    摘要: Various embodiments of the present invention relate to a method for inspecting whether an electronic device and a communication device included in the electronic device operate normally. A method for checking characteristics of a wireless communication device, according to various embodiments of the present invention, comprises the steps of: providing a wireless communication device at a first location, wherein the wireless communication device includes an antenna array and a wireless communication circuit electrically connected to the antenna array, and the wireless communication circuit is configured to transmit and receive signals having frequencies of 20 Ghz to 100 Ghz and includes a plurality of phase shifters configured to adjust phases of the signals in order to form directional beams together; providing a signal detecting device at a second location separated from the first location so as to detect a wireless signal from the wireless communication device; allowing the wireless communication device to transmit a first signal in a state in which all the phase shifters are configured to have a first delay; detecting a first power of the first signal by using the signal detecting device; allowing the wireless communication device to transmit a second signal in a state in which all the phase shifters are configured to have a second delay; and detecting a second power of the second signal by using the signal detecting device.

    摘要: An electronic device and method thereof of are provided to prevent burnout due to overcurrent. An electronic device includes a power amplifier configured to amplify a transmission signal; a battery configured to provide a bias voltage to the at least one power amplifier; and an overcurrent protection circuit configured to prevent overcurrent from flowing through the power amplifier. The overcurrent protection circuit includes a configurer configured to configure a reference current value, based on the power amplifier; a measurer configured to measure a bias current value due to the bias voltage; a comparator configured to compare the measured bias current value with the reference current value; and a controller configured to recognize overcurrent flowing through the power amplifier and control provision of the bias voltage, based on a result of the comparison.
