Lub mixer feem ntau yog siv los ua ke ntau qhov system teeb liab mus rau hauv ib txheej ntawm cov khoom siv hauv tsev. Hauv kev siv engineering, RF Multiplexer nws yog qhov tsim nyog los ua ke ob zaus ntawm 800MHz C network thiab 900MHz G network kom tso tawm. Kev siv cov khoom sib txuas tuaj yeem ua kom muaj kev faib tawm sab hauv tsev ua haujlwm ib txhij hauv CDMA zaus band thiab GSM zaus band. Lwm qhov piv txwv yog nyob rau hauv lub xov tooj cua kav hlau txais xov, RF Multiplexer tom qab sib txuas cov tswv yim thiab cov teeb liab tawm ntawm ntau qhov sib txawv zaus (xws li 145MHZ thiab 435MHZ) los ntawm kev sib txuas, lub feeder yog siv los txuas rau lub xov tooj cua, RF Multiplexer uas tsis tsuas yog txuag tau ib qho feeder, tab sis kuj zam Cov teeb meem ntawm kev hloov ntawm cov kav hlau txais xov sib txawv.
Tsis tas li ntawd, nws yuav tsum tau muab sau tseg tias nyob rau hauv daim ntawv thov ntawm lub combiner, RF Multiplexer lub teeb liab pub txoj kev ntawm lub hauv paus chaw nres tsheb los yog repeater yog wireless, thiab lub hauv paus ntawm lub teeb liab yog ib tug dav spectrum, yog li nyob rau hauv tej lub sij hawm, RF Multiplexer nqaim. passband yuav tsum tau ua kom lub purity ntawm lub teeb liab; Lub teeb liab pub txoj kev ntawm lub transmitter yog ib tug cable, RF Multiplexer thiab lub teeb liab yog ncaj qha coj los ntawm ib tug ntseeg siab qhov chaw, thiab nws cov teeb liab qhov chaw yog ib tug nqaim spectrum teeb liab. RF Multiplexer vim hais tias lub hauv paus yog ib tug cab kuj zaus teeb liab, txoj kev pub mis yog ib tug cable, RF Multiplexer thiab tsuas yog cov channel muaj. Carrier zaus teeb liab, tsis muaj lwm yam cuam tshuam teeb liab. Yog li ntawd, RF Multiplexer qhov dav channel tsim ntawm cov khoom sib txuas ua tau zoo hauv kev siv tswv yim.
Raws li tus kws tshaj lijpassive Cheebtsamchaw tsim tshuaj paus, txais tos nug peb yog tias koj muaj cov khoom xav tau.
