Abstract

We report on design and performance of a low‐power‐consuming two‐stage MMIC LNA using AlGaAs/GaAs pseudomorphic HEMTs with 0.25‐μm T‐gates. The MMIC LNA showing a noise figure of 2.55 dB with 17‐dB associated gain at 5.8 GHz consumes only 18 mW, which is the lowest value of power consumption ever reported to date from PHEMT MMIC LNAs around this frequency range, and is attributed to the optimization of the gate width and current, as well as the use of a circuit with a single current path. © 2005 Wiley Periodicals, Inc.
