Patent ID: 8731486

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 that performs filtering in a first frequency band on a signal outputted from the transmission circuit; and a second reception filter that 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 overlap in part or are adjacent to each other in frequency, wherein the first transmission filter is embedded in the circuit substrate, wherein the second reception filter is embedded in a position in the circuit substrate at least a prescribed distance from the first transmission filter; wherein the first transmission filter and the second reception filter are respectively acoustic wave filters; and 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 transmission filter is disposed in a penetrating hole formed in the core layer.
