A power amplifier system which operates at a narrow band with high power and high efficiency or at a wide band is provided. Said power amplifier system comprises at least one high power amplifier; at least one connection line; at least one input block which receives at least one signal from an input, which is connected to said high power amplifier and connection line, which sends received signal to either high power amplifier or connection line and which amplifies the power of the signal sent to the connection line; and at least one high power asymmetric output switch, which is connected to said high power amplifier and connection line and which sends signals coming from said high power amplifier and connection line to an output.

Power amplifier system

An active limiting system that is suitable to protect a low noise amplifier against the high power signals received from a signal input includes, at least one first switch, source of which is connected to a gate voltage; at least first resistor which is connected between the gate and source of the first switch; at least one second resistor, which is connected between a drain voltage and drain of the first switch; at least one second switch, source of which is connected to said drain voltage and drain of which is connected to a signal input; at least one third resistor which is connected between the drain of the first switch and gate of the second switch; at least one first filtering element, which blocks DC currents/voltages and which is connected between the source of the second switch and ground.
