I need to generate a square wave that will modulate an RF signal sitting at 2.8GHz, looking at the app note AN-0996 the direct conversion architecture would work, however I'm looking for a simple solution for the waveform generation essentially control of the magnitude, phase and timing for the I/Q channels. Can you please suggest an appropriate hardware solution.. a modulation bandwidth of 100MHz should suffice.
I'm not sure if I'm referencing to the same resource with you. I'd like to know if you are referring to this version of AN-0996 document .
Correct that is the App Note that I was referring to.
