VHF Couplers

Ib tug VHF hybrid coupler yog ib tug passive ntaus ntawv uas combines los yog splits signals nyob rau hauv ib tug VHF (hloov ntau zaus). Nws yog feem ntau siv hauv RF (xov tooj cua zaus) tshuab rau kev sib cais cov cim, sib txuas cov teeb liab, thiab rau kev sib tw kav hlau txais xov. Cov kev siv ntau tshaj plaws ntawm VHF hybrid coupler muaj xws li kav hlau txais xov sib txuas / sib cais, teeb liab faib, thiab impedance txuam. Hauv cov kav hlau txais xov sib txuas/splitting, hybrid coupler yog siv los ua ke lossis faib cov cim ntawm ob lub kav hlau txais xov, tso cai rau ntau lub kav hlau txais xov siv rau tib lub cev. Hauv kev faib cov teeb liab, lub hybrid coupler yog siv los faib cov teeb liab mus rau ntau qhov kev tso tawm, tso cai rau cov teeb liab mus rau qhov chaw sib txawv. Hauv kev sib piv impedance, hybrid coupler yog siv los ua kom haum rau qhov impedance ntawm ob lub ntsiab lus kom txo tau qhov kev xav thiab txhim kho cov teeb liab zoo.
