A one chip type front end composite module is provided to reduce a production cost, minimize an entire size of a mobile terminal and to reduce area taken by electronic components. A transceiver terminal(180) is mounted on a substrate and mutually converts an IF(Intermediate Frequency) signal and an RF(Radio Frequency) signal. An antenna switching terminal separately transmits a plurality of frequency band reception signals and includes the first bonding pad part. A power amplification terminal(130) connects low frequency/high frequency amplification elements by having the second bonding pad part, and is mounted to be adjacent to the transceiver terminal(180). The second matching circuit terminal(170) is connected with the second bonding pad part to receive an output signal of the power amplification terminal(130), and is connected with the first bonding pad part to transfer an output signal to the antenna switching terminal. A filter terminal(160) is mounted to be adjacent to the matching circuit terminal and removes a spurious of a transmission/reception signal between the matching circuit terminal and the antenna switching terminal. The first matching circuit terminal(140) connects the filter terminal(160) and connects the antenna switching terminal and the power amplification terminal(130) to match impedance.
