摘要： A portable celullar phone apparatus includes a portable cellular phone and an external adapter for a portable cellular phone. It is possible to suppress an increase in output power of a portable cellular phone transmit amplifier due to a loss at a transmit switch associated with use of an external transmitting antenna by coupling a first output of the transmit switch to a portable cellular phone transmit amplifier and coupling a second output of the transmit switch to an input of a transmit amplifier part of a portable cellular phone external adapter. Deterioration of a NF of a receiving system due to a loss at a receive switch when using an external receiving antenna may be reduced by coupling a first input of a receive switch to a portable cellular phone receive amplifier and coupling a second input of the receive switch to an output of a receive amplifier part of the portable cellular phone external adapter.

In the non-weighted part, there is no electrode at a space out of the spaces which is closest to the separate electrode in the non-interdigitated region. This acoustic wave device prevents short circuits between the IDT electrode and the separate electrode, and provides excellent characteristics of suppressing unwanted waves.
