Claim 18:
19. A level shifter for a radio frequency switch, the level shifter comprising:
a first level-shifting n-type transistor;
a first cascode n-type transistor in series with the first level-shifting n-type transistor between a negative charge pump voltage and a first output that provides a first switch control signal;
a first level-shifting p-type transistor;
a first cascode p-type transistor in series with the first level-shifting p-type transistor between a positive charge pump voltage and the first output; and
a second cascode p-type transistor between a regulated voltage and a gate of the first level-shifting n-type transistor and controlled by a first switch enable signal.
