It is mentioned in Razavi book that the choice between transmission lines and lumped inductors in distributed amplifier design depends on the frequency and environment, and the transition from one to the other takes place at 20-40 GHz.
I want to design a DA in the Ka band (27-40GHz) , and the first question coming to mind is whether to use actual lines or realize them using lumped inductors. I can't find anything in any reference books or papers regarding on what basis the choice can be made in the 20-40GHz frequency band. I know the pros and cons of each, but I still can't choose specifically. Any relevant information could be helpful.
