RADIO FREQUENCY SWITCH CIRCUIT

摘要

A radio frequency switch circuit, according to examples, includes a switching circuit controlled to be in a turned on or turned off state on the basis of a gate signal to thereby allow a radio frequency signal to pass or be blocked; a voltage dividing circuit connected to terminals of the switching circuit that the radio frequency signal passes through and outputting intermediate voltage between the terminals by a voltage dividing node; and an impedance circuit connected between the voltage dividing node and a body terminal of the switching circuit.

1. A radio frequency switch circuit, comprising a first switch circuit connected between a signal port and an antenna port and operated by a gate signal, wherein the first switch circuit comprises:
a switching circuit controlled to be in a turned on or turned off state on the basis of the gate signal to thereby allow a radio frequency signal to pass or be blocked; a voltage dividing circuit connected to terminals of the switching unit that the radio frequency signal passes through and configured to output intermediate voltage between the terminals by a voltage dividing node; and an impedance circuit connected between the voltage dividing node and a body terminal of the switching circuit.
