Abstract:
A device includes multiple transceivers, a coupling block and an antenna. The transceivers operate according to time-division multiple access (TDMA) techniques. The coupling block is designed to enable the multiple transceivers to transmit or receive corresponding signals using the antenna. The multiple transceivers include a first transmitter and a second transmitter. The first transmitter is connected to the antenna via a first coupling network. The second transmitter is connected to the antenna via a series connection of a second coupling network and at least a portion of the first coupling network. Other transmitters are connected to the antenna via a series arrangement of at least a portion of the first coupling network and corresponding coupling networks.
