Abstract
The present disclosure relates to a single pole double throw, SPDT, radio frequency, RF, switch topology including a first port, a second port, and a third port. A first switchable path is arranged between the first port and the second port and includes at least one first switching stage and at least one second switching stage. A second switchable path is arranged between the first port and the third port and includes at least one first switching stage and at least one second switching stage. Each first switching stage includes a first impedance network having a line inductance element and two shunt capacitors, the first switching stage further including at least one shunt PIN diode and a bias feed for applying a bias voltage to the at least one shunt PIN diode, wherein the two shunt capacitors of each first switching stage are grounded via the at least one shunt PIN diode.
