Abstract
A single supply RF switch driver. The single supply RF switch driver includes an inverter, where a first resistor has been integrated within the inverter, and the resistor is connected to an RF switch. In one aspect, the integration of the first resistor within the inverter allows for the elimination of a negative power supply for the inverter, while maximizing the isolation achieved in the RF switch. In another aspect, the driver is a configured to have a second resistor integrated within the inverter. A third resistor is connected between the gate of the RF switch and the inverter. In an alternate aspect, the driver operates from a positive power supply and a negative power supply, thus increasing the isolation in the RF switch even further.
