In this work, the authors discuss the design of two low noise amplifiers (LNA) based on 1µm gate-length pHEMT InP transistors and using two different topologies. Designed for radio astronomy applications, the first is a cascode circuit with a maximum gain of 15dB and noise figure of 0.6dB, while the second is a 2-stage cascaded amplifier with 27 dB(More)
— In this work, the design of a novel low noise amplifier (LNA) based on 1μm gate-length InGaAs/InAlAs/InP pHEMT transistors is discussed. Designed for radio astronomy applications, this amplifier exploits a common drain configuration as an input stage and a common source inductive degeneration topology as an output stage. It exhibits a maximum gain of 30(More)
