WebJun 1, 2015 · Hartley image reject receiver, shown in Fig. 2, replaces the second LO mixing stage with a 90° phase-shift network. For example, an RC–CR network provides +45° shift in one path and a −45° shift in the other path. This simple phase-shift network has constant 90° phase difference at all frequencies, but equal gain only at ωIF2 =1/ (RC).
