Rdson is around 200 ohms then you'll lose 1/5th of the signal.


J108 - 8 ohms typical.


Those seem to be kind of hard to get these days.


I doubt that the load needs to be as low as 1k either.


Yep, got to find a compromise between loss and leakage. However, with
T-switches leakage isn't such an issue.
