Abstract
An improved radio frequency (RF) switch circuit is disclosed. The RF switch is typically used in a communication system having one or more transmission paths and one or more reception paths. The RF switch has a first set of diodes connected in parallel among themselves, and a second set of diodes connected in parallel among themselves. Each diode of the second set is coupled with at least one predetermined diode in the first set in a parallel manner by sharing a connection node that is coupled further with at least one antenna. A transmitter is coupled to the first set of diodes and the receiver is separately coupled to the second set of diodes, wherein either one of the first set of diodes or the second set of diodes are activated to establish one path while cutting off all other paths at the same time.
