Abstract
The present invention discloses a multiband signal processing apparatus and method. The apparatus includes a multi-tone local oscillator signal generating unit and a multi-tone local oscillator signal transmission channel, where the multi-tone local oscillator signal transmission channel includes a band-pass filter and a frequency mixer. The multi-tone local oscillator signal generating unit is configured to generate a multi-tone local oscillator signal according to frequency response information of at least one device included in the multi-tone local oscillator signal transmission channel; the band-pass filter is configured to filter the received multi-tone local oscillator signal to obtain a filtered multi-tone local oscillator signal; and the frequency mixer is configured to perform frequency mixing on the multiband signal and the received multi-tone local oscillator signal.
