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.

Abstract: A communication device includes: a transmission line; a first circuit communicatively coupled to the transmission line and configured to receive an outbound signal over the transmission line, the first circuit comprising an amplifier configured to amplify the outbound signal to form an amplified signal, the first circuit being configured to transmit a first portion of the amplified signal to an antenna element; and a second circuit communicatively coupled to the transmission line and configured to produce the outbound signal and to transmit the outbound signal over the transmission line, the second circuit further being at least one of configured to transmit a control signal for the amplifier over the transmission line or configured to receive a feedback signal, based on the amplified signal, over the transmission line such that the outbound signal and at least one of the control signal or the feedback signal concurrently share the transmission line.
