Classification: CPC H | IPC H

Claim 0:
1. A radio-frequency module comprising:
a mounting substrate having a first main surface and a second main surface, the first and second main surfaces facing each other;
a power amplifier that is on a first main surface side of the mounting substrate;
a low-noise amplifier that is on a second main surface side of the mounting substrate;
a first transmission filter configured to pass a time division duplex (TDD) transmission signal;
a first reception filter configured to pass a TDD reception signal;
a second transmission filter configured to pass a frequency division duplex (FDD) transmission signal;
a second reception filter configured to pass an FDD reception signal; and
a plurality of external connection terminals,
wherein the first transmission filter is on the first main surface side of the mounting substrate, and
the first reception filter is on the second main surface side of the mounting substrate,
wherein the second transmission filter is on the first main surface side of the mounting substrate,
wherein the second reception filter is on the second main surface side of the mounting substrate,
wherein, as seen in a plan view of the radio-frequency module, the second transmission filter is between the first transmission filter and the power amplifier in a first direction,
wherein, as seen in the plan view of the radio-frequency module, the first reception filter is adjacent to the second reception filter in the first direction, and
wherein, as seen in the plan view of the radio-frequency module, the plurality of external connection terminals are adjacent to each other along the first direction and are between the low-noise amplifier and the first and second reception filters in a second direction, the second direction being orthogonal to the first direction.
