Transmitter Combiners

Lub tshuab hluav taws xob siab hluav taws xob sib txuas yog ib qho cuab yeej siv hauv xov tooj cua zaus (RF) tshuab los ua ke ntau lub teeb liab RF rau hauv ib qho kev tso tawm nrog lub zog siab. Nws yog ib qho tseem ceeb ntawm lub network ntawm RF fais fab sib faib thiab cov khoom sib txuas ua ke nyob rau hauv xws li ib txoj kev uas ib tus neeg tawm tswv yim teeb liab sib xyaw ua ke thiab tso tawm los ntawm ib qho chaw nres nkoj.

Cov khoom sib txuas ua haujlwm los ntawm kev siv cov khoom siv passive xws li lub zog faib hluav taws xob, cov kev taw qhia txuas, cov lim dej, thiab cov khoom siv hluav taws xob los faib lub zog ntawm ntau lub tswv yim tawm tswv yim. Cov input signals tau ua ke los ntawm kev siv lub zog sib xyaw ua ke, uas yog ib qho khoom siv uas siv lub hauv paus ntsiab lus ntawm superposition ntxiv rau tus kheej cov tswv yim teeb liab ua ke. Cov teeb liab ua ke yog ces amplified kom ncav cuag lub zog xav tau.
