I want to use RF signal switch, which is sine signal, voltage will be >0 and be <0, >100M frequency. Just like ADG901SCPZ-EP, seems that it is just handle the positive signal, right? Do you have any recommend?
addtional requirement, just one channel.
Sorry for the delayed response.
ADG9xx series switches can only pass DC voltage up to 0.5V DC and they don't operate on negative voltage.
I would like to recommend ADGM1304 SP4T MEMS switch which is operation from 0Hz/DC to 14GHz and can carry DC voltage up to +/-6V which suits your requirement.
Below is the link for the ADGM1304 product page
Let me know if you have any more queries.
