Hello,

Is it possible to setup the AD834 for frequency modulation? If so, could someone post an application circuit?
Thank you.
 

Hardly. Frequency modulation can be performed directly by a voltage controlled oscillator and indirectly by a variable delay or phase shift element.
 

An analog multiplier can be use for various types of AM modulation, but not directly for FM modulation. For that you need a device whose phase or frequency can be varied.
