摘要: An electronic device is provided. The electronic device includes a digital pre-distortion (DPD), a digital-to-analog converter (DAC), a power amplifier (PA), a first coupler obtaining a feedback signal from an output of the power amplifier, a circulator obtaining a reverse signal in which the output of the power amplifier is reflected, a transmission filter, a second coupler obtaining a filter-feedback signal from an output of the transmission filter, an antenna, an analog-to-digital converter (ADC) converting a composite signal including the feedback signal, the filter-feedback signal, and the reverse signal into a digital composite signal, a separation circuit, and a pulse inter-modulation cancellation (PIMC) circuit in which the separation circuit, based on the digital composite signal and an input signal of the DPD, obtains a digital signal of the feedback signal, a digital signal of the filter-feedback signal, and a digital signal of the reverse signal.

摘要: According to various embodiments, an electronic device may comprise: a communication circuit which comprises a first antenna component and a second antenna component to determine a first value through the first antenna component and determine a second value through the second antenna component; a processor; and at least one memory, wherein the at least one memory has instructions stored therein which cause, when executed, the processor to: determine whether a first module disposed in the vicinity of the first antenna component has started operating; compensatively adjust a first value obtained during the operation of the first module, by using a first value obtained before the operation of the first module or a second value obtained during the operation of the first module, in response to the determination as to whether the first module has started operating; and operate the communication circuit according to a first value obtained by the compensation, wherein the first value obtained during the operation of the first module may contain a first noise value resulting from the operation of the first module. Various other embodiments are also possible.

摘要: An electronic device including a shielding structure is provided. The electronic device includes a housing, a first board disposed in an inner space of the housing and including a first electrical element and a first ground layer, a second board disposed in the inner space to be spaced apart from the first board and including a second electrical element, and an interposer disposed between the first board and the second board so as to electrically connect the first board and the second board to each other. The second board includes a first surface facing the first board, a second surface facing away from the first surface, insulating layers disposed between the first surface and the second surface, first slits formed at a predetermined interval in a first conductive area disposed in a first insulating layer among the insulating layers, and second slits formed at a predetermined interval in a second conductive area disposed in a second insulating layer between the first insulating layer and the second surface. The first slits are disposed at a position where the plurality of first slits do not overlap the plurality of second slits in case the second board is viewed from above.
