Web- The IF-signal is typically digitized (LPF+ADC) for further processing on DSP. - The IF-signal bandwidth is thus limited by the ADC sampling rate Fs. - The ADC sampling rate Fs limits the maximum range of the radar R max: R max = Fs*c*2*S = Fs*c*2*(B/T chirp) (2) where c is the speed of light (m/sec), S is the ramp Slope (Hz/sec), B is ...

In communication systems, when the IF frequency is quite high, some low frequency spurs need to be filtered out, such as the half IF spur. To do this, design a band-pass filter. For a band-pass filter, it is not necessary to be symmetrical for low frequency and high frequency rejection.
