Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A low noise amplifier (LNA) in a wireless communication system according to an embodiment of the disclosure includes a first transistor and a first feedback transformer in which a gate of the first transistor is connected to a primary coil of the first feedback transformer and a source of the first transistor is connected to a secondary coil of the first feedback transformer. The first feedback transformer is configured to implement positive feedback to maintain an in-phase signal at the gate of the first transistor and the source of the first transistor.

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.
