Hi friends,
The first time simulate load pull,a question about the DC block and DC feed components as attached photo,whether i need modify the cap. and RF choke values if i use another device and different frequencics simulated.Or i insert the device into the example directly(why?)?
Thanks,

No..
The values are sufficiently high for RF frequencies ( if they are higher than 100MHz )

Don't modify these values, it's acting as a bias tee. You can measure different devices in different frequency band with the same bias tee.
The simulation result is not depending on these values.

These caps and inductors are large enough. They hardly have any effect on smith chart for high frequency application.
