Ezinhlelweni eziningi ze-Bluetooth ezidinga ukusebenza okuphezulu nebanga elide noma usayizi omncane, onjiniyela bangathanda ukusebenzisa amamojula e-Bluetooth asekela izimpondo zangaphandle ku-PCBA yabo. Ngoba ngokuvamile indlela ephumelela kakhulu yokwenza uhla lokudlulisela lwemojuli ye-Bluetooth lube lude futhi wenze usayizi we-PCBA ube mncane, kungaba ukususa ingxenye yothi olusebhodini bese usebenzisa uthi lwangaphandle esikhundleni salokho.
Kodwa iyiphi indlela engcono kakhulu yokusetha uthi olungaphandle?
Ukuthatha i-PCBA enezingqimba ezimbili njengesibonelo:
1. Qiniseka ukuthi izingxenye ebhodini zihleleke kahle.
2. Qinisekisa ukuthi kukhona indawo enkulu yethusi eliphansi kanye nenani elanele lokudlula izimbobo.
3. Ulayini we-RF microstrip udinga ukwenza i-impedance engu-50-ohm, isendlalelo sereferensi siyisendlalelo sesibili.
4. Gcina isekethe yokufanisa yohlobo luka-π, bese ulenza libe seduze nesihlalo se-RF. Ngokulungisa iphutha lesekhethi efanayo, qinisekisa ukuthi i-antenna isesimweni esihle kakhulu.
5. Qinisekisa ukuthi ulayini we-RF microstrip uzungezwe ucingo lwaphansi (isihlangu).
6. Ungabeki ulayini wedatha, ulayini wewashi, njll. phansi kwemojuli, futhi ugcine okuphansi njengendiza yaphansi enkulu nephelele.
7.Kuhlanganiswe nomdwebo wesakhiwo sesendlalelo sesibili, kungabonakala ukuthi ulayini we-RF microstrip unezinhlangothi ezintathu ezizungezwe umhlabathi (isihlangu).
Sengiphetha, qiniseka ukuthi uthi lwe-antenna lwangaphandle lubekwe endaweni efanele, futhi uqinisekise ukuthi uthi aluthinteki kweminye imigqa esebhodini.
Uma unemibuzo ngesikhathi sokulungiselelwa kothi lwangaphandle, ungangabazi ukuxhumana no-Feasycom manje!
