1. Cov ntsiab lus ntawm cov khoom
Tsim nyog siv nyob rau hauv ob-directional kis tau tus mob (tuaj yeem khaws cia) thiab teeb liab sib npaug ntawm kev sib kis ntawm ntau lub cev los yog qhov xav tau kev faib tawm siab. Txais PHILIPS, NEC imported power doubler modules. Lub suab pre-amplifier yog lub suab qis microwave raj thawb-rub amplifier kom muaj txiaj ntsig txaus. Nws muaj 1 input thiab 2 outputs, thiab txhua qhov kev sib txuas muaj kev tiv thaiv dhau tam sim no. Cov ceg tso zis lossis kev faib tawm tuaj yeem hloov pauv raws li nws. Muab ob npaug rau sib npaug yog siv, yog li kho cov chav kawm sib kis tau yooj yim thiab yooj yim. Attenuator thiab equalizer yog plug-in, yog li cov neeg siv khoom tuaj yeem xaiv qhov ruaj los yog kho tau. Kev ntseeg siab hloov lub zog (los yog lub zog linear) thiab nruj tsis muaj dej tsis zoo thiab tiv thaiv huab cua tiv thaiv kev ua haujlwm ruaj khov.
