In this paper, we investigate the critical temperature dependence of the performance of niobium nitride superconducting hot electron bolometer (HEB) mixers. The input noise temperature and intermediate frequency (IF) noise bandwidth of superconducting HEB mixers of different critical temperatures $T_{c}$ (between 6 and 12 K) are simulated with a hot spot model. Simulation results show that the mixer...
In this paper, we present the design, fabrication and measurements of an ultra broad band amplifier with 92 GHz cut-off frequency intended for ETDM transmission applications over 40 Gbit/s. The circuit is based on InP double channel HEMT technology developed in OPTO+ to get high frequeny-breakdown voltage product. We will discuss the use of coplanar wave-guide lines and low impedance bias micro-strip...
