Just in case you don't care for mathematical equations, here is a little cheat sheet table to help understand the correlation of VSWR to the percentage of reflected power that will return.
Just in case you don't care for mathematical equations, here's a little "cheat sheet" table to help understand the correlation of VSWR to the percentage of reflected power that will return. NOTES Here is a download of this cheat sheet:VSWR vs. Return Loss An article thatexplains VSWR This...
在上面的例子中 VSWR = ( 1 + 0.1) / ( 1 - 0.1) = ( 1.1 / 0.9 ) = 1.222:1 因此对于 20dB 的回波损耗,等效 VSWR 为 1.222:1 同样,将 Rho 代入 VSWR 等式, 按下式计算: VSWR = ( 1 + [ 10 ^ { RL/-20 }] ) / ( 1 - [ 10 ^ { RL/-20 }] ) Table ofCommonReturnLoss,Rh...
