Abstract
Disclosed are a frequency multiplier, a signal transmitter and a radar chip. The frequency multiplier includes a signal generator that is configured to receive an FMCW signal and output a square wave signal at a frequency same as a frequency of the FMCW signal; and a third harmonic amplifier that is coupled to the signal generator and is configured to amplify a third harmonic wave in the square wave signal and output a frequency-tripled FMCW signal. The above-mentioned solution can improve the generation efficiency of the frequency-tripled signal.
Claims20
A frequency multiplier, comprising:
- a signal generator, configured to receive a Frequency-Modulated Continuous Wave (FMCW) signal and output a square wave signal at a frequency same as a frequency of the FMCW signal;
- and
- a third harmonic amplifier, coupled to the signal generator and is configured to amplify a third harmonic wave in the square wave signal and output a frequency-tripled FMCW signal.
