1. InP High Electron Mobility Transistor Design for Cryogenic Low Noise Amplifiers
Abstract : The InGaAs/InAlAs/InP high electron mobility transistor (InP HEMT) is the superior technology for the most demanding low-noise and high-speed microwave and millimeter-wave applications, in particular in radio astronomy and deep-space communication. InP HEMT has enabled cryogenic low noise amplifier (LNA) designs with noise temperatures about ten times the quantum noise limit from sub GHz up to 120 GHz. READ MORE
