| titleOfInvention | Frequency conversion circuit and receiver |
| abstract | An object of the present invention is to improve conversion efficiency in a subharmonic mixer using a higher-order harmonic component of a local oscillation signal. An RF signal input to a frequency converting unit is combined (multiplied) with a local oscillation signal Lo by a mixer, further sampled and held by a sample and hold circuit according to a timing signal, and passed through an LPF. And output as an IF signal. Local oscillation signal Lo generated by a local oscillation signal generating unit 31 is a signal of the frequency F Lo of approximately 1 / N of the frequency F RF of the RF signal, the timing signal SAMP generated by the timing adjustment circuit 35 The pulse signal is synchronized with the local oscillation signal Lo. The LPF 39 passes a low-band signal including the frequency of the difference frequency | F RF −F Lo × N | between the RF signal and the Nth harmonic of the local oscillation signal Lo, and blocks out-of-band frequency components.
