Thank you!
I'm not familiar with uwb, after little study I found the synthesizer is very hard to design.
kuouly, thank you! But I only know little about uwb, could you please give me the details why the pll is not needed, and what's the pulse circuit? I'm very interested in that! thank you!
biff44, I'm confused too. We just assumed the architecture is direct convertion, in fact, it's popular architecture, and the synthesizer gives I/Q LO signals, that's all, the base frequency is about several hunded MHz. Maybe I made a mistake, could you give me more suggestion? Thank you!
szekit, thank you, I just want to know, is there any chance to design a simple pll to realize it? If so, I'll try it, if not, I don't want to waste time on it, I'll just design it use many plls and ssb!
Thank you!
Best,
Alex
