RF block diagrams software design

[neazoi]

Hello, I am looking any software that can be used to design RF circuits using RF block diagrams. To have block diagram icons like mixers amplifiers filters etc.
Is there any lightweight freeware?

You could be interested in ADISimRF from analog devices.

Not entirely what I was looking for. I consider more drawing rather than calculate chatacteristics of a chain.
