Bi-directional communication for cellular and wireless local area network frequency bands

Abstract:

Described herein are systems, devices, and methods for front end configurations that support bi-directional communication for cellular and wireless local area network signals. The configurations include an antenna triplexer, a first multiplexer, and a second multiplexer. A first filter of the triplexer is coupled to a signal port of the first multiplexer, a second filter of the triplexer is coupled to a first signal port of the second multiplexer, and a third filter of the triplexer is coupled to a second signal port of the second multiplexer. The first multiplexer processes cellular frequency bands and the second multiplexer processes cellular frequency bands and wireless local area network signals. Each frequency band includes a duplexer to enable bi-directional communication.
