I need to setup some simulations on QUCS for the RF circuit below:
Pin1 is IC's positive port and Pin2 is IC's negative port.
My initial goal is to investigate the circuit behavior on different frequencies and different lumped components values. After that, I want to calculate the impedance matching and best pcb transmission line.
I saw many QUCS examples, but all of those is using a single power source.
So, how can I setup a differential signal source on QUCS?
pointing to an example would be very helpful !
