  • Abstract
    This paper highlights some of the design choices made in maximising the sensitivity of the MeerKAT interferometer. In particular special care is taken in minimizing the system noise temperature in each component of the receiver front end. The receiver´s system noise temperature is below 7 K. The radiation patterns are stable over frequency with an antenna efficiency above 74 % and antenna noise temperature at zenith is below 11 K.
