Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as Long-Term Evolution (LTE). The present disclosure provides a device for variable signal attenuation equipped in a stack-up structure inside an RFIC. The device for signal attenuation comprises: a first transmission line positioned on a first layer inside the RFIC; a second transmission line positioned on a second layer, which is adjacent to the first layer, and electromagnetically coupled to the first transmission line; and a control unit. The first transmission line comprises an impedance control unit on one side. The control unit can variably control the impedance control unit.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An electronic device and an operation method thereof are provided for testing performance of a radio frequency integrated circuit (RFIC) in a wireless communication system. The method includes checking a connection state of elements operable as combiners and a plurality of RF chains of the RFIC; performing control to output RF signals from the plurality of RF chains; acquiring an integrated signal by combining the RF signals via the combiners; and determining a quality indicator for the RFIC based the integrated signal.
