Magetsi amagetsi, monga chigawo chachikulu cha RF kutsogolo-end transmission channel, amagwiritsidwa ntchito makamaka kukulitsa chizindikiro cha RF champhamvu chochepa chopangidwa ndi modulation oscillation circuit, kupeza mphamvu yokwanira ya RF, ndikukwaniritsa makulitsidwe a RF pa njira yotumizira. .Magetsi amplifier amabwera ndi switch, fan, ndi magetsi, zomwe zimapangitsa kuti zikhale zosavuta komanso zachangu kugwiritsa ntchito.

Mfundo yogwirira ntchito ya amplifier mphamvu yonse imaphatikizapo njira zitatu:

Kulowetsa kwa siginecha, kukulitsa, ndi kutulutsa.Choyamba, chizindikiro cholowera chidzalowa mu amplifier kudzera muzolowera.Kenako, mutatha kukulitsidwa ndi gawo lopindula, chizindikirocho chidzakwezedwa kumlingo wofunikira.Pomaliza, chizindikiro chokwezera chidzaperekedwa kwa wolandila kapena mlongoti kudzera padoko lotulutsa.

Zizindikiro zake zazikulu zaukadaulo ndizotulutsa mphamvu komanso kuchita bwino.Momwe mungasinthire mphamvu zotulutsa ndikuchita bwino ndiye cholinga chachikulu cha ma RF amplifiers.Nthawi zambiri, mu RF magetsi amplifiers, LC resonant mabwalo angagwiritsidwe ntchito kusankha ma frequency ofunikira kapena ma harmonic kuti akwaniritse kukulitsa kosasinthika.Kuphatikiza apo, zigawo za harmonic zomwe zimatuluka ziyeneranso kukhala zazing'ono momwe zingathere kuti zisasokonezedwe ndi njira zina.
RF mphamvu amplifier wathunthu ali ndi ntchito zosiyanasiyana pagawo la kulumikizana.Ntchito yake yayikulu ndikupititsa patsogolo luso la kufalitsa chizindikiro kuti zitsimikizire kudalirika ndi kukhazikika kwa chizindikiro panthawi yotumizira.Mwachitsanzo, pankhani yolumikizirana opanda zingwe, zokulitsa mphamvu za RF zimagwiritsidwa ntchito kwambiri pazida monga mafoni am'manja, ma TV, ndi mawayilesi olumikizirana mawayilesi kuti apititse patsogolo luso lotumizira ma siginecha.Kuphatikiza apo, RF mphamvu amplifier yonse ndi chida chofunikira kwambiri mu radar, kulumikizana kwa satellite ndi magawo ena.

Qualwaveamapereka Power Amplifier Systems kuchokera ku DC kupita ku 110GHz, ndipo mphamvu imafika ku 200W.Kupindula kochepa ndi 15dB ndipo kulowetsa kwakukulu kwa VSWR ndi 3:1.Timapereka makina osiyanasiyana amplifier mphamvu kuti akwaniritse zosowa zanu zonse ku RF, microwave, ndi ma millimeter-wave amplifier zigawo.
