Makina Othandizira Mphamvu RF Makina Oyesera a BroadBand Amphamvu Kwambiri Millimeter Wave High Frequency

Kulowetsa chizindikiro, kukulitsa, ndi kutulutsa. Choyamba, chizindikiro cholowetsa chidzalowa mu amplifier kudzera mu mawonekedwe olowera. Kenako, pambuyo pa kukulitsa ndi gawo la gain, chizindikirocho chidzakulitsidwa kufika pamlingo wa mphamvu wofunikira. Pomaliza, chizindikiro chokulitsidwacho chidzatulutsidwa ku wolandila kapena antenna wotsatira kudzera mu doko lotulutsira.

Zizindikiro zake zazikulu zaukadaulo ndi mphamvu yotulutsa ndi magwiridwe antchito. Momwe mungakulitsire mphamvu yotulutsa ndi magwiridwe antchito ndiye cholinga chachikulu cha mapangidwe a makina a RF power amplifier. Nthawi zambiri, mu makina a RF power amplifier, ma LC resonant circuits angagwiritsidwe ntchito kusankha ma frequency oyambira kapena harmonic inayake kuti akwaniritse kukulitsa kosasinthika. Kuphatikiza apo, zigawo za harmonic zomwe zili muzotulutsa ziyeneranso kukhala zazing'ono momwe zingathere kuti zisasokonezedwe ndi njira zina.

Makina onse a RF power amplifier ali ndi ntchito zosiyanasiyana pa ntchito yolumikizirana. Ntchito yake yayikulu ndikuwonjezera mphamvu yotumizira ma signali kuti zitsimikizire kudalirika ndi kukhazikika kwa signali panthawi yotumizira.

Mwachitsanzo, pankhani yolumikizirana opanda zingwe, makina olumikizirana amphamvu a RF amagwiritsidwa ntchito kwambiri pazida monga mafoni am'manja, ma TV, ndi malo olumikizirana pa wailesi kuti apititse patsogolo luso lotumiza ma signal. Kuphatikiza apo, makina onse olumikizirana amphamvu a RF ndi chida chofunikira kwambiri pakulankhulana kwa radar, satellite ndi zina.
