Hartley image reject mixer
WebCompute the image-to-signal ratio at the ouput and divide it by the image-to-signal ratio at the input: Exercise: Prove that for For example, an IRR of 60 dB requires a phase mismatch of 0.1 degree. Typical IRR is around 30-35 dB. - Other issues in Hartley architecture: (1) voltage addition at the output; WebPage 8 of 16 Question 3 In the analysis of Hartley Image Reject Receiver, we have assumed that the phase of the desired and the image signals are synchronized with respect to the Local Oscillator (LO). Consider a more general case of the desired and image signals having an arbitrary phase relationship with the LO as shown in the figure below.

Web4.2.5 Image noise, image rejection, and mixers Consider a nondirect conversion receiver where the mixer is not designed to reject the image frequency, as depicted in Figure 4.28. Let us first present the problem of image noise and then discuss the remedies.
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.
