Zusammenfassung:A mobile wireless communications device (10) may include an antenna (12), LTE RF differential inputs (18a-18f), and a front end circuit (21-23). The front end circuit may include band pass filters (24a-24b, 31a-31b, 44a-44b) coupled to the antenna, LNAs (25a-25b, 32a-32b, 43a-43b) coupled respectively to the band pass filters, and RF switching circuits (26a-26b, 33a-33b, 42a-42b). Each RF switching circuit may be respectively coupled between each LNA and a pair of LTE RF differential inputs (18a-18b) and configured to switch to one or both of the pair of LTE RF differential inputs.
