Publication number: 20240080002Abstract: A low-noise amplifier in a receiver supporting a beam forming function may selectively change a phase shift for beam steering. The low-noise amplifier may include first and second transistors and a variable capacitance circuit connected to a gate of the second transistor. The variable capacitance circuit may selectively change capacitance thereof based on a capacitance control signal applied thereto according to beam-forming information, where the changed capacitance correspondingly causes a phase change in an output signal of the low-noise amplifier. A similar scheme may be employed for amplifiers in transmit signal paths to steer a transmit beam.Type: ApplicationFiled: November 6, 2023Publication date: March 7, 2024Inventors: Young-min Kim, Jae-seung Lee, Jung-seok Lim, Pil-sung Jang
