1. A high frequency circuit module, comprising:
a multilayer circuit substrate formed by alternately stacked insulating layers and conductive layers; a transmission filter that performs filtering on high frequency transmission signals; a reception filter that performs filtering on high frequency reception signals; and a first high frequency switch that switches connections of an antenna and the transmission and reception filters, wherein either one or both of the transmission filter and reception filter, and the first high frequency switch, are embedded in the multilayer circuit substrate, and wherein a first ground conductor is formed in a first conductive layer located above the first high frequency switch and each embedded filter in the multilayer circuit substrate, the first ground conductor being formed in regions facing at least the first high frequency switch and each embedded filter, and wherein a second ground conductor is formed in a second conductive layer located below the first high frequency switch and each embedded filter in the multilayer circuit substrate, the second ground conductor being formed in regions facing at least the first high frequency switch and each embedded filter. |
