Patent number: 11955997Abstract: An antenna module includes a multilayer board, a radio frequency (RF) chip, and a active device array. The multilayer board includes an antenna that transmits and receives electromagnetic waves through a top surface of the multilayer board. The RF chip, on a bottom surface of the multilayer board, is connected to the antenna and processes an RF signal. The active device array, on the bottom surface of the multilayer board, includes active devices, a first input pin and a first output pin. The first input pin and the first output pin are respectively connected to electrodes of an active device of the active devices. The multilayer board includes a first pattern for a first signal to be provided from the RF chip to the first input pin, and a second pattern for a second signal to be provided from the first output pin to the RF chip.Type: GrantFiled: July 19, 2021Date of Patent: April 9, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Youngmin Kim, Hongjong Park, Daeyoung Yoon, Sunwoo Lee, Youngki Lee, Dooseok Choi

Patent number: 11863226Abstract: The present disclosure provides a communication device and an operating method. The communication device includes an antenna, a transmission processor, a radio frequency chain, and a reception processor. The transmission processor is configured to output a second transmission input signal with the same average power as the average power of a first transmission input signal and a second amplitude greater than a first amplitude of the first transmission input signal. The RF chain is configured to output an RF output signal to be transmitted through the antenna, based on a transmission input signal, and to output a reception input signal based on a signal received through the antenna. The reception processor is configured to check an out-of-band blocker by detecting a peaked frequency spectrum based on the reception input signal and to adjust a reception characteristic parameter of the RF chain based on an amplitude of the peaked frequency spectrum.Type: GrantFiled: April 28, 2022Date of Patent: January 2, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Youngmin Kim, Hongjong Park, Iljin Lee
