OPTIMIZED GATE AND/OR BODY BIAS NETWORK OF A RF SWITCH FET

Abstract:

A radio frequency signal switch assembly including a signal input and a signal output, a first control input configured to receive a control signal, a first switch including a first plurality of transistors coupled between the signal input and the signal output, each transistor of the first plurality of transistors having a gate, a drain, and a source, a first common resistor coupled between the first control input and the gate of one transistor of the first plurality of transistors, and a first plurality of gate resistors coupled between the gates of the first plurality of transistors, each gate resistor being coupled between the gates of two adjacent transistors.
