Design of high compression point josephson junction travelling wave parametric amplifiers for readout of millimetre and sub-millimetre astronomical receivers
Supra-THz heterodyne mixers generally have higher conversion loss compared to the millimetre-wave mixers. Hence, the overall receiver noise temperature becomes increasingly dominated by the first-stage semiconductor low noise amplifier (LNA), which still struggles to achieve quantum-limited noise pe...
