Thank you for your suggestions! I had a question, you mentioned you had the same ground plane for all sections... Did you separate the power plane or did you share the power as well?
marce,
Thank you for the suggestions! I have skimmed through Ott's book and have a good idea of the isolation of the analog signals from the digital signals. In general though, do high-frequency analog components in the MHz range share the same power and ground with the lower kHz range analog...
Hello!
On a PCB I have RF, digital, and analog sections.
RF section has a strong +5 dBm LO feeding the mixer operating in the MHz range.
The analog section consists of an active filter working in the kHz range with much weaker -15 dBm signals.
In PCB practice, power planes (and sometimes...
Hello,
I know that you send digital signals using ASK, FSK, PSK modulation. I was wondering though if it was possible to send that same digital signal using FM or AM modulation?
If not, I was wondering if anybody knew of any popular ASK or FSK modulation IC's?
Thanks!
