Abstract
A (RF) switching system for minimizing received signal leakage during switching including a plurality of band filters comprising a first band filter, a second band filter, and a third band filter, first and a second antenna, and a switch configured to selectively couple the first, second and third filters to the first and second antennas and configured to receive complementary control signals, wherein at least the first and the second filter are configured to be simultaneously coupled to the first antenna and the switch is further configured to delay at least one of the complementary control signals when the switch, in response to the complementary control signals, is configured to selectively connect the first antenna to the third filter instead of the second filter while the first filter is coupled to the first antenna and a first communication path through the first filter to the first antenna is active.
