Indlela yokwenza i-DIY i-RF Detector: Umhlahlandlela Ophelele

I-RF detector iyithuluzi elisebenziseka kalula elisetshenziselwa ukuthola nokuhlonza izimpawu zemvamisa yomsakazo endaweni ezungezile. Kusukela kumanethiwekhi angenantambo kuya kumaselula, i-RF detector ingaveza izinhlobo ezahlukene zezimpawu zemvamisa yomsakazo, okwenza kube ithuluzi elibalulekile ezinhlelweni eziningi. Lo mhlahlandlela uzohlola izimiso ezingemuva kwe-RF detectors, izingxenye ezidingekayo ukwakha imiyalelo eyodwa, isinyathelo ngesinyathelo yokuyakha, kanye namathiphu okuhlola nokuxazulula izinkinga. Ngaphezu kwalokho, sizohlola ukusetshenziswa kwe-RF detectors kanye nokucatshangelwa kokuphepha lapho sisebenza nazo.

Izimiso Ezisemuva Kwe-RF Detector

Umqondo wokuzwa

Umtshina we-RF udinga into yokuzwa, ngokuvamile uthi, ukuze uthole amasignali e-RF endaweni. Uma isignali ye-RF ikhona, ibangela i-current encane ukuthi igeleze othini.

Ukulungiswa

Okwamanje okukhiqizwa uthingo ngokuvamile kuyisignali ye-AC (alternating current), engakwazi ukukalwa ngokuqondile. Ngakho-ke, isinyathelo esilandelayo ukulungisa isignali ye-AC ibe isignali ye-DC (yamanje eqondile). Lokhu ngokuvamile kwenziwa kusetshenziswa i-diode noma i-rectifier circuit.

Ukuhlunga

Ngemva kokulungiswa, isignali ye-DC ingase iqukathe umsindo ongafuneki noma ukuphazamiseka. Ukuze ususe lokhu, isifunda sokuhlunga sivame ukusetshenziselwa ukushelela isignali ye-DC futhi kuqedwe noma yiziphi izingxenye ezingadingeki.

Isikhulisi

Okukhiphayo kwesekethe yesihlungi kuvame ukuba yi-voltage encane kakhulu ye-DC, okungase kudingeke ukuthi ikhuliswe ukuze kulinganiswe. Isekhethi ye-amplifier inyusa i-voltage, ikwenze kube lula ukukala.

Okukhiphayo

Umphumela wokugcina womtshina we-RF ugesi we-DC olingana namandla esignali ye-RF etholiwe. Le voltage ingalinganiswa kusetshenziswa i-voltmeter noma enye idivayisi yokulinganisa.

Izingxenye Ezidingekayo Ukuze Kwakhiwe Umtshina We-RF

Ukwakha umtshina we-RF kudinga izingxenye ezimbalwa ezibalulekile, okuhlanganisa:

1. I-Antenna: I-antenna ithola amasignali e-RF endaweni. Uhlobo lwe-antenna olukhethiwe luncike kububanzi befrikhwensi namandla esiginali ye-RF ezotholwa.
2. I-Diode: I-diode ilungisa isignali ye-AC isuka ku-antenna ibe isignali ye-DC.
3. Umphathi: Ama-Capacitor asetshenziselwa ukuhlunga umsindo ongafuneki kanye nokuphazamiseka esignali.
4. Ukumelana: Ama-resistors akhawula okwamanje kusekethe futhi anikeze ukuchema kwe-transistor.
5. I-Transistor: I-transistor ikhulisa isignali futhi ilawula inkomba ye-LED.
6. I-LED: I-LED ekhanyayo ikhanyisa ukukhombisa lapho kutholwa isignali ye-RF.
7. Umthombo wamandla: Ibhethri noma umthombo wamandla uhlinzeka nge-voltage kanye namanje ukuze unike amandla isekethe.

Amanani athile kanye nezinhlobo zezingxenye zizoncika kumklamo wesifunda okhethiwe. Ukukhetha izingxenye zekhwalithi ephezulu ezidizayinelwe imvamisa eqondiwe namandla esignali kubalulekile ekusebenzeni okuhle.

Isinyathelo Ngesinyathelo Imiyalo Yokwakha Umtshina We-RF

Nansi imiyalelo yesinyathelo ngesinyathelo yokwakha umtshina we-RF oyisisekelo:

Izinto:

• I-antenna (isb, intambo elula)
• I-Germannium diode (isb, 1N34A)
• I-Capacitor (isb, 0.1uF)
• I-Resistor (isb, 4.7k ohm)
• I-Transistor (isb, i-2N3904)
• LED
• Ibhethri (isb., 9V)

Amathuluzi:

• I-Soldering iron
• I-Solder
• Abasiki bezintambo / abahluzi
• Amaphilisi
• Ibhodi lesinkwa (kuyakhetheka)

Iziyalezo:

1. Namathisela i-antenna ohlangothini oluhle lwe-diode, bese uxhuma isiphetho esinegethivu se-diode ku-capacitor.
2. Xhuma esinye isiphetho se-capacitor kusisekelo se-transistor, bese uxhuma i-transistor emitter emhlabathini.
3. Sebenzisa i-resistor ukuze uvale ukuxhumana phakathi kwesisekelo se-transistor kanye netheminali yebhethri ephozithivu.
4. Xhuma umqoqi we-transistor emlenzeni owodwa we-LED, bese uxhuma omunye umlenze we-LED kutheminali yebhethri ephozithivu.
5. Nika amandla isekhethi ngokuxhuma itheminali yebhethri enegethivu phansi kanye netheminali ephozithivu yebhethri kusivikela.
6. Hlola isekethe ngokubamba uthi eduze nomthombo we-RF (isb, umsakazo noma umakhalekhukhwini). I-LED kufanele ikhanyise lapho kutholwa isignali ye-RF.

Amathiphu okuhlola nokuxazulula izinkinga

Nawa amanye amathiphu okuhlola nokuxazulula inkinga komtshina we-RF:

• Sebenzisa umthombo we-RF owaziwayo ukuhlola ukuzwela nokunemba komtshina.
• Hlola umthombo wamandla ukuze uqiniseke ukuthi iletha i-voltage efanele kanye neyamanje.
• Qinisekisa ukuthi konke ukuxhumana phakathi kwezingxenye kuvikelekile futhi kudayiswe ngokufanelekile.
• Hlola izingxenye nge-multimeter ukuze uqinisekise ukuthi zisebenza ngendlela efanele.
• Lungisa ukuzwela kwesekethe ngokushintsha amanani engxenye.
• Vikela isekethe ukuvimba ukuphazamiseka kwe-RF okungafunwa.
• Sebenzisa i-oscilloscope ukuze ubheke i-waveform yesiginali ye-RF ngokungahambi kahle.
