 09 Jan 2004 4:08 a problem about impedance matching |
|
|
|
I am designing a TE10 cavity filter. And 50 ou microstrip is used as the input and output.I have two questions about impedance matching:
(1)The impedance of the input microstrip must match the impedance of the first cavity by impedance transform?
(2)The impedance of the filter network(including the input and output microstrip) must be 50 ou? How to get the impedance of the filter network
by simulation,such as HFSS,CST?
Thanks in advance!
