LA XIRIIR HADA

Beddelayaasha Wajiga ee Buugga Hagaha Waveguide waa aalado aan firfircoonayn oo loo isticmaalo habaynta calaamadaha RF iyo microwave-ka kuwaas oo gacan ku hagaajin kara wejiga calaamadda. Waa muhiim codsiyada u baahan xakamaynta saxda ah ee wejiga calaamadda.

Ujeeddo:

1. Hagaajinta Wajiga: Beddelaha wejiga microwave-ka waxaa loo isticmaalaa in gacanta lagu hagaajiyo wejiga calaamadda si loo gaaro xakamaynta wejiga saxda ah. Tani aad bay muhiim ugu tahay isbarbardhigga wejiga iyo habaynta wejiga.
2. Magdhawga Wajiga: Beddelayaasha wajiga hirarka ee milimitir-ka ayaa loo isticmaalaa in lagu magdhabo qaladka wajiga ee nidaamka iyo in la hubiyo in wajiga calaamadda ee wadooyin kala duwan ay isku mid tahay, taasoo hagaajinaysa waxqabadka nidaamka.
3. Qaabaynta Beamforming: Iyadoo la hagaajinayo wejiga cutub kasta oo anteeno ah oo ku jira safka anteenada, qalabka isbeddelka marxaladda soo noqnoqda ee raadiyaha wuxuu gaari karaa qaabaynta beamforming iyo shaandhaynta beam.
4. Iswaafajinta Wajiga: Nidaamyada kanaalka badan, beddelka wejiga mm-mowjadda ayaa loo isticmaalaa si loo hubiyo in marxaladaha kanaal kasta ay isku mid yihiin, taasoo keentay in la gaaro iswaafajinta wejiga.

Codsiga:

Beddelaha wejiga RF wuxuu leeyahay codsiyo badan oo ku saabsan isgaarsiinta elektaroonigga ah, mid ka mid ah shaqooyinkiisa ugu muhiimsanna waa hagaajinta wejiga.
1. Nidaamyada isgaarsiinta, qalabka isbeddelka wejiga waxaa loo isticmaali karaa in lagu waafajiyo calaamadaha ka imanaya ilo ama waddooyin kala duwan si loo hubiyo inay gaaraan dhammaadka helitaanka iyadoo la raacayo marxaladda saxda ah. Iyadoo la hagaajinayo wejiga calaamadda gelinta, qalabka isbeddelka wejiga wuxuu buuxiyaa shuruudaha hagaajinta wejiga, taasoo hagaajinaysa waxqabadka nidaamka iyo xasilloonida.
2. Wareejiyeyaasha wejiga ayaa si weyn loogu isticmaalaa hababka wax-ka-beddelka iyo wax-ka-beddelka si loo hagaajiyo wejiga calaamadaha side-ka, si loo gaaro hoos-u-dhigga calaamadaha iyo aqoonsiga hababka kala duwan ee wax-ka-beddelka (sida PSK, QAM, iwm.).
3. Marka laga hadlayo isku-darka soo noqnoqoshada, qalabka wax ka beddelaya marxaladda soo noqnoqoshada raadiyaha ayaa loo isticmaali karaa in lagu hagaajiyo wejiga calaamadaha ee soo noqnoqoshada kala duwan, taasoo horseedaysa ujeeddada isku-darka soo noqnoqoshada.
4. Isgaarsiinta dijitaalka ah: Bidi.

Tani waxay door muhiim ah ka ciyaartaa meelaha sida isgaarsiinta wireless-ka iyo nidaamyada radar-ka.
