As an example, the second switch (403 in FIG. 4B) is connected to the second power amplifier (410 in FIG. 4B) corresponding to the path (410 in FIG. 4B) of the second band at the terminal of the second driving amplifier (401 in FIG. 4B) of the second band. It can be controlled to selectively connect among 405 in 4b) and the first power amplifier (305 in FIG. 3b) corresponding to the path of the first band (310 in FIG. 3b).

For example, the second power amplifier (405 in FIG. 4B) is a power amplifier corresponding to the second band and can be distinguished from the first power amplifier (305 in FIG. 3B) corresponding to the first band. For example, the input terminal of the second power amplifier (405 in FIG. 4B) is controlled to be connected to the second driving amplifier (401 in FIG. 4B) with the second switch (403 in FIG. 4B) in between, and the second power amplifier (401 in FIG. 4B) The output terminal of 405) of FIG. 4B can be controlled to be connected to a third switch corresponding to the SPDT switch.

Referring to FIG. 4A, in operation 433, the second signal (211b in FIG. 4B) amplified by the second power amplifier (405 in FIG. 4B) passes through the third switch (407 in FIG. 4B) and the antenna switch 311. Thus, it can be controlled to be output through the antenna 205.

As an example, referring to FIG. 4B, in the electronic device 101 according to an embodiment of the present disclosure, a second signal (211b in FIG. 4B) of a second band corresponding to an operating band lower than the first band is received. In this case, the signal may flow along a path (410 in FIG. 4B) where the amplified signal is input to the second power amplifier (405 in FIG. 4B) corresponding to the second band and output through the antenna 205. For example, in the electronic device 101 according to an embodiment of the present disclosure, when receiving the second signal (211b in FIG. 4B), the second power amplifier (405 in FIG. 4B) outputs the signal from the first power amplifier (FIG. 3B).

Referring to FIG. 5A, in operation 503, the electronic device 101 may determine whether a higher transmission power than the transmission power that the second power amplifier (405 in FIGS. 4B and 5B) can output is required. For example, when transmitting a signal with a power of about 26 dBm or more, the electronic device 101 of the present disclosure may be preset to use the first power amplifier. In this case, when a situation occurs in which a signal must be transmitted with a power exceeding the power level set in the electronic device 101, it is necessary to control the signal path to use the first power amplifier.

In this case, the electronic device 101 may determine that a higher transmission power is needed than the transmission power that the second power amplifier (405 in FIGS. 4B and 5B) can output. For example, the electronic device 101 may operate in a situation where large amplification is required for the second signal of the second band (211b in FIG. 4B) (for example, when the transmission power required by the network is large, and/or In cases where large amplification is required due to deterioration of the electric field (but there is no limit), the electronic device 101 requires a higher transmission power than the transmission power that the second power amplifier (403 in FIGS. 4B and 5B) can output.
