataiao (ko ngā uara ātete tino tika: Ka tuku uara ātete tino tika me te pumau), me te whakarite kia ōrite te aukati whakamutunga ki te aukati āhuatanga o te raina tuku (hei tauira, 50Ω, 75Ω, 100Ω), ka whakanui ake i te mimiti kaha tohu me te aukati i te whakaata.
Urupare auau tino pai: Ka mau tonu ngā āhuatanga ātete pumau i runga i te awhe auau whānui, he nui ake te pai ake i ngā ātete arai tuaka, radial rānei tuku iho.
2. Te hoahoa hanganga i whānau mai mō te whakaurunga PCB
Hanganga poutū ahurei: Kei te poutū te rere o te iahiko ki te mata o te papa PCB. Kei runga i te mata o runga me raro o te wāhanga ngā irahiko e rua, e hono tika ana ki te paparanga whakarewa me te paparanga whenua o te raina tuku, e hanga ana i te ara iahiko poto rawa atu, ā, e whakaiti nui ana i te kaha o te takahuri i puta mai i ngā taura roa o ngā ātete tuku iho.
Hangarau paerewa mō te whakairinga mata (SMT): Hototahi ki ngā tukanga huihuinga aunoa, he pai mō te whakaputanga nui, e whakapai ake ana i te whai huatanga me te ōritetanga.
Kiato, ā, he penapena wāhi: Mā ngā rahi iti o te kete (hei tauira, 0402, 0603, 0805) ka penapena wāhi PCB nui, ā, he mea tino pai mō ngā hoahoa papa kiato nui.
3. Te whakahaere kaha me te pono
Te whakamāraratanga mana whai hua: Ahakoa tōna iti, ka aro te hoahoa ki te whakamāraratanga mana, ka taea ai te whakahaere i te wera e puta ana i te wā e whakamutua ana te tohu tere-tiketike. He maha ngā whakatauranga mana e wātea ana (hei tauira, 1/16W, 1/10W, 1/8W, 1/4W).
Teitei o te pono me te pumau: E whakamahi ana i ngā pūnaha rauemi pumau me ngā hanganga pakari, e tuku ana i te kaha miihini tino pai, te ātete ki te ru wera, me te pono mō te wā roa, e pai ai mō ngā tono ahumahi uaua.
