Abstract

A radio-frequency switch includes a first series switch including a plurality of series field-effect transistors (FETs) connected in series between a first terminal and a second terminal, a first shunt switch including a plurality of shunt FETs connected in series between the first terminal and a first ground terminal, and a first shunt gate resistor circuit including a plurality of gate resistors respectively connected to gates of the plurality of shunt FETs of the first shunt switch. Respective resistance values of the plurality of gate resistors of the first shunt gate resistor circuit successively increase in a direction away from the first ground terminal toward the first terminal.
