Abstract:
A radio frequency (RF) switch die which includes an antenna port, a plurality of RF ports, a switch fabric for selectively coupling one or more of the RF ports to the antenna port, and control circuitry that is adapted to, in a first mode, direct the switch fabric to couple any one of the plurality of RF ports individually to the antenna port, and in a second mode, couple a selected group of the RF ports to the antenna port. The RF switch die may include M number of RF ports, and be relatively easily reconfigured to provide N number of RF ports, wherein N is less than M. Groups of RF ports may be coupled together to form coupled RF ports that offer different electrical characteristics than non-coupled RF ports.
