Fernsehsignalempfängstuner

摘要

A television signal receiving tuner comprises: an integrated circuit including a mixer (1) and an intermediate frequency circuit (5) which frequency convert at least a received television signal RF to an intermediate frequency signal IF; a first intermediate frequency amplifying circuit (3) which is separate from the integrated circuit (1) and has an amplification degree; and an SAW filter (4) which is separate from the integrated circuit (1) and attenuates adjacent bands out of the intermediate frequency band BW of the television signal by a predetermined attenuation amount. The integrated circuit (6) has at least a first terminal (8) and a second terminal (9) and outputs the intermediate frequency signal IF obtained by the frequency conversion by the mixer (1) from the first terminal (8), and the intermediate frequency signal is serially passed through the intermediate frequency amplifying circuit (3) and the SAW filter (4) and supplied from the second terminal (9) to the intermediate frequency circuit (5).
