Hello,
The MRF21030 LDMOS family transistor is an old product, currently it is no longer manufactured.
In this case there are only older model versions available.
The latest MRF21030 ADS model you can find in Archived MET and Root LDMOS Models for Agilent's ADS v2001.1001

Please note that archived models from mentioned page are provided "as-is".
