Power limiter/low-noise amplifier of C-band

The article describes designing of a low-noise amplifier with protection of input stages against influence input CW power to 2 W working in a range of frequencies 3...8 GHz with gain not less than 32 dB. The amplifier is made of the quasi-monolithic circuit. The basic stages of design, modeling of amplifier operation and its implementation are described. Comparative results of simulated and measured values of the developed amplifier are presented.
