Patent attributes
Described herein are systems, devices, and methods for front end configurations that support multiple input multiple output (MiMo) communication for cellular 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 low-band (LB) cellular frequency bands and the second multiplexer processes mid-band (MB), high-band (HB), and ultra high-band (UHB) cellular frequency bands. Each frequency band includes a duplexer to enable bi-directional communication.
