HADDA LA XIRIIR

Waveguide hal jiho iskutallaabeedku waxa uu ka kooban yahay laba hagaha mawjadaha xagal toosan.

Isku-xidhka waxa lagu gaaraa in laga bilaabo laba godad oo yaryar gidaarka guud ee hagaha mawjadaha. Naqshadeynta ka dib, awoodda calaamadda ee ku xiran labadan godadka isku-xirnaanta waa la rogi karaa oo la tirtiri karaa. Godadkan waxaa badanaa laga sameeyaa dalool yar oo iskutallaabta ah si loo gaaro waxqabad wanaagsan.

Lammaane-jiheeyaha labada jiho waa qayb dhigaya laba xariiq oo gudbinta meel u dhow si koronta hal xariiq ay ugu lamaanan karto kan kale. Lammaanuhu wuxuu la mid yahay cidhiidhiga sifada ee dhammaan afarta dekedood, taasoo sahlaysa in la dhexgeliyo wareegyada kale ama nidaamyada hoose. Iyadoo la qaadanayo qaabab isku xiran oo kala duwan, warbaahinta isku xirka, iyo hababka isku xirka, lammaanayaasha iskutallaabta ee hal jiho ah oo ku habboon nidaamyada microwave ee kala duwan oo leh shuruudo kala duwan ayaa la qaabayn karaa.

Codsiga soo noqnoqda sare ee hal jiheeyaha iskutallaabaha:

Microwave-ka hal jihada ah ee iskutallaabaha ah, oo ah qayb muhiim ah oo ka mid ah wareegyada microwave ee badan, ayaa si weyn loogu isticmaalaa nidaamyada elektiroonigga ah ee casriga ah. Waxaa loo isticmaali karaa in lagu bixiyo awoodda muunad ee magdhowga heerkulka iyo wareegyada kontoroolka baaxadda, waxayna dhamaystiri kartaa qoondaynta tamarta iyo isku-dubbaridka inta jeer ee ballaaran.
1. Cod-weyneeye dheellitiran, rf hal-ku-dhegayaasha isku-tallaabta jihada ah waxay caawisaa in la gaaro saamiga-gelinta-soo-saarka wanaagsan ee mawjadda taagan ee mawjada (VSWR).
2. Isku-darka isku-dheelitirka ah iyo aaladaha microwave-ka (sida falanqeeyayaasha shabakada), milimitirka mowjadda hal-geeska ah ee iskutallaabaha ah ayaa loo isticmaali karaa muunad dhacdada iyo calaamadaha muuqda.
3. Isgaadhsiinta mobaylka, isticmaalka isku xidhaha buundada 90 ° waxay go'aamin kartaa khaladka wajiga π/4 gudbiyaha shift keying (QPSK).

QualwaveWaxay siisaa lamaanayaasha iskutallaabaha jihada ah ee awoodda sare leh ee ballaaran min 1.13 ilaa 40GHz. Waxaa jira noocyo kala duwan oo ah dekedaha waveguide, sida WR-28 iyo WR-34. Lammaanayaasha iskutallaabaha jihada kaliya ee soo noqnoqda raadiyaha ayaa si weyn loogu isticmaalaa codsiyo badan.
