Abstract
The paper presents the experimental results of an investigation into a low-noise non-cooled amplification module consisting of the parametric amplifier and the quasi-optical pumping oscillator, intended for implementation as an input circuit of the 60 GHz wave band receivers. The coaxial waveguide resonator was used as an idler frequency loop of the parametric amplifier, while the quasi-optical sphere-corner-echelette open resonator was used as the same for the oscillatory circuit of the pumping oscillator. The experimental results for the model of amplification module, which is executed using the unpacked Schottky-barrier diode and IMPATT diode, are provided. The gain is no less than 16 dB within the 1 GHz bandwidth and the noise temperature is no more than 550 K.
