PROBLEM TO BE SOLVED: To prevent local oscillator leakage and to achieve a low-noise index. SOLUTION: This multi-tap, digital-pulse driven mixer shifts a local oscillator frequency (FL0), from a reception frequency band for effectively preventing the leakage of a local oscillator 11. In this case, digital pulses 51 and 52 are used as a mixer drive signal 16, thus effectively realizing low noise index.
