Abstract
There are provided a sampling filter that enables a filter characteristic to be adjusted flexibly, and a radio communication apparatus equipped with this sampling filter. A sampling filter apparatus () is equipped with four integration units (-through-) corresponding to the number of filter taps, and some of the integration units (-through-) include an integrator having an MEMS structure. By this means, a charge amount (accumulated charge amount) of a received signal integrated by an integrator can be adjusted by adjusting the capacity of an integrator having an MEMS structure. A received signal amount emitted from an integration unit can also be adjusted by adjustment of the integration amount of a received signal, enabling the filter characteristic of the sampling filter apparatus () to be adjusted flexibly.
