Abstract
A radio frequency module includes a transmit filter that allows a transmit signal of a band A for FDD to pass through, a receive filter that allows a receive signal of the band A to pass through, a filter that allows a transmit/receive signal of a band B for TDD to pass through, power amplifiers, a low noise amplifier, a switch between connecting the receive filter to the low noise amplifier and connecting the filter to the low noise amplifier, a switch between connecting the filter to the power amplifier and connecting the filter to the low noise amplifier, a matching circuit connected between the power amplifier and the transmit filter, a matching circuit connected between the power amplifier and the switch, and a module board. On the module board, each of the power amplifiers and the switch is arranged in between the matching circuit and the matching circuit.
