Abstract:
A method includes providing a radio frequency front end (RFFE) switch including a single pole input terminal and a number (N) of output terminals. Each of the N output terminals is a component of a respective one of N throws of the RFFE switch, with N being greater than one. The N output terminals include a first output terminal corresponding to a first throw of the N throws and at least one additional output terminal not connected to any radio frequency (RF) band path. The at least one additional output terminal includes a second output terminal corresponding to a second throw of the N throws. The method includes connecting the first output terminal to a single RF band path. The method includes forming a parallel connection between the single pole input terminal and the single RF band path. The parallel connection provides at least two parallel branches for routing RF signals being transceived between the single pole input terminal and the single RF band path.
