A mobile wireless communications device may include an antenna, a wireless radio frequency (RF) receiver, a wireless RF transmitter, and a duplexer connecting the wireless RF receiver and the wireless RF transmitter to the antenna. More particularly, the wireless RF receiver may include a low noise amplifier (LNA) connected to the duplexer, a first receive signal chain for wireless communications signals having a first signal type downstream from the LNA, a second receive signal chain for wireless communications signals having a second signal type different than the first frequency band downstream from the LNA, and a power divider connecting the LNA to the first and second receive signal chains.
