pi resistor network

Hi everyone,
In L or C band,we often use common RF resitors(0806) to form Pi shape attenuators between amplify modules to get suitable total amplification and
better return loss. I dont know whether the Pi resitor network can work up to
X band and Ku band? using the same resitors available in the market? or some special resitors
for high frequency?

Best regards,
Liu

0402 resistors have lower parasitics than 0805 resistors.
If you place two resistors in parallel it will minimize more the parasitic inductance and it will work with no problems in Ku band.
