Output power contours as a function of Gamma L

Hi all,

I am trying to produce output power contours as a function of the load reflection coefficients of my amplifier; does anyone have any idea how to do this in ADS?

To explain further, what I am trying to do is to let ADS tell me what are the load reflection coefficients that are going to result in a specific output power of ...dBm. That would be much in a similar way to how the gain and the noise circles work.

An example of what I am trying to do is in Gonzalez book (Microwave Transistor Amplifiers-Analysis and Design) which I am sure many of you have read. In the second edition, it is in page 355 figure 4.7.2(b). It comes under the High Power Amplifier Design section which is numbered 4.7 in chapter 4.

I would appreciate any ideas.

Thanking you in advance,
