| Block | Function | Key Features | |-------|----------|--------------| | | Impedance transformation from 50 Ω to the optimal 0.5 Ω superconducting line | Broadband (0.5 – 30 GHz), tunable via MEMS varactors | | Superconducting Low‑Noise Amplifier (SLNA) | First‑stage amplification with noise figure < 0.2 dB | Four‑stage series‑cascade of Josephson parametric amplifiers (JPAs) | | Output Power Buffer (OPB) | Drives conventional 50 Ω loads while preserving linearity | Cryogenic HEMT buffer with 30 dB gain, 1 dB compression point at 12 dBm |
These specifications position the SCVD‑28014 as currently available for the X‑ and Ka‑band, while still offering a respectable output power that eases interfacing with room‑temperature RF chains. scdv-28014
A next‑generation “” version will integrate the cryocooler, magnetic shield, and RF interconnects into a monolithic module, reducing overall system volume by 30 % and simplifying field deployment. | Block | Function | Key Features |
