摘要： Biasing of radio frequency (RF) switches for hot switching is disclosed. In certain implementations, an RF switch includes a first series switching circuit connected between a first pole and a first throw and a second series switching circuit connected between the first pole and a second throw. Additionally, a control circuit controls the first series switching circuit with a first switch control signal and the second series switching circuit with a second switch control signal to provide a transition of the RF switch from a first state in which the first series switching circuit is turned on and second series switching circuit is turned off to a second state in which the first series switching circuit is turned off and the second series switching circuit is turned on. The control circuit turns on the second series switching circuit before turning off the first series switching circuit when providing the transition.
