Apparatus and methods for PIN diode switches for radio frequency electronic systems
Apparatus and methods for PIN diode switches for radio frequency electronic systems are provided herein. In certain configurations, a packaged switch including a packaging substrate including a die paddle and a thermally conductive substrate attached to the die paddle, one or more PIN diode switches attached to the thermally conductive substrate, and a driver chip attached to the die paddle and configured to generate a plurality of bias voltages operable to control biasing of the one or more PIN diode switches. The driver chip includes a switching regulator configured to generate a first bias voltage of the plurality of bias voltages and a charge pump configured to generate a second bias voltage of the plurality of bias voltages.
