High frequency module
First Claim
1. A high frequency module comprising:
- a dielectric substrate comprising a plurality of dielectric layers that are laminated together;
a power amplifier device mounted on a power amplifier device mounting portion that is formed on a first surface of the dielectric substrate;
a filter component mounted on a filter component mounting portion formed on the first surface of the dielectric substrate;
a first through-hole conductor which is formed under the power amplifier device mounting portion and penetrates through the dielectric substrate to a second surface thereof; and
a second through-hole conductor whose one end is exposed at the second surface of the dielectric substrate and which is provided between the power amplifier device mounting portion and the filter component mounting portion;
wherein the first through-hole conductor and the second through-hole conductor are connected to a thermal dissipation conductor on an upper surface of an external electric circuit board through a brazing material.

Abstract
There is presented a high frequency module, in which a recess 2a for mounting power amplifier device is formed on a lower surface of a dielectric substrate 2, and a recess 2b for mounting surface acoustic wave filter is formed on an upper surface of the dielectric substrate 2, and a power amplifier device 4 and a surface acoustic wave filter 8 are mounted through conductive bumps 3a and 3b on the recesses 2a and 2b, respectively. In addition, a through-hole conductor 11 whose one end is exposed at the lower surface of the dielectric substrate 2 is provided between the recesses 2a and 2b. The exposed end of the through-hole conductor 11 is attached to a thermal dissipation conductor 15 on an upper surface of an external electric circuit board 7 through a brazing material 13.
