Abstract
A synthesizer comprises a two-point modulation phase locked tow, TPM PLL, circuit configured to receive a frequency tuning signal and to generate a stepped chirp signal in an intermediate frequency range by applying a two-point modulation PLL on the frequency tuning signal, and a subsampling PLL circuit configured to receive the stepped chirp signal in a mm-wave frequency range and to generate a smoothened chirp signal in a mm-wave frequency range by applying a subsampling PLL on the stepped chirp signal.
