Abstract: A millimeter wave module inspection system includes: an electronic device including at least one processor; and a millimeter wave module including a memory, at least one antenna, and at least one transceiver, wherein the at least one processor is configured to: control an input signal to be input to a transmission signal input terminal of the millimeter wave module; identify an output signal that is output from a reception signal output terminal of the millimeter wave module when the input signal passes through the at least one antenna of the millimeter wave module; identify first data corresponding to a transmission chain gain related to a transmission path of the millimeter wave module stored in the memory and second data corresponding to a reception chain gain related to a reception path of the millimeter wave module, the first data and the second data being stored in the memory; and determine whether the millimeter wave module is abnormal based at least on the identified output signal, the first data, and the second data.

Abstract: 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.

Abstract: An apparatus and a method are provided for, in an electronic device which generates a reference signal having a reference frequency, mixes the reference signal to an input signal for transmission, and amplifies power, outputting a control signal for turning off amplifying the power, if a frequency of a signal acquired at an arbitrary point after generating the reference signal or mixing the signals before amplifying the power is out of a designated frequency band, thus preventing burnout of a power amplifier.
