Abstract
There is presented a high frequency module, in which a recessfor mounting power amplifier device is formed on a lower surface of a dielectric substrate, and a recessfor mounting surface acoustic wave filter is formed on an upper surface of the dielectric substrate, and a power amplifier deviceand a surface acoustic wave filterare mounted through conductive bumpsandon the recessesand, respectively. In addition, a through-hole conductorwhose one end is exposed at the lower surface of the dielectric substrateis provided between the recessesand. The exposed end of the through-hole conductoris attached to a thermal dissipation conductoron an upper surface of an external electric circuit boardthrough a brazing material
