A. PCB Meafaitino ma Layer Fa'aputuga:

O le filifiliga o mea PCB ma faʻapipiʻi faʻapipiʻi o loʻo i ai se aafiaga taua i le faʻaogaina o le RF amplifier. O meafaitino e pei o le FR-4 o loʻo ofoina atu fofo taugofie mo faʻaoga maualalo, ae o mamanu maualuga e ono manaʻomia ai laminates faʻapitoa ma mea faʻapitoa dielectric.

e. Fa'afetauiga fa'aletonu ma laina fa'asalalau:

O le ausiaina o le fa'afetauiga o le fa'alavelave i le va o la'asaga ta'amilosaga fa'aola e taua tele mo le fa'atinoga lelei. E mafai ona ausia lenei mea e ala i le faʻaogaina o laina faʻasalalau ma fesoʻotaʻiga fetaui. Fa'ata'ita'iga fa'aaogā meafaigaluega fa'akomepiuta e pei o le ADS po'o le SimSmith e mafai ona fesoasoani tele i le fa'atulagaina ma fa'alelei lelei feso'ota'iga fa'afetaui.

C. Fa'avae ma RF Tu'uesea:

E taua tele le fa'avaeina ma le fa'amama RF e fa'aitiitia ai le pisa ma fa'alavelave. O iloiloga e pei o va'alele fa'apitoa i luga o le eleele, pa puipui, ma le talipupuni e mafai ona fa'aleleia atili ai le fa'atinoga o le fa'atele RF.

o. Fa'asologa o vaega ma le fa'asologa RF:

Fuafuaga fa'atulagaina vaega ma le fa'aeteete RF fa'ata'ita'iga e taua tele i le fa'aitiitia o a'afiaga fa'ama'i e pei ole fe'avea'i ma le malosi se'ese. O le mulimuli i faiga sili, e pei o le fa'apuupuu o fa'asologa o le RF ma aloese mai le pi'o 90-tikeri, e mafai ona fesoasoani i le fa'atinoina o galuega lelei.

4. PCB prototyping auala:

Faʻalagolago i le lavelave ma manaʻoga o le poloketi, e tele auala e mafai ona faʻaaogaina e faʻataʻitaʻi ai se RF amplifier PCB:

A. togitogiga DIY:

DIY etching e aofia ai le faʻaaogaina o laminates faʻapipiʻi kopa, fofo faʻapipiʻi, ma auala faʻapitoa faʻafeiloaʻi e fatu ai se PCB. E ui o lenei faiga e aoga mo mamanu faigofie, atonu e le o se mea lelei talu ai o le RF amplifiers e maaleale i le gafatia ma suiga impedance.

e. Au'aunaga fa'ata'ita'i:

Au'aunaga fa'apolofesa PCB fa'apolofesa e tu'uina atu fa'amatalaga vave ma sili atu ona fa'atuatuaina. O nei 'au'aunaga e ofoina atu meafaigaluega fa'apitoa, mea e sili ona lelei ma fa'agasologa o gaosiga. O le fa'aogaina o ia 'au'aunaga e mafai ona fa'avavevave ai fa'ata'ita'iga fa'ata'ita'iga fa'atusa RF ma fa'aleleia atili le sa'o.

C. Mea faigaluega fa'atusa:

Fa'aaogā meafaigaluega fa'atusa e pei ole LTSpice po'o le NI Multisim e mafai ona fesoasoani ile vaega muamua ole fa'ata'ita'iga a'o le'i faia fa'ata'ita'iga fa'aletino. O nei meafaigaluega e mafai ai e oe ona faʻataʻitaʻiina le amio a faʻasalalauga faʻamalosi, auʻiliʻili faʻasologa o faʻatinoga ma faia ni fetuunaiga talafeagai aʻo leʻi faʻatinoina meafaigaluega.

5. Su'e ma toe fai:

O le taimi lava e maeʻa ai le PCB prototype o le RF amplifier, e taua tele suʻega maeʻaeʻa e faʻamaonia ai lona faʻatinoga. O su'ega e mafai ona aofia ai le fuaina o fa'amaufa'ailoga autu e pei o le maua, leo leo, laina laina ma le mautu. Fa'alagolago i fa'ai'uga, e ono mana'omia ni suiga fa'asolosolo e fa'aleleia atili ai le mamanu.

6. Fa'ai'uga:

O le faʻataʻitaʻiina o se PCB mo se RF amplifier e le o se galuega faigofie, ae faʻatasi ai ma le fuafuaina lelei, malamalama, ma punaoa, e mafai ona ausia ma le manuia. O le malamalama i faʻavae o le PCB prototyping, RF amplifiers, ma iloiloga faʻapitoa e taua tele. E le gata i lea, o le filifilia o metotia faʻataʻitaʻi talafeagai ma suʻega maeʻaeʻa o le a maua ai se mamanu PCB atoatoa mo lau galuega faʻapipiʻi RF. O lea aua le faatuai e amata i lenei malaga fiafia e faʻaliliu ai au manatu faʻamalosi RF i le mea moni!

Mulimuli ane, RF amplifier PCB prototyping e manaʻomia se tuʻufaʻatasiga o tomai faʻapitoa, faʻataʻitaʻiga faʻataʻitaʻiga, ma auala saʻo faʻataʻitaʻiga. E ala i le mulimuli i laasaga o loʻo faʻamatala atu i lenei taʻiala, e mafai ona e amataina lau faigamalaga i le fatuina o se faʻamalosi RF maualuga e ala i le manuia PCB prototyping.
