Abstract:
1. A high-frequency module comprising: a diplexer including an antenna port to be connected to an antenna, the diplexer separating the frequency bands of first and second communication systems from a frequency band of a third communication system; a first high-frequency switch configured to separate a transmission signal of the first or second communication system from a reception signal thereof; a second high-frequency switch configured to separate a transmission signal of the third communication system from a reception signal thereof; and a third high-frequency switch configured to separate the reception signal of the first communication system from the reception signal of the second communication system, wherein each of the first, second, and third communication systems include a reception-signal output port, the diplexer and the first, second, and third high-frequency switches are integrated with one another on a layered body formed by layering a plurality of dielectric layers, a plurality of connection electrodes are formed on the layered body, one of the reception-signal output ports that output the respective reception signals of the first, second, and third communication systems is terminated with a chip capacitor, one of the connection electrode of the chip capacitor has a shape allowing a filter to be mounted instead of the chip capacitor, the one of the connection electrode is formed for mounting the chip capacitor and the filter, and a signal at the output of the one reception-signal output port is terminated with the chip capacitor to ground such that the output port is not connected to any reception circuit.
