When I say impedance, it depends on the
capacitance and inductance. So, these two components depend on frequency (wL and
1/wC, where w= 2xpixF).




When I say characteristic impedance, it too
has capacitance and inductance involved. So when I say I maintain 50 ohm
characteristic impedance on my board... there may be lot of frequencies
involved in the design resulting in different characteristic impedance? then
how the board is said as a 50 ohm impedance controlled..?  


 


 


Thanks and regards,


Raj.
