A bandwidth of 2 GHz is more than enough for 0.0004 GHz signals.

There are smaller and cheaper devices. Do you need to switch two or four signals? At what voltage? Do you require automotive qualification?

Hello Clemens:

Yes, could you advise smaller and cheaper solutions for our reference?

(1)Do you need to switch two or four signals? -> Could you share all solutions we can choose which is suitable for our design ?

(2) At what voltage ? -> 1.8V to 3.3V .

(3) Need Automotive grade solutions

With automotive qualification, the SN3257-Q1 already is the cheapest and smallest solution.
