Abstract: A wearable electronic device is provided. The wearable electronic device includes a housing, a display disposed on a first surface of the housing, a rear plate disposed on a second surface of the housing opposite the first surface, and a sensor module disposed in the housing. The rear plate includes a first rear plate including insert areas, a second rear plate configured to surround at least a part of the first rear plate, and cover members disposed to close the insert areas. The sensor module includes at least one optical sensor and at least one temperature sensor disposed in spaces surrounded by the insert areas and the cover members. A first coating area including at least one of a thermal conductive coating layer or a light-blocking coating layer is formed on at least a part of at least one of side surfaces of the insert areas.

Abstract: A radio-frequency (RF) circuit is provided. The RF circuit includes: a power amplifier; a predistortion circuit configured to predistort an input signal based on reference predistortion information to obtain a predistortion signal, and output the predistortion signal to the power amplifier; and a gain circuit configured to provide a gain, corresponding to a reciprocal of a nonlinear coefficient of the power amplifier, to the predistortion circuit.
