“…This problem is exacerbated by the use of filters to reject the RX signal from the feedback path; the phase shift added by multiple poles or a high-Q resonance can easily destabilize the feedback path. Many works use a frequency-translational filtering technique [27,28,29,30,31,32], where the baseband filter can be constructed such that it does not affect stability significantly, and the two mixers in the loop effectively upconvert the baseband filter to be centered around the LO frequency.…”
