I want to terminate drain stub with 50 Ohm to ground. Do not want to use capacitor or microstrip DC-block before that. Problem with capacitor or DC block is that it can reflect unwanted frequency back to transistor. But it seems that it is not good idea with 3v and 50 Ohms there would be 60mA flowing and need to use big resistor like 1206, and waste of energy. I read about microstrip spiral can be used with foam absorber glued to it, the only alternative i thought about.
