Abstract: An apparatus configured to transmit and receive a radio frequency (RF) signal is provided. The apparatus includes a digital-to-analog converter (DAC) configured to convert a digital signal into an analog signal, a power amplifier configured to amplify the analog signal, and an antenna configured to output, as the RF signal, the amplified analog signal to the outside. The DAC includes a current cell matrix including a plurality of current cells configured to generate the analog signal, a plurality of normal paths configured to control the plurality of current cells to be turned on or off, based on the digital signal, and a plurality of alternative paths configured to selectively consume power, based on a pattern of the digital signal.

Abstract: An electronic device according to various embodiments of the disclosure may include a housing including a first plate forming an outer face. The first plate may include a glass plate including a first surface outwardly facing the housing and a second surface inwardly facing the housing, a coating layer including an anti-reflection coating and/or an anti-finger coating above the first surface while forming the outer face, a first layer formed between the first surface of the first glass plate and the coating layer, having a first thickness, and including a first inorganic material, a second layer formed between the first layer and the coating layer, having a second thickness, and including a second inorganic material different from the first inorganic material, a third layer formed between the second layer and the coating layer, having a third thickness thicker than each of the first thickness and the second thickness, and including a third inorganic material, and an opaque layer formed on the second surface. Various other embodiments may also be possible.
