Abstract

A device for supporting wireless communication is provided. The device includes a transceiver, an antenna, and a radio frequency (RF) front end system communicatively coupled to the transceiver and the antenna. The RF front end system may include: a RF sampling block coupled to the transceiver and configured to sample signals received from the transceiver and output voltage signals; a RF switching logic coupled to the RF sampling block to receive the voltage signals and configured to switch the front end RF system between a transmitting mode and a receiving mode; a RF transmission gain block coupled to the RF switching logic and configured to increase a transmission power of the signals received from the transceiver; and a RF receiving gain block coupled to the RF switching logic and configured to remove noise signals contained in radio frequency signals received from the antenna.
