I am a about to carry out a research on behavior of radio frequency amplifier for 5g network base station and I am having a challenge on how to get the software for simulation and also how to simulate ...I will be using a signal generator at mmwave a splitter,doharty amplifier,a combinier ,a circulator for load impedance matching, a filter, an antenna array and a network analyser to check the gain efficiecy and peak power .this will be done with and without a circulator to know if it will save cost and check for other parameters. My problem is that I don't know how to simulate and also where to connect the analyser so o can get all the measurement for the parameters I am interested in .I really need help because I have a background in computer engineering not electronics
