    Abstract: A reception filter is configured to separate a transmission frequency (TX1) and a reception frequency (RX2), while a reception filter is configured to separate a transmission frequency (TX2) and a reception frequency (RX1), whereby the size reduction of the reception filters can be achieved. This is because the difference between the transmission frequency (TX1) and the reception frequency (RX2) and the difference between the transmission frequency (TX2) and the reception frequency (RX1) each are greater than the difference between the transmission frequency (TX1) and the reception frequency (RX1) and also greater than the difference between the transmission frequency (TX2) and the reception frequency (RX2), with the result that the reception filters require no steep filter characteristics.
