hello guys,
i would like to know whether it is possible to upconvert a 100MHz frequency modulated signal to 900MHz using an upconverter ic

Ok...but all you need is a mixer which will use heterodyning & have 3 o/p's. Sum of frequencies, difference frequency & the original frequency, but you will need an i/p frequency from an oscillator.This could help you.....#-Link-Snipped-#

instead of using a mixer will an upconverter ic do?,
i dont know much about the mixer theory so if its possible i'd like to go directly for an upconverter ic

Its pretty difficult to get such an IC.In most of the cases though you will have to provide another i/p frequency.

i know of a few ic's like max2660-max2673

but i dont know if these can be used to upconvert a frequency modulated signal to higher frequencies!

Yes even I'm not sure because the FM signal will contain the carrier as well as the harmonics.
