Abstract
A radio frequency front end of a user equipment for reducing power consumption includes a receive chain having a first low noise amplifier stage, a transmit chain including a first power amplifier stage, a transmit bypass path, a receive bypass path and a time division duplex switch. The transmit bypass path is selectively coupled to a transmit signal path at a first intermediate point of the transmit chain, prior to the first power amplifier stage. The receive bypass path is selectively coupled to a receive signal path at a first intermediate point of the receive chain after the first low noise amplifier stage. The time division duplex switch is selectively coupled to an antenna, the transmit bypass path, the receive bypass path, the first power amplifier stage and the first low noise amplifier stage.
