<P>PROBLEM TO BE SOLVED: To provide a module for a mobile communication terminal, which is compact, has high reliability, and is capable of coping with a plurality of bands. <P>SOLUTION: By using both a calibration signal from a transmission system of a terminal and a received signal strength indicator (RSSI) of a reception system of the terminal, calibration for matching performance of an interference canceller and a tunable filter with optimal values is performed. Calibration data is held, and good transmission/reception characteristics are achieved by reading the data during an actual operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
