hi all, iam working on a signal that need modulation, am modulating a pulse and expecting the result as this picture
http://img97.imageshack.us/i/untitl3edn.png/
i will use an RF analog switch IC
http://www.analog.com/static/imported-files/data_sheets/ADG901_902.pdf
it will obtain to me the desired result ,but i have three questions about this RF switch
-the IC band is 4.5Ghz , does it work on low signal freqance cuz the two signals am using is 20 MHz carrier freqancy and 1 KHZ pulse freqancy
-do i need to put a coupling capacitors at the inputs ? , if so what is their values ?
-do i need to put a resistance at the output becuse in the datasheet there is a resistance at the output in the test circuits section.
sry for asking the too much questions but i can't find the answers in the datasheet...any help would be appreciated
