MOBILE DEVICE, FRONT-END SIGNAL PROCESSING METHOD ON MOBILE DEVICE, DIVERSITY MODULE FOR MOBILE DEVICE AND SIGNAL PROCESSING METHOD ON DIVERSITY MODULE

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and methods for multi-band RF signal routing.SOLUTION: In a certain configuration, a mobile device includes an antenna switch module, a diversity module, and one or more diversity antennas. The diversity module is electrically coupled to the one or more diversity antennas, and processes diversity signals received on the one or more diversity antennas to generate a high band (HB) signal, a mid band (MB) signal, and a low band (LB) signal. Additionally, the diversity module generates a combined LB/HB signal on the basis of combination of the LB signal and the HB signal, and provides the MB signal and the combined LB/HB signal to the antenna switch module.
