Mobile wireless communications device with DDPDT RF switch and related methods

A mobile wireless communications device comprising:

• an antenna;
• a plurality of primary radio frequency (RF) receivers configured to operate at a plurality of different RF bands, each primary RF receiver having a differential input;
• a plurality of secondary RF receivers also configured to operate at the plurality of different RF bands, each secondary RF receiver having a differential input;
• first and second RF filters coupled to said antenna and configured to respectively pass first and second RF bands from among the plurality of different RF bands;
• a first differential double-pole, double-throw (DDPDT) RF switch coupled between said first and second RF filters and the differential inputs of respective first ones of said pluralities of primary and secondary RF receivers;
• third and fourth RF filters coupled to said antenna and configured to respectively pass third and fourth RF bands from among the plurality of different RF bands;
• a second DDPDT RF switch coupled between said third and fourth RF filters and the differential inputs of respective second ones of said pluralities of primary and secondary RF receivers;
• and
• a housing containing said antenna, said first, second, third, and fourth RF filters, said pluralities of primary and secondary RF receivers, and said first and second DDPDT RF switches.
