Hi,

I understand that when the load (ZL) matches the characteristic impedance (Zo), the reflection coefficient is zero using the following equation:

reflection coefficient = (ZL-Zo)/(ZL+Zo)

If the characteristic impedance is a complex value (e.g. 50+j10), should the load be 50-j10 (conjugate match) in order to have the reflection coefficient equal to zero? However, according to the reflection coefficient equation, a conjugate matched load won't give a zero reflection coefficient.

Thanks a lot for your help! Philip
