Abstract
An apparatus is disclosed for time-division duplex dynamic transceiver isolation. In an example aspect, the apparatus includes an antenna, a power amplifier circuit including at least one power-amplifying path, a low-noise amplifier, and a time-division duplex interface circuit. The interface includes at least one transmit node coupled to the at least one power-amplifying path, a receive node coupled to the low-noise amplifier, and an antenna node. The antenna node is coupled to the at least one transmit node, the receive node, and the antenna. The interface circuit is configured to connect the at least one transmit node, the receive node, and the antenna node together at both a first time and a second time. The interface circuit is configured to isolate the receive node from the antenna node at the first time and isolate the at least one transmit node from the antenna node at the second time.
