My current bodged together setup as 40/20/15/10M filters tied to a 4:1 RF switch (mini-circuits).
The "easy" design is the reference design for the AD9863 (they even have layouts you can use) but I wanted to see if I could make it so that the entry level version was very inexpensive and you could add money for more capability.
- edrxty 4y agoNice, that's a good band selection. With the 9863 you could pretty much cover everything without even mixing but you'd be looking at some high end FPGAs and processors
