PURPOSE:To attain thin profile and miniaturization by constituting incorporatedly a tuner comprising inductor and capacitor components. CONSTITUTION:A mixer 12 mixes input signals to be mixed inputted respectively to input terminals 13 and 14, outputs an intermediate frequency output signal to an output terminal 15 and supplies the signal to a tuner 16. The tuner 16 consists of a transmission line electrode 17 providing an inductance through the synthesis of a distributed inductor and a lumped inductor caused by bending the transmission line and a transmission line electrode 18 provided oppositely or in parallel with the transmission line electrode 17 via the dielectric or at its surface. Earth terminals of the transmission line electrodes 17, 18 are set in opposite direction to each other. |
