I come across an article on broadband drain bypass bias network. See attached schematic (Bias schem).
I understand that Z(L1) should be at least 10X the Z(drain) and Z(output matching) to avoid loading the matching. A 7.5nH inductor should be able to satisfy this at RFcarrier of 1.9GHz. See its Z(L1) plot (Figure2) from mwo (the other end of the i

Yes you have to use PORT2 with two tones to measure the IP3 of an amplifier...
Also you need to sweep the input power using Swept variable to plot IP3...
See the attached schematic setup...
If you still have problems then upload ur mwo file (*.emp) to help you better...

I'm trying to design a class B amplifier in mwo using two CGH40010 transistors, I have used transformer to bias the gate voltage. I'm not sure hot to set the input power and how to do the matching network for Class B amplifier.
Here attached is my schematics, could anyone help to point out what is

If you want just to do a simulation of the predistortion, mwo is ok for this purpose.
If you want to put in practice using some hardware driven by LabView, is possible the system to be too slow.
In general the predistortion algorithms are done by DSP processors which are very fast.

I want to design a 1.5 GHz power amplifier using UHF russian transistor 2T948A. His equivalent circuit is described in handbook. But I have a problem with creation this model in mwo, I think something wrong ( s21 very small - below 1, s22 high- above 1.5, real part of output impedance is negative). Does anybody have an experiance in (...)

I am looking for some matlab code that could model
the behaviour of HPA (AM/AM, AM/PM) with OFDM signal.
Is using Matlab a condition?
I suppose mwo can do this task much simper...
