Ọtụtụ ngwaọrụ eletrọnịkị nwere inductor RF. Maria del Mar Villarrubia, onye nyocha na mmepe nke ụlọ ọrụ Plummer kwuru, "Iji soro anụmanụ, tube iko etinyere na akpụkpọ anụ ụlọ anyị nwere ihe inductor n'ime." "Mgbe ọ bụla a malitere ụgbọ ala ahụ, a ga-emepụta nkwukọrịta ikuku n'etiti inductors abụọ, otu n'ime ụgbọ ala na nke ọzọ n'ime igodo."

Agbanyeghị, dị ka akụrụngwa ndị dị otú ahụ dị ebe niile, ndị inductor RF nwekwara ngwa akọwapụtara nke ọma. Na sekit resonant, a na-ejikarị ihe ndị a na-ejikọta na capacitors iji họrọ otu ugboro (dị ka sekit na-emegharị emegharị, voltaji na-achịkwa oscillator, wdg).

Enwere ike iji inductor RF na ngwa dakọtara impedance iji nweta nguzozi impedance nke ahịrị nnyefe data. Nke a dị mkpa iji hụ na nnyefe data dị mma n'etiti IC.

Mgbe ejiri ya dị ka RF choke, inductors na-ejikọta n'usoro na sekit iji mee ka ihe nzacha RF. Na nkenke, RF choke bụ ihe nzacha dị ala, nke ga-ebelata ugboro ole dị elu, ebe obere ugboro agaghị enwe ihe mgbochi.

Kedu uru Q bara?

Mgbe ị na-atụle arụmọrụ nke inductance, uru Q bụ ihe dị mkpa. Uru Q bụ ndeksi iji tụọ arụmọrụ nke inductance. Ọ bụ oke enweghị akụkụ eji atụnyere ugboro oscillation na ọnụego ọnwụ ike.
