FIG. 4 is a flowchart 400 embodying the operation of FIG. 3 according to an embodiment of the present disclosure.

Referring to FIG. 4, a processor (e.g., processor 220 of FIG. 2) of an electronic device (e.g., electronic device 201 of FIG. 2) transmits a wireless signal to a transceiver (e.g., transceiver of FIG. 2) in operation 410. 225)) through the first amplification circuit (e.g., the first amplification circuit 247 in FIG. 2) to the second amplification circuit (e.g., the wireless signal processing circuit 270 in FIG. 2). It can be transmitted to the second amplifier circuit 271 in FIG. 2. For example, the transceiver 225 up-converts a signal (e.g., a baseband signal or an intermediate frequency band signal) generated by the processor 220 into a wireless signal in a designated frequency band, and operates the first amplification circuit 247. It can be transmitted to the second amplification circuit 271 of the wireless signal processing circuit 270.

In one embodiment, the processor 220 couples the wireless signal transmitted to the second amplification circuit 271 of the wireless signal processing circuit 270 with a coupler (e.g., the first coupler 255 in FIG. 2) in operation 420. It can be detected through For example, the coupler 255 may be disposed between the first amplification circuit 247 of the transceiver 225 and the second amplification circuit 271 of the wireless signal processing circuit 270.

In one embodiment, the coupler 255 is disposed between the first amplification circuit 247 of the transceiver 225 and the second amplification circuit 271 of the wireless signal processing circuit 270, such that the A wireless signal transmitted to the second amplification circuit 271 of the wireless signal processing circuit 270 can be detected through the first amplification circuit 247.

In various embodiments, operation 420 may be performed at designated intervals. For example, the above-described operation 420 may be performed at a designated period within a range that does not interfere with the operation of the second coupler 277. For example, the second coupler 277 detects the transmission power of the wireless signal in the process of calibrating the antenna 210, changes the level of the transmission power of the wireless signal, and/or It may operate to detect power reflected from the antenna 210 to adjust the phase.

This may be an operation to check whether it is the same as the signal. In one embodiment, the first frequency band may be a frequency band used to transmit wireless signals.

In one embodiment, if the down-converted wireless signal is included in the first frequency band (e.g., an in-band channel) (e.g., YES in operation 450), the processor 220 branches to operation 410. Thus, the operation of transmitting a wireless signal to the second amplification circuit 271 of the wireless signal processing circuit 270 through the first amplification circuit 247 of the transceiver 255 can be continuously performed. For example, when the down-converted wireless signal is included in a first frequency band (e.g., an in-band channel), the processor 220 combines the down-converted wireless signal with the wireless signal in the designated frequency band. After confirming that it is the same, operation 410 can be continued.

For example, if the down-converted wireless signal is included in a second frequency band (e.g., an out-of-band channel), the down-converted wireless signal is transmitted in a frequency band other than the designated frequency band. It can be confirmed that it is a wireless signal, and the second amplification circuit 247 can be controlled not to perform an amplification operation. For example, the processor 220 controls the second amplification circuit 271 to be turned off so that the second amplification circuit 271 does not receive the wireless signal transmitted through the first amplification circuit 247. can do. It is not limited to this, and for another example, the processor 220 may not perform an operation to transmit a wireless signal. For another example, the processor 220 controls the first amplification circuit 247 to be in an off state, so that the wireless signal passes through the first amplification circuit 247 of the transceiver 225 to the wireless signal processing circuit ( It is also possible to prevent it from being transmitted to the second amplifier circuit 271 of 270).

By silently resetting the transceiver 225, the transceiver 225 can be initialized within a short period of time without being recognized by the user. For another example, during the development process, the wireless signal is not included in a first frequency band (e.g., an in-band channel), and is not included in a second frequency band (e.g., out-of-band channel) excluding the first frequency band. -If it is confirmed to be included in an out-of-band channel, a crash occurs so that malfunction of the transceiver 255 can be confirmed and corrected according to the cause of the malfunction of the transceiver 255. can do.

For example, when the wireless signal is included in the second frequency band (e.g., out-of-band channel), the second amplification circuit 271 of the wireless signal processing circuit 270 Because burnout occurs, the wireless signal is divided into a first frequency band (e.g., an in-band channel) and a second frequency band (e.g., an out-of-band channel). If not included, the processor 220 continues operation 410 of transmitting the wireless signal to the second amplification circuit 271 of the wireless signal processing circuit 270 through the first amplification circuit 247 of the transceiver 255. It can be done by doing this.

3 and 4 according to various embodiments, the wireless signal transmitted from the first amplification circuit 247 of the transceiver 225 to the second amplification circuit 271 of the wireless signal processing circuit 270 is in a designated frequency band. If it is confirmed that the signal is not a wireless signal, the processor 220 may control the second amplification circuit 271 not to perform an amplification operation. Accordingly, the wireless signal transmitted to the second amplifying circuit 271 may not be amplified, and the wireless signal not amplified due to full reflection by a filter (e.g., the filter 273 in FIG. 2) may be amplified by the second amplifying circuit 271. By returning to the amplification circuit 271, it is possible to prevent damage to the second amplification circuit 271 that may occur when a conventional amplified wireless signal is returned.
