PURPOSE:To attain effective utilization of space on device constitution by fitting other components to a metallized side face of a dielectric filter of stable integral form so as to attain an integral structure. CONSTITUTION:A mixer 3 of rectangular parallelepiped shape is fitted to the metallized side face 2 of the dielectric filter 1 and the dielectric filter 1 fitted with the mixer 3 is accommodated in a mounting case 4. The mounting case 4 plays also a role of a shield case. Through the constitution above, the dielectric filter 1 and the mixer 3 are shielded mutually by means of the metallized side face 2 or the like. Then, the space and the accommodating case needed conventionally for mounting a mixer and a synthesis circuit or the like are saved remarkably and further, a coaxial cable for connection is eliminated. |
