Hannes, thank you for your report and your nice words ! > > There are ICs called "digital down converters" from AD or Intersil... Does > anybody have ever tried to build an IQ-RX with those "guys"? Yes, the Analog Device AD6620 is one of them, and it is used in that variety of SDRs that do A-to-D conversion directly at RF, then digitally down convert the numeric stream to a more manageable (for the PC) sampling rate. The RFspace SDR-14 and SDR-IQ use that chip, as it does the newly announced QS1R by Phil Covington > And does anybody know if there are ICs that can do FFT up to 60Msps? I think > ATMEL had one (must be 1 or 2 years ago). Do you really need to do an FFT at 60 Msps ? And what will you do then with the frequency data ? That rate is way over what a PC can handle. You will be forced to use a hardware-only implementation... > Happy new year! Happy New 2007 to you too, and to all who are reading this. 73 Alberto I2PHD _______________________________________________ Winrad mailing list [email protected] http://winrad.org/mailman/listinfo/winrad_winrad.org
