Abstract
Embodiments of the invention relate to a circuit assembly for biasing a PIN diode, wherein a DC biasing voltage is obtained by extracting power from a radio-frequency transmission path. The circuit assembly comprises a PIN diode, an input node configured to receive a radio-frequency input voltage, a rectifying circuit configured to receive the radio-frequency input voltage from the input node and generate a rectified voltage, and a smoothing circuit configured to receive the rectified voltage from the rectifying circuit and generate a DC voltage. The output of the smoothing circuit forms the input to the PIN diode to reverse-bias the diode. Related methods, radio-frequency switching circuits and radio-frequency modules are also provided.
