Abstract
A radio frequency switch system includes a plurality of radio frequency switch circuitries that each include a switch branch coupled between a first branch terminal and a second branch terminal and are configured to allow passage of a radio frequency signal through the switch branch in an on-state and to block the radio frequency signal from passing through the switch branch in an off-state in response to a control signal applied to a branch control terminal of the switch branch. Also included is a switch controller configured to apply the control signal to the branch control terminal of the switch branch of each of the plurality of radio frequency switch circuitries, wherein the control signal has a first voltage level that places the switch branch in the on-state and a second voltage level that places the switch branch in the off-state without digital signal decoding of the control signal.
