Abstract
A distributed amplifier system constituted of: an input transmission line exhibit a plurality of sections; an output transmission line; an amplifier stage, an output of the amplifier stage coupled to the output transmission line and an input of the amplifier stage coupled to the input transmission line between a respective pair of the plurality of sections; a PIN diode coupled between a first end of the input transmission line and a common potential; and a circuitry coupled between a second end of the input transmission line and the common potential, the second end opposing the first end, such that there is a direct current (DC) flow through the first unidirectional electronic valve, the input transmission line and the circuitry.

A distributed amplifier system comprising:
- an input transmission line exhibiting a plurality of sections;
- an output transmission line;
- an amplifier stage, an output of said amplifier stage coupled to said output transmission line and an input of said amplifier stage coupled to said input transmission line between a respective pair of said plurality of sections;
- a PIN diode coupled between a first end of said input transmission line and a common potential;
- a circuitry comprising a resistor and a capacitor coupled between a second end of said input transmission line and the common potential, said second end opposing said first end, such that there is a direct current (DC) flow through said PIN diode, said input transmission line and said resistor of said circuitry when a signal received at said input transmission line exceeds a predetermined threshold;
- and
- a protection circuitry, said protection circuitry comprising a unidirectional electronic valve coupled between said second end of said input transmission line and the common potential, a polarity of said unidirectional electronic valve opposing a polarity of said PIN diode.
A method of controlling a distributed amplifier system comprising:
- providing a series connection of PIN diode and a resistor coupled between a first end of an input transmission line and a second end of the input transmission line;
- and
- providing a capacitor in parallel with the resistor, such that there is a direct current (DC) flow through said PIN diode, said input transmission line and said provided resistor when a signal received at said input transmission line exceeds a predetermined threshold;
- and
- providing a protection circuitry, said protection circuitry comprising a unidirectional electronic valve coupled between said second end of said input transmission line and the common potential, a polarity of said unidirectional electronic valve opposing a polarity of said PIN diode such that a potential of the second end of said transmission line can not exceed a predetermined negative value.
