Alexander Chemeris alexander.chemeris at gmail.comHi Christian, Why do you want 160MSPS DAC when you have only a USB connection? IIRC USRP1 in 16-bit mode could not do more then 8MSPS (i.e. 4MSPS in each direction). Btw, for about the same BOM cost you could get a single chip transceiver we use for UmTRX (http://www.limemicro.com/lms6002d.php). Though its tuning range is a bit higher - 375MHz-4GHz, so it doesn't fit if you need frequencies below 375MHz.
