PROBLEM TO BE SOLVED: To provide a reception module which is adaptive to the wide band of a reception signal and the low frequency of an intermediate frequency signal and which satisfies the requirement of miniaturization and the reduction of cost and to provide a TDMA system receiver. SOLUTION: A reception module 10 is constituted of a low noise amplifier 11, an LC filter 12 being a high frequency filter, a Gilbert cell-type mixer 13 and baluns 141 to 143. A reception signal RF received by an antenna (not illustrated) is amplified by a low noise amplifier 11, passes through the LC filter 12, is mixed with a local oscillation signal LO by the Gilbert cell-type mixer 13 and is converted into an intermediate frequency signal IF.
