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 &#x2212;20 volts may be generated.

Integrated solution for multi-voltage generation with thermal protection

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 &#x2212;20 volts are generated. The drive circuitry can operate from a single, low-voltage power source.

Programmable biasing for pin diode drivers

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.

Integrated biasing for pin diode drivers

A switching circuit includes a first diode coupled between a first terminal and a second terminal, a second diode coupled between the first terminal and a third terminal, and a bias circuit coupled to the first terminal and configured to bias the first diode on and the second diode off in a first switch state and to bias the first diode off and the second diode on in a second switch state, the bias circuit including a voltage converter configured to convert a fixed voltage to an intermediate voltage and a current source coupled in series with the voltage converter.
