Wireless communications equipment that wirelessly communicates signals on
a plurality of communication frequencies includes: a baseband frequency-side frequency
conversion means that performs conversion between baseband signals on the baseband
frequency and signals on a stipulated frequency higher than the baseband frequency
and different from the intermediate frequency, an intermediate frequency-side frequency
conversion means that performs conversion between the signals on said stipulated
frequency and intermediate frequency signals on a plurality of intermediate frequencies
corresponding to a plurality of communication frequencies, and an unwanted frequency
signal component removal means that removes signal components of unwanted frequencies
from the signals on said stipulated frequency. Thus, it is possible to share the
components used for the removal of unwanted frequency signal components for the
intermediate frequency signals of a plurality of intermediate frequencies, and
thus the cost and unit size can be reduced.
