Abstract: A radio frequency (RF) device (100) and its voltage generating circuit (110) are provided. The RF device (100) includes the voltage generating circuit (110) and a RF circuit (120). The voltage generating circuit (110) receives a RF signal (RFC) and generates at least one bias voltage (VB) related to the RF signal (RFC). The RF circuit (120) is used to receive the RF signal (RFC). The RF circuit (120) is coupled to the voltage generating circuit (110) to receive the bias voltage (VB). The bias voltage (VB) is used to operate the conduction state of at least one RF transmission path of the RF circuit (120).
