Application here is to provide a signal of between 57 and 62 MHz at -5 to +12 dBm level (with ability to set) ( in 50 ohm system).
I'm considering what kind of topology to use. I like idea presented in Figure 9 and 10 of the AD9851 data sheet. It is easy for
me to add a DAC for some amplitude control.
I am so much of a beginner at this. I very much appreciate anyones advice or help, and any comment will be welcomed. Even if I have totally
incorrect approach I will be thankful to know.
1) What signal levels can I expect to be at the transformer output?
2) How much change will be available by using DAC like figure 10?
3) Plan is to put anti-alias filter at output of the transformer. Is this good choice, or is another better?
Thanks so very much for your kind attention.
