OK, so this probably seems like a fundamental sort of question, but I've noticed that there seem to be a couple of different places on the net describing quadrature receiver toplogies, and I want to know something fairly simple.
For a direct-conversion quadrature receiver, must you phase split *BOTH* the RF and LO inputs to the mixers? That is, do you need a 90 degree hybrid on both the RF and LO ports? -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
