Which translates to roughly 0.22V There are several handy places on the web for doing conversions between dBm and voltage: http://www.raltron.com/cust/tools/voltage_to_dbm.asp To pick one at random. Assume 50 ohms impedance for all the daughtercards In RF system design, it's usual to talk in terms of power levels rather than voltages. What you'll generally find is that for RF componentry, maximum input levels are generally quoted in dBm (dB referenced to 1 milliwatt), and sometimes dbuV (dB referenced to 1 microvolt). -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
