Abstract: In certain aspects, a system includes a first filter, a second filter, a dummy load, and a switching circuit coupled to the first filter, the second filter, and the dummy load, and coupled to a first antenna and a second antenna. In a first mode, the switching circuit couples the first filter and the second filter to the first antenna, and, in a second mode, the switching circuit couples the first filter and the third filter to the first antenna and couples the second filter to the second antenna. In certain aspects, the dummy load includes a third filter.
