ADG918 RF switch

Simon88 Whereabouts in your schematic are you taking those scope plots?

There is only one schematic in my topic which is the schematic draw in LTspice. 

You couldn't see it?

Which point in the schematic were you measuring the plot in yellow above? 1, 2 or 3? Also, can you provide details of the signal on channel 3 on your scope plots.

Hi I was measuring the point of 2.  

Thank you. I terminated port 3 with a 50 ohms load. Do you need me to measure it without the 50 ohms load, right?

Based on your question, I shouldn't see any DC shift during the RF off time, right?

Is there a information in the datasheet indicate this parameter? 

Hi Simon88 ADG918 is an absorptive switch. So, any unused port is automatically terminated to 50-ohm. If you are measuring at point 2, you shouldn't be seeing any DC offset. Is there anything else connected to 2 when you are taking the plot?
