Abstract :
In this paper, we present an uncooled frontend of a receiver system for regular long-term ground-based observations of stratospheric and mesospheric ozone (and carbon monoxide). The frontend is intended for use in a total power radiometer, and is responsible for principal performance characteristics of the receiver (i.e. operating frequency, bandwidth and noise temperature).
