    Hello, I plan to design a multi-port RF net (a power combiner), they have different frequency input range in different ports, and one combine output port. For example, in port 1 2 3, input frequency is 300,400,500MHz, 1w power, and output RF power to 50-ohm system.

    I would like to know voltage and current value in components which are on my net. To design the net, ADS software simulation is easy to operate for me, and I can make AC scan to know all ports response, but in this method they have the same frequency at the same time, it’s not what I desired. If I like to set some constant frequency and power to drive every port, how to set simulation?

Thank you

I'd look at something like harmonic balance.

However, superposition tells us that we can just add together the contributions of each of the inputs, provided (and this is probably the key) you are not load-modulating your source.

Some friends also told me to use HB simulation, but the don't tell me how to set. In HB simulation, I checked help file and no found guide.
