Build An E-pHEMT Low-Noise Amplifier (.PDF)
Although often associated with power amplifiers, E-pHEMT devices are also quite capable of supporting the design of efficient low-noise amplifiers.
Low-noise amplifiers (LNAs) for high-frequency applications have been based on GaAs metal-epitaxial-semiconductor field-effect-transistor (MESFET) and depletion-mode pseudomorphic-high-electron-mobility-transistor (pHEMT) technologies for some time...
