View in Scopus Google Scholar [7] WebJan 1, 2024 · According to Hartley architecture, image rejection can be realized by introducing a 90-degree phase shift for the quadrature IF signals and adding them together. This operation can be performed using an electrical 90-degree hybrid coupler or an ADC followed by a digital signal processing (DSP) module [ 21 ].

WebMar 25, 2008 · The method has been applied to Hartley architecture of image-reject mixers that are used in low IF RF receivers. The method relies on measuring the amplitude differences and phase errors between the I/Q mixer signals and iterative tuning of digitally controlled capacitance arrays, which are located inside the phase shifters. 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). intel uhd family graphics https://connersmachinery.com
