Abstract
A signal switching arrangement includes first and second switches coupled between a signal input terminal and a signal output terminal. A bias signal for causing the first switch to couple an input signal to the second switch is applied to the output terminal. The second switch is controlled by a control signal to selectively couple the bias signal to the first switch, thereby causing the input signal to be coupled to the output terminal through both switches. The arrangement is particularly well suited to form a relatively inexpensive signal multiplexer with good isolation characteristics.
