SIGNAL SWITCHING SYSTEMS AND ELECTRONIC DEVICES USING SAME

Abstract:

An example of a signal switch includes a first transistor coupled between first and second nodes, a plurality of second transistors coupled in series between the first and second nodes, in parallel with the first transistor, a third transistor coupled between the first node and a third node, and a plurality of fourth transistors coupled in series between the first and third nodes, in parallel with the third transistor. The signal switch further includes a first shunt path including a first shunt transistor and a first inductor connected in series between a reference node and a first connection point between two of the plurality of second transistors, and a second shunt path including a second shunt transistor and a second inductor connected in series between the reference node and a second connection point between two of the plurality of fourth transistors.
