Circuitry includes an antenna node, a number of input/output nodes, radio frequency (RF) multiplexer circuitry, and bypass circuitry. The RF multiplexer circuitry is coupled between the input/output nodes and the antenna node. The bypass circuitry is coupled to the input/output nodes and the antenna node. The bypass circuitry is configured to, in each uplink time slot of a TDD frame, couple one of the input/output nodes directly to the antenna node such that the RF multiplexer circuitry is bypassed. Further, the bypass circuitry is configured to, in each downlink time slot of the TDD frame, couple each one of the input/output nodes to the antenna node via the RF multiplexer circuitry.
