Waveguide ib qho kev taw qhia crossguide coupler muaj ob txoj cai angled waveguides.

Kev sib txuas yog ua tiav los ntawm kev pib ob qhov me me ntawm cov phab ntsa dav dav ntawm lub waveguide. Tom qab optimization tsim, lub teeb liab fais fab txuas los ntawm ob lub qhov txuas no tuaj yeem thim rov qab thiab muab tso tseg. Cov qhov no feem ntau yog ua rau hauv ib lub qhov me me kom ua tiav qhov kev ua tau zoo.

Ib qho kev taw qhia txuas txuas yog ib qho khoom siv uas tso ob txoj kab sib txuas sib ze kom lub zog ntawm ib kab tuaj yeem txuas mus rau lwm qhov. Lub coupler yog txuam nrog cov yam ntxwv impedance ntawm tag nrho plaub qhov chaw nres nkoj, ua rau nws yooj yim rau embed mus rau lwm yam circuits los yog subsystems. Los ntawm kev siv cov txheej txheem sib txuas sib txawv, kev sib txuas xov xwm, thiab cov txheej txheem sib txuas, cov kev taw qhia kev sib txuas tsim nyog rau ntau lub tshuab microwave nrog cov kev cai sib txawv tuaj yeem tsim.

Directional couplers, uas yog ib feem tseem ceeb ntawm ntau lub microwave circuits, yog dav siv nyob rau hauv niaj hnub electronic systems. Nws tuaj yeem siv los muab cov qauv ntsuas hluav taws xob rau qhov ntsuas kub thiab ntsuas qhov ntsuas hluav taws xob, thiab tuaj yeem ua tiav kev faib hluav taws xob thiab kev sib txuas ntawm ntau qhov ntau zaus.
1. Nyob rau hauv ib tug balanced amplifier, nws yuav pab kom ua tau zoo input-output voltage sawv yoj piv (VSWR).
2. Nyob rau hauv cov khoom sib npaug thiab cov khoom siv microwave (xws li network analyzers), nws tuaj yeem siv los ua piv txwv qhov xwm txheej thiab pom cov teeb liab.
3. Hauv kev sib txuas lus hauv xov tooj, kev siv lub 90 ° choj txuas txuas tuaj yeem txiav txim siab theem yuam kev ntawm π / 4 theem hloov keying (QPSK) transmitter.

Qualwavemuab broadband thiab siab zog ib qho kev taw qhia crossguide couplers nyob rau hauv ntau yam ntawm 1.13 mus rau 40GHz. Muaj ntau hom waveguide ports, xws li WR-28 thiab WR-34. Cov couplers tau dav siv hauv ntau daim ntawv thov.
