Patent ID: 11963112
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electronic device comprising:
an amplification circuit;
an antenna configured to be electrically connected to the amplification circuit;
a variable element configured to adjust an impedance between the amplification circuit and the antenna; and
a control circuit,
wherein the control circuit is configured to:
output a signal amplified by a designated gain using the amplification circuit to an external electronic device using the antenna, with the variable element adjusted to a first impedance;
detect that an external object is adjacent while outputting the signal;
identify a tuning code for changing the first impedance of the variable element to a second impedance upon detecting that the external object is adjacent;
adjust the designated gain based on a first power adjustment value when the tuning code belongs to a first group; and
refrain from adjusting the designated gain when the tuning code belongs to a second group.
