RF Circuit Basics

Li-circuits tsa RF ke li-circuits tse ikhethileng tse etselitsoeng ho sebetsa maqhubu a seea-le-moea, tse nolofalletsang puisano e se nang mohala le ts'ebetso e nepahetseng ea mats'oao. Li-circuits tsena li fapane le li-circuits tse tlase ho menahano ea meralo ea tsona, e hlokang tlhokomelo e hlokolosi bakeng sa ts'ebetso e nepahetseng.

Li-circuits tsa RF ke likarolo tsa bohlokoa lisebelisoa tse kang li-smartphone, li-routers tsa Wi-Fi, le mekhoa ea puisano ea sathelaete, e nolofalletsang khokahanyo le ts'ebetso ea matšoao. Ho utloisisa metheo ea li-circuits tsa RF ho bohlokoa bakeng sa ho rala li-PCB tse sebetsang hantle tse fihlelang litlhoko tsa theknoloji ea sejoale-joale.

Litlhaloso tsa RF Circuit Design

Ho rala li-circuits tsa RF ho kenyelletsa ho nahanisisa ka hloko ha lintlha tse joalo ka makhetlo a mangata, impedance, le botšepehi ba matšoao. Lintlha tsena li bohlokoa bakeng sa ho netefatsa ts'ebetso e nepahetseng ho li-RF PCB.

E 'ngoe ea liqholotso tsa mantlha moralong oa RF PCB ke ho ts'oara li-impedance, ho hokahanya tšitiso ea likarolo tse fapaneng tsa potoloho bakeng sa phetisetso e phahameng ea matla le lipontšo tse nyane tsa matšoao. Ho fihlella ho ts'oara ho nepahetseng ha impedance ho bohlokoa lits'ebetsong tsa maqhubu a holimo ho thibela ho senyeha ha matšoao.

Botšepehi ba matšoao ke taba e 'ngoe ea bohlokoa moralong oa RF PCB, e hlokang mekhoa e nepahetseng ea boenjiniere ho boloka boleng ba matšoao maemong a holimo. Lintlha tse joalo ka bolelele ba trace, routing, le tšitiso ea motlakase li tlameha ho laoloa ka hloko ho qoba ho sotha kapa tahlehelo ea mats'oao.

RF Traces ho PCB

Mesaletsa ea RF ke karolo ea bohlokoa ea moralo oa RF PCB, kaha e na le mats'oao a maqhubu a holimo a amehang tšitiso le tahlehelo ea matšoao. Ho ntlafatsa moralo oa trace oa RF ho bohlokoa bakeng sa ho netefatsa phetiso e tšepahalang ea mats'oao a RF ka har'a lisebelisoa tsa elektroniki.

Lintlha tsa bohlokoa bakeng sa RF Trace Design:

Bophara ba ho Latela: Bophara ba di-trace tsa RF bo bohlokwa bakeng sa ho boloka botsitso ba letshwao. Di-trace tse pharaletseng di fokotsa khanyetso le ho kenella ha letshwao, di fokotsa tahlehelo ya letshwao. Leha ho le jwalo, di-trace tse pharaletseng di ka boela tsa eketsa kotsi ya ho buisana le ho kena-kenana ha letshwao, kahoo ho lokela ho ba le botsitso ho latela ditlhoko tse ikgethang tsa potoloho ya RF.

Sebaka Pakeng tsa Mehlala: Sebaka pakeng tsa mehlala ea RF se bohlokoa bakeng sa ho fokotsa ho bua ka tsela e fapaneng le tšitiso. Sebaka se haufi se ka ntlafatsa botšepehi ba lets'oao empa se ka eketsa kotsi ea tšitiso. Sebaka se nepahetseng se khethoa ke makhetlo a lets'oao la RF le litlhoko tsa potoloho.

Ho Kopanya Phetiso ea Phetiso: Ho bapisa phetiso ea phetiso ea phetiso ea phetiso ea matla a mangata lipakeng tsa likarolo le ho fokotsa lipontšo tsa lets'oao. Ho bapisa phetiso ea phetiso e nepahetseng ho finyelloa ka ho rala ka hloko litekanyo tsa mesaletsa ea RF le likarolo tse tšoanang tse kang li-capacitor le li-inductor.

Ho thella: Ho thella hantle ho bohlokoa bakeng sa ho fokotsa lerata le tšitiso lipotolohong tsa RF. Mehlala ea RF e lokela ho pota-potiloe ke sefofane se tiileng sa fatše ho fana ka tsela ea ho khutla e nang le impedance e tlase bakeng sa lets'oao la RF.

Tsela ea ho Tsamaisa Matshwao: Ho tsamaisa mesaletsa ea RF ka hloko hoa hlokahala ho fokotsa tahlehelo le tšitiso ea lets'oao. Mesaletsa e lokela ho bolokoa e le khutšoanyane le e otlolohileng kamoo ho ka khonehang, ho qoba ho kobeha ho bohale le ho tšela mesaletsa e meng ka likhutlo tse nepahetseng.

Ho Sireletsa: Libakeng tse nang le lerata le phahameng, ho sireletsa ho ka sebelisoa ho sireletsa mesaletsa ea RF ho tšitiso ea kantle. Ho sireletsa ho ka finyelloa ka ho sebelisa mealo ea tšepe e sitsitsoeng fatše kapa thepa ea ho sireletsa e tsamaisang motlakase.

Teko le Netefatso: Hang ha RF PCB e se e hlophisitsoe, ho bohlokoa ho leka le ho netefatsa ts'ebetso ea mesaletsa ea RF ho sebelisoa lisebelisoa tsa teko ea RF. Sena se netefatsa hore PCB e fihlela litlhaloso tse hlokahalang bakeng sa botšepehi ba lets'oao le ts'ebetso.

Ka ho shebisisa lintlha tsena ka hloko le ho sebelisa mekhoa e metle molemong oa moralo oa trace oa RF, baenjiniere ba ka ntlafatsa ts'ebetso le ts'epahalo ea RF PCBs bakeng sa lits'ebetso tse fapaneng.

Khetho ea Lintho tsa PCB

Ho khetha thepa e nepahetseng ea PCB ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso le ts'ebetso ea RF PCBs. Khetho ea thepa e ama ka kotloloho thepa ea motlakase, litšobotsi tsa mocheso, le bokhoni ba phetisetso ea mats'oao a PCB.

Lisebelisoa tse loketseng tsa PCB bakeng sa lits'ebetso tsa RF li na le litšobotsi tse kang tahlehelo e tlase ea dielectric, conductivity e phahameng ea mocheso, le thepa e ntle ea phetisetso ea mats'oao. Thepa ena e netefatsa phallo e fokolang ea matla, phepelo e sebetsang ea mocheso, le phetisetso e tšepahalang ea lets'oao ka har'a potoloho ea RF.
