Cov kev siv tseem ceeb ntawm antennas thiab amplifiers nyob rau hauv satellite kev sib txuas lus hauv paus chaw nres tsheb yog raws li nram no:
1. Kav hlau txais xov: Satellite kev sib txuas lus teeb liab yuav tsum tau xa tawm ntawm lub kav hlau txais xov hauv av mus rau satellite thiab los ntawm satellite rov qab mus rau hauv av.Yog li ntawd, tus kav hlau txais xov yog ib qho tseem ceeb hauv kev xa cov teeb liab, uas tuaj yeem tsom rau lub teeb liab ntawm ib qho chaw thiab txhim kho lub zog thiab zoo ntawm cov teeb liab.
2. Amplifier: Lub teeb liab yog attenuated thaum lub sij hawm kis tau tus mob, yog li yuav tsum tau ib tug amplifier kom lub zog ntawm lub teeb liab thiab xyuas kom meej tias lub teeb liab yuav ncav cuag satellite thiab av receivers.Lub amplifier siv nyob rau hauv satellite kev sib txuas lus hauv paus chaw nres tsheb feem ntau yog ib tug low-noise amplifier (LNA), uas muaj cov yam ntxwv ntawm tsis tshua muaj suab nrov thiab siab nce, uas yuav txhim khu lub rhiab heev ntawm lub teeb liab tau txais.Nyob rau tib lub sijhawm, lub amplifier kuj tseem siv tau ntawm qhov kawg transmitter kom ua kom lub teeb liab kom ua tiav qhov kev sib kis ntev dua.Ntxiv nrog rau cov kav hlau txais xov thiab lub tshuab hluav taws xob, cov chaw nres tsheb sib txuas lus satellite xav tau lwm yam khoom siv, xws li RF cables thiab RF keyboards, kom ntseeg tau tias cov teeb liab sib kis tau zoo thiab tswj tau.
