Abstract

A set of broadband low noise interference-immune amplifier modules comprising matched broadband amplifiers and matched filters is described. In the frequency band 1-100 MHz these devices ensure a low noise figure, high dynamic range, matching in a wide frequency band, stability, identity of parameters, versatility, and high compatibility of stationary and mobile systems. Connection of modules makes it possible to implement a complicated amplifier system with the specified amplitude-frequency response and low level of amplitude and phase errors. The parameters and characteristics of modules, their design features and principles are given. The amplification system of the largest UTR-2 decameter band radiotelescope is described
