I think for passive components, we can say the insertion loss equals to the noise figure. However, RF switch is electronic switch, it's active device. I'd like to know how much noise it will generate as an active device instead of how badly it will decrease the noise performance as a linear two port network. By the way, I want to use AS193-73 from Skyworks. If you want to see how they specify the switch's performance, you can find it at **broken link removed**.
Thanks.
