microwave amplifier stabilization

[tsp]

Hi,

Could anyone tell me how to stabilize a microwave amplifer without
using feedback. I know the technique how I would use a smith chart
and see how much resistance I would need. However, I need to learn
more about this method. At the moment, all I know is how to use a
resistor in series or shunt. I have no idea how to use it as a
combination, eg. shunt and series... does anybody know how I would do
that????

Stabilize what ?
temperature ?
output power ?
gain ?
gain flatness ?
reflexions ?

Why not just buy one from minicircuits for 99 cents and not worry you little
head about it. ERA-3 (dc-6ghz)
