<p>PROBLEM TO BE SOLVED: To provide a front-end device that is reduced in size while maintaining a processing function.SOLUTION: A front-end device 1 includes a high-order device 11 and a low-order device 21. The high-order device 11 has an S/P interface unit 11a. The low-order device 21 has a parallel interface unit 21a and a high-frequency processing unit 21b. The S/P interface unit 11a is connected to an RFIC 31 and the parallel interface unit 21a, receives a serial signal from the RFIC 31, converts the serial signal into a parallel signal, and transmits the parallel signal to the parallel interface unit 21a. The parallel interface unit 21a receives the parallel signal and transmits the parallel signal to the high-frequency processing unit 21b. The high-frequency processing unit 21b is connected between the RFIC 31 and an antenna and performs a predetermined processing for a high-frequency signal on the basis of the parallel signal.</p> |
