An experimental investigation of two low-noise amplifiers is carried out. The first amplifier contains one cascade on the HMC374 chip, the second LNA contains two cascades on the same chip. Amplitude and amplitude-frequency characteristics of both amplifiers are obtained, a comparison with the passport characteristics is made. The amplifiers correspond to the passport data for all parameters, except saturation power at the upper boundary frequency.

Keywords: Low-noise amplifier, amplitude-frequency response, amplitude characteristic, saturation power
