Patent ID: 7565116

Claim:
A high frequency module comprising: a layered substrate including dielectric layers and conductor layers alternately stacked, the layered substrate having a top layer, a bottom layer, and inner layers between the top and bottom layers; a transmission circuit for processing transmission signals; a reception circuit for processing reception signals; a first region in which components making up a path of the transmission signals are located whereas components making up a path of the reception signals are not located, the first region being located inside the inner layers of the layered substrate; and a second region in which the components making up the path of the reception signals are located whereas the components making up the path of the transmission signals are not located, the second region being located inside the inner layers of the layered substrate, wherein the transmission circuit is located in the first region, and the reception circuit is located in the second region, the high frequency module further comprising a conductor portion that is connected to a ground and disposed between the first region and the second region inside the inner layers of the layered substrate and that electromagnetically separates the transmission circuit and the reception circuit from each other.
