A chirp linearity detector, integrated circuit, and method are provided. The chirp linearity detector comprises a phase-locked loop (PLL) frequency sampling circuit and a frequency sweep linearity measuring circuit. The PLL frequency sampling circuit comprises a frequency divider circuit for receiving a PLL output signal from a PLL and for providing a frequency divided output signal, a first low pass filter circuit for receiving the frequency divided output signal, for reducing harmonic mixing, and for providing a mixer input signal, a mixer circuit for receiving the mixer input signal, for mixing the mixer input signal with a local oscillator signal, and for providing a mixer output signal, a second low pass filter circuit for performing anti-aliasing filtering and for providing an analog-to-digital converter (ADC) input signal, and an ADC circuit for digitizing the ADC input signal and for providing a digital output signal.
