I want to have a FSK signal at 1500MHZ,I want to modulate AD9954(crystal 20MHZ ,PLL*20) at 100MHZ.
The DDS have a 1500MHZ spur at -40dBc relative ro main 100MHZ signal,
I want to filter out other spur signals and extract 1500MHZ and amplify it to 0dbm.
Is this a right way for FSK? What filter should I use and is better to remove spurs?
