Figure 5

Time and frequency domain quantification of receiver signal without thermal noise at wide and narrow bandwidths ( Δ f = 125 MHz). Upper panel: in-phase/quadrature (I/Q) signal traces for f RX=2.125 GHz and the receiver lowpass filters 5 MHz (red lines) and 40 MHz (blue lines). Lower panel: power spectral densities and peakedness of the receiver signal for the receiver lowpass filters 5 MHz (red) and 40 MHz (blue). The thermal noise density is indicated by the horizontal dashed line. The width of the shaded band indicates the receiver noise figure (5 dB).
