Theknoloji ea maqhubu a radio e se nang mohala: tlhahlobo ea melao-motheo le ts'ebeliso ea libaka tse ngata

RF (Radio Frequency) e bua ka maqhubu a motlakase a nang le maqhubu a pakeng tsa 3kHz le 300GHz, a bapalang karolo ea bohlokoa likhokahanong, radar, kalafo ea bongaka, taolo ea indasteri le likarolo tse ling.

Melao-motheo ea motheo ea maqhubu a seea-le-moea

Lipontšo tsa RF li hlahisoa ke li-oscillator, 'me maqhubu a phahameng a maqhubu a motlakase a fetisoa le ho phatlalatsoa ka li-antenna. Mefuta e tloaelehileng ea li-antenna e kenyelletsa li-antenna tsa dipole, li-antenna tsa lenaka le li-antenna tsa patch, tse loketseng maemo a fapaneng a ts'ebeliso. Sebaka sa ho amohela se khutlisetsa lets'oao la RF tlhahisoleseling e ka sebelisoang ka demodulator ho fihlela phetiso ea tlhahisoleseling.

Mefuta le mekhoa ea ho feto-fetoha ha maqhubu a seea-le-moea

Ho latela khafetsa, maqhubu a seea-le-moea a ka aroloa ka maqhubu a tlase (joalo ka puisano ea khaso), maqhubu a mahareng (joalo ka puisano ea mehala), le maqhubu a phahameng (joalo ka radar le kalafo ea bongaka). Mekhoa ea ho feto-fetoha ha molumo e kenyelletsa AM (bakeng sa phetiso ea lebelo le tlase), FM (bakeng sa phetiso ea lebelo le mahareng) le PM (bakeng sa phetiso ea data e potlakileng).

RFID: theknoloji ea mantlha ea boitsebahatso bo bohlale

RFID (radio frequency identification) e sebelisa maqhubu a motlakase le li-microchips ho fumana boitsebahatso ba othomathike, 'me e sebelisoa haholo ho netefatseng boitsebiso, tsamaiso ea thepa, temo le leruo la liphoofolo, tefo ea lipalangoang le mafapha a mang. Leha thekenoloji ea RFID e tobane le liphephetso tse joalo ka litšenyehelo le maemo, boiketlo ba eona le bokhoni ba eona bo khothalelitse nts'etsopele ea taolo e bohlale.

Tšebeliso e pharaletseng ea theknoloji ea RF

Theknoloji ea RF e khanya mafapheng a puisano e se nang mohala, puisano ea sathelaete, ho lemoha radar, tlhahlobo ea bongaka le taolo ea indasteri. Ho tloha ho marang-rang a WLAN ho ea ho li-electrocardiographs, ho tloha ho boipiletso ba lebala la ntoa ho ea ho lifeme tse bohlale, theknoloji ea RF e khothalletsa tsoelo-pele ea theknoloji le ho fetola mokhoa oa rona oa bophelo.

Leha thekenoloji ea RF e ntse e tobane le liphephetso, ka nts'etsopele ea mahlale le thekenoloji, e tla tsoela pele ho phunyeletsa le ho tlisa menyetla e mengata bakeng sa bokamoso!
