摘要： A mobile wireless communications device may include an antenna, LTE RF differential inputs, and a front end circuit. The front end circuit may include band pass filters coupled to the antenna, LNAs coupled respectively to the band pass filters, and RF switching circuits. Each RF switching circuit may be respectively coupled between each LNA and a pair of LTE RF differential inputs and configured to switch to one or both of the pair of LTE RF differential inputs.
