Patent ID: 8725086

Claim:
A high-frequency circuit module, comprising: a circuit substrate that is provided with a transmission circuit and a reception circuit for a high-frequency signal; a first transmission filter performs filtering in a first frequency band on a signal outputted from the transmission circuit; and a second reception filter performs filtering in a second frequency band on a signal inputted into the reception circuit, wherein the first frequency band and the second frequency band are separated from each other by at least a prescribed frequency range therebetween, with one of the first frequency band and the second frequency band being at least 1 GHz and another thereof being less than 1 GHz, wherein the first transmission filter is mounted on the circuit substrate, wherein the second reception filter is embedded in the circuit substrate, and wherein the second reception filter is an acoustic wave filter; wherein the circuit substrate is a multilayer circuit substrate in which insulating layers and conductive layers are stacked, the circuit substrate having a core layer that is a conductive layer greater in thickness than another conductive layer and that functions as a ground, and wherein the second reception filter is disposed in a penetrating hole formed in the core layer.
