Abstract
RF circuitry, which includes a first main RF switching circuit and a second main RF switching circuit, is disclosed. The first main RF switching circuit is capable of providing an RF signal path between a first main RF port and a first selected one of a first RF antenna and a second RF antenna. The second main RF switching circuit is capable of providing an RF signal path between a second main RF port and a second selected one of the first RF antenna and the second RF antenna. The first main RF switching circuit includes a first pair of RF switches coupled in series between the first RF antenna and the first main RF port; a second pair of RF switches coupled in series between the second RF antenna and the first main RF port; a first shunt RF switch; and a second shunt RF switch.
