Abstract: A multi-voltage converter is described that includes integrated temperature-protection circuitry. The converter may be used to bias radio-frequency components such as PIN diodes and gallium-nitride devices, and may include integrated bias-sequencing circuitry. Programmable output voltages as high as 30 volts and as low as ?20 volts may be generated.

Abstract: Driving circuitry is described that includes multiple programmable bias voltages useful for biasing radio-frequency components such as PIN diodes and gallium-nitride devices. Programmable voltages as high as 30 volts and as low as ?20 volts are generated. The drive circuitry can operate from a single, low-voltage power source.

Abstract: Radio-frequency signals may be switched between signal lines or signal ports in RF circuits using PIN diodes and PIN-diode driving circuitry. To achieve switching, the PIN diodes are biased at voltages as high as 20 volts or more. Circuitry for biasing PIN diodes is described that uses a low-voltage power source and a single-bit control line.
