Abstract: A communication device configured to transmit/receive a radio frequency (RF) signal is provided. The device includes a transceiver including an amplifier device using a multi-loop inter-stage matching (ISM) transformer, and a processor configured to control an operation of the amplifier based on a signal strength during transmission/reception of the RF signal. The transformer is disposed between a first amplifier and a second amplifier and includes a plurality of primary loops and a plurality of secondary loops, each primary loop includes an inductor component having a different size and a different Q-factor and each secondary loop includes an inductor component having a different size and a different Q-factor. The processor adjusts an attenuation level of the transformer by controlling a switching connection to the first amplifier and the second amplifier for one primary loop among the plurality of primary loops and one secondary loop among the plurality of secondary loops.
