<p>A band detecting circuit (60) determines, based on a downstream signal received from a radio base station apparatus (11), whether the downstream band used for the transmission of the downstream signal is a band A or a band B. Switches (48,49) are controlled, based on a result of that determination, to connect one of first and second bandpass filters (46,47) between a duplexer (43) and an upstream amplifier (51).</p> |
