Quadrature chirp generation

A system comprising:

• a digital front-end (DFE) configured to generate a command signal;
• a sweeper configured to generate a first local oscillator (LO) signal and a second LO signal based on the command signal;
• a mixer configured to generate a mixed signal based on the first LO signal and the second LO signal;
• a divide-by-two frequency divider configured to generate an intermediate in-phase signal and an intermediate quadrature signal based on the mixed signal;
• an amplifier configured to:
• generate an in-phase signal based on the intermediate in-phase signal and an amplification setting;
• and
• generate a quadrature signal based on the intermediate quadrature signal and the amplification setting.

A system comprising:

• a digital front-end (DFE);
• a sweeper electrically coupled to an output of the DFE;
• a mixer electrically coupled to an output of the sweeper;
• and
• an amplifier electrically coupled to an output of the mixer and an output of the DFE;
• a first sweeper circuit electrically coupled to the output of the DFE and an input of the mixer;
• and
• a second sweeper circuit electrically coupled to the output of the DFE and the input of the mixer.
