Abstract: A switch assembly for a radio frequency signal and corresponding radio frequency module and wireless device is disclosed. An example switch assembly comprises a first node coupled to an input of the switch assembly, a second node coupled to an output of the switch assembly, a first control node, and a common node; a first switch having a first plurality of transistors coupled between the first and second nodes, each transistor of the first plurality of transistors having a gate, a drain, and a source, each gate of the first plurality of transistors being coupled to the common node; a common resistor coupled between the first control node and the common node; and a second switch coupled between the first control node and the common node in parallel to the common resistor, the second switch configured to selectively bypass the common resistor.

Abstract: Various implementations include circuits, devices and/or methods that provide open loop current limiting power amplifiers and the like. In some implementations, an open loop current clamp includes a trim module to provide a control value and a limiting source having respective input and output terminals. The input terminal is coupled to the trim module to receive the control value. The output terminal coupled to a control terminal of the first transistor to provide a limiting electrical level produced in response to the control value by the limiting source. The limiting electrical level substantially setting a first mode of operation for the first transistor such that the current draw of the first transistor is substantially determined by the first mode of operation and the limiting electrical level such that a voltage at an output terminal of the first transistor exerts reduced influence on the current draw.
