RECEIVING MODULE OF SOLID MICROWAVE BRIDGE FOR PULSE ELECTRONIC PARAMETRIC RESONANCE COHERENT SPECTROMETER OF 8 MILLIMETER RANGE

摘要

A receiving module of solid microwave bridge for pulse coherent spectrometer of electron paramagnetic resonance range comprises an attenuator, low-noise amplifier protected against pulse signals by a limiter and a switch, a balance mixer and a video amplifier. In addition, at the low-noise amplifier output a second balance mixer having phase shift for 90° relative to the first mixer is installed, as an amplifier two-channel video-amplifier is installed.
