Abstract
A radio frequency (RF) amplifier has a first transistor with a first gate coupled to a first input, and a first series-connected capacitor-resistor combination coupled between the first gate and a first source. A first shunt switch is in parallel with the first resistor and controlled by a first signal. A grounding switch is between the first gate and ground, controlled by a second signal. A controller commands the switches to select an on-state for amplification at the first input or off-state to prevent RF signal amplification. A second transistor with a second gate is coupled to a second input, and a second series-connected capacitor-resistor combination is coupled between the second gate and a second source. A second shunt switch is in parallel with the second resistor and controlled by a third signal. A grounding switch is between the first gate and ground and is controlled by a fourth signal.
