Lub amplifier yog ib qho cuab yeej uas ua kom lub zog los yog lub zog ntawm cov teeb liab tawm tswv yim.Nws muaj lub raj xa hluav taws xob lossis transistor, lub zog hloov hluav taws xob, thiab lwm yam khoom siv hluav taws xob.Siv hauv kev sib txuas lus, tshaj tawm, radar, TV, tswj tsis siv neeg thiab lwm yam khoom siv.

Ib qho cuab yeej uas ua rau kom lub amplitude los yog lub zog ntawm lub teeb liab.Nws yog ib qho tseem ceeb ntawm cov teeb liab ua hauv ib qho cuab yeej automation.Kev ua haujlwm amplification ntawm amplifier yog pom tau los ntawm cov teeb liab tawm tswv yim los tswj lub zog, thiab lub zog siv hluav taws xob xav tau rau amplification yog muab los ntawm lub zog.Rau linear amplifiers, qhov tso zis yog qhov rov ua dua thiab txhim kho cov teeb liab tawm tswv yim.Rau nonlinear amplifiers, cov zis yog qhov ua haujlwm ntawm lub teeb liab input.Raws li lub cev kom muaj nuj nqis ntawm cov teeb liab ua amplifier tau muab faib ua txhua yam amplifier, electromechanical amplifier, hluav taws xob amplifier, hydraulic amplifier thiab pneumatic amplifier, ntawm cov uas feem ntau siv yog hluav taws xob amplifier.Nrog kev sib kis ntawm efflux thev naus laus zis (saib efflux keeb), daim ntawv thov ntawm hydraulic lossis pneumatic amplifiers tau maj mam nce.Cov khoom siv hluav taws xob tau muab faib ua lub tshuab nqus tsev vacuum amplifiers, transistor amplifiers, khoom amplifiers thiab magnetic amplifiers raws li cov khoom siv nquag siv, ntawm cov transistor amplifiers yog cov siv dav tshaj plaws.Transistor amplifiers feem ntau yog siv rau voltage amplification thiab tam sim no amplification ntawm cov teeb liab nyob rau hauv cov twj paj nruag tsis siv neeg, feem ntau nyob rau hauv daim ntawv ntawm ib qho kawg amplification thiab laub-rub amplification.

Lub hauv paus ntsiab lus: High zaus fais fab amplifier yog siv nyob rau theem kawg ntawm lub transmitter.Nws txoj haujlwm yog txhawm rau nthuav dav lub zog ntawm lub siab zaus modulated yoj teeb liab kom ua tau raws li qhov xav tau ntawm kev xa lub zog, thiab tom qab ntawd radiate nws mus rau hauv qhov chaw los ntawm tus kav hlau txais xov kom paub meej tias tus txais hauv ib cheeb tsam tuaj yeem tau txais cov teeb liab txaus siab, thiab tsis cuam ​​tshuam nrog kev sib txuas lus ntawm cov channel uas nyob ib sab.

High zaus fais fab amplifier yog ib qho tseem ceeb ntawm cov khoom sib kis hauv kev sib txuas lus.Raws li qhov dav ntawm nws qhov ua haujlwm zaus band, nws tuaj yeem muab faib ua nqaim-band high-frequency power amplifier thiab wide-band high-frequency power amplifier.Narrow-band high-frequency hwj chim amplifier feem ntau siv lub zaus xaiv Circuit Court nrog kev ua haujlwm ntawm kev xaiv zaus lim raws li lub voj tso zis, yog li nws tseem hu ua tuned fais fab amplifier lossis resonant zog amplifier.Cov zis hluav taws xob ntawm lub tshuab hluav taws xob dav dav dav dav yog lub tshuab xa hluav taws xob lossis lwm qhov sib txuas sib txuas, yog li nws tseem hu ua untuned power amplifier.High-frequency hwj chim amplifier yog ib yam ntawm lub zog hloov dua siab tshiab ntaus ntawv, uas converts DC lub zog muab los ntawm lub hwj chim mov mus rau high-frequency AC tso zis.Nws yog paub nyob rau hauv cov chav kawm ntawm "Low zaus Electronic Circuit Court".Raws li qhov sib txawv tam sim no conduction Angle, lub amplifier tuaj yeem muab faib ua A, B, C peb hom kev ua haujlwm.Tam sim no ntws lub kaum sab xis ntawm Class A amplifier yog 360o, uas yog tsim rau cov teeb liab me me thiab tsis tshua muaj zog amplification.Tam sim no ntws lub kaum sab xis ntawm Class B amplifier yog hais txog 180o;Class C amplifier tam sim no ntws lub kaum sab xis yog tsawg dua 180o.Ob Chav B thiab Chav C yog tsim rau kev ua haujlwm siab.Lub zog tso zis thiab kev ua haujlwm ntawm Class C ua haujlwm yog qhov siab tshaj plaws ntawm peb qhov kev ua haujlwm.High zaus lub zog amplifiers feem ntau ua haujlwm hauv chav kawm C. Txawm li cas los xij, qhov cuam tshuam ntawm cov nthwv dej tam sim no ntawm Class C amplifiers yog qhov zoo heev uas yuav tsum tau siv rau kev siv hluav taws xob tsawg zaus, thiab tsuas yog siv tau rau resonant zog amplification nrog lub voj tuned raws li lub thauj khoom.Vim tias muaj peev xwm lim dej ntawm qhov ntsuas hluav taws xob, qhov hluav taws xob tam sim no thiab qhov hluav taws xob tseem nyob ze heev rau qhov sinusoidal waveform thiab qhov distortion tsawg heev.
