Abstract
A low noise superheterodyne receiver has been designed and constructed for the ground-based monitoring of stratospheric ozone. The receiver measures the ozone spectral line at 110.836 GHz. The low-noise front-end consists of a Schottky-mixer, a HEMT-amplifier at 3.6 GHz and a phase-locked Gunn-oscillator as LO and is followed by an acousto-optical dual spectrometer with 1.2 GHz bandwidth and 85 kHz resolution at the band center. A tunable passive cold load is used as a reference load.
