Regarding ADG918 switch

I am using ADG918 switch in my design.My query is regarding the DC biasing of the device.


Can the input and output of the switch both be simultaneously capacitively coupled to the source and load sides respectively? What is the maximum input allowed in this situation?


I have made a potential divider using 1.8k and 470 ohm at the output (RFC) to raise the input potential to about 0.5V with a 2.5 V supply. My frequency of operation is up to 200 MHz. Please advise whether the scheme is ok?
