Abstract :
Two-stage monolithic microwave integrated circuit (MMIC) low-noise amplifiers (LNAs) have been fabricated using 0.15- mu m gate-length InP-based AlInAs/GaInAs high electron mobility transistors (HEMTs). The LNAs showed less than 1.2-dB noise figure and 21-22-dB gain over the 7-11-GHz band. These results are believed to be the best reported to date for a broadband MMIC amplifier at these frequencies. The authors describe the fabrication technology, the design procedure, and the experimental results.<>
