Radio-frequency switch circuit |
摘要 |
A radio-frequency switch circuit of the invention includes: n-stage through FETs (field effect transistors) connected in series between the antenna terminal and each of the radio-frequency terminals, where n is a natural number; a radio-frequency leakage prevention resistor connected to a gate of the through FETs; a control signal line commonly connected to the gates of the n-stage through FETs connected to the same radio-frequency terminal; and a resistor connected to each of at least two of the control signal lines and connected to the radio-frequency leakage prevention resistor in series The two control signal lines are capacitively coupled between the resistor and the through FETs. |
