Apparatus and methods for radio frequency PIN diode switches
Apparatus and methods for radio frequency (RF) PIN diode switches are provided herein. In certain configurations, one or more PIN diode switches are integrated with a driver chip in a common package. The driver chip includes voltage regulators, such as switching regulators and/or charge pumps configured to generate voltage levels used to control biasing of the PIN diode switches. Thus, the packaged switch can operate using a single power supply voltage, which the voltage regulators of the driver chip use to generate biasing voltage levels used for controlling the PIN diode switches.
