    Abstract: A wireless modem device. The device includes a plurality of transceivers, a plurality of antenna ports, a plurality of RF multiplexers, and a plurality of switches. Each transceiver is configured to process a radio frequency (RF) signal in a specific frequency band. Each antenna port is coupled to one of a plurality of antennas. Each RF multiplexer is configured to split an RF signal received via a common port of the RF multiplexer to one of frequency-specific ports of the RF multiplexer based on a frequency band of the RF signal and combine RF signals received via the frequency-specific ports into the common port, wherein the common port of each RF multiplexer is coupled to one of the antenna ports. Each switch is configurable by software to couple one of the transceivers to one of the antenna ports.
