Abstract: A radio frequency (RF) device and a voltage generation and harmonic suppressor thereof are provided. The RF device includes the voltage generation and harmonic suppressor and a RF circuit. The voltage generation and harmonic suppressor is configured to receive a RF signal to output at least one direct current (DC) voltage related to the RF signal, and configured to suppress a harmonic generated by the RF signal in the voltage generation and harmonic suppressor. The RF circuit is configured to receive the RF signal, and configured to perform an operation according to the at least one DC voltage.

Abstract: A radio frequency switch has an antenna end, a first signal end for transmitting a first radio frequency signal, a second signal end for transmitting a second radio frequency signal, a third signal end for transmitting a third radio frequency signal, a first series path having a first switch, a second series path having a second switch, a third series path having a third switch, a first shunt path coupled between the first signal end and a node, a second shunt path coupled between the second signal end and the node, a common path coupled between the node and a first reference voltage end, and a third shunt path coupled between the third signal end and a second reference voltage end. The first series path and the second series path are connected to a common ground pad via the common path.
