Abstract
A single-pole multi-throw switch includes a set of selection switches. The set of selection switches includes a set of primary switches, a first set and a second set of secondary switches. The primary set of switches includes a plurality of primary transistors coupled in series for transmitting radio frequency signals. The first set of secondary switches is coupled to the primary set of switches and includes a plurality of first secondary transistors coupled in series for transmitting the radio frequency signals when the primary transistors and the first secondary transistors are turned on. The second set of secondary switches is coupled to the primary set of switches and includes a plurality of second secondary transistors coupled in series for transmitting the radio frequency signals when the primary transistors and the second secondary transistors are turned on.
