Abstract
A local oscillator generation system includes a first frequency divider configured to divide frequencies of a first voltage controlled oscillator signal and a second voltage controlled oscillator signal by 2, and output a first divided signal and a second divided signal; a mixer configured to mix the first voltage controlled oscillator signal, the second voltage controlled oscillator signal, the first divided signal, and the second divided signal, and output a first frequency mixed signal and a second frequency mixed signal; a transimpedance amplifier configured to amplify the first frequency mixed signal and the second frequency mixed signal, and output a first amplified signal and a second amplified signal; and a band-pass filter configured to filter the first amplified signal and the second amplified signal, and output a first filtered signal and a second amplified signal.
