Hi,
I am simulating an LNA for NF. I loaded the antenna S parameters to the input port. But when running the simulation there was a problem "No DC convergence" I am using a spice model for the main transistor. Simulating the LNA with 50R is ok, but the problem comes when loading the antenna S11 into the port 1.
Does anyone have an idea of what´s going on?
Thanks.
