Technically, one can use LTSpice as it features a transmission line model, but obviously it doesn't like dangling nodes (ie. open lines) and isn't really suited for that purpose anyway due to lack of RF-related measurements.
What other software can be used to do a schematic-level simulation of RF circuits with transmission lines and lumped elements? I want to model distributed filters (like made from coax), matching circuits (tuners or baluns) etc. Amplifiers would be nice, but not necessary.
