An experimental study of two instances of low-noise amplifiers of the range 1.5-2.0 GHz is carried out. The following results were obtained: the amplification gain varies from 24 to 37 dB in the frequency range; the maximum output power was not less than 10 mW (10 dBm); the compression point of 1 dB is achieved with an input power of minus 16 dBm. To illustrate the measurement results, two amplitude-frequency characteristics and an amplitude characteristic of the second specimen are given. The main element of the studied amplifier is a chip of the type MAAL-007304.
