Abstract
A description is given of the design and performance of GaAs monolithic L -band amplifiers with low power consumption. One amplifier has been fabricated using a 1-μm depletion-mode (D-MESFET) process, and the other using 1-μm enhancement/depletion-mode (E/D) technology. Both the amplifiers have over 11-dB gain and a noise figure of 3 dB or less at 1 GHz. The power consumption of the D-MESFET amplifier is below 100 mW and that of the E/D amplifier is below 50 mW. Overall performance of the amplifiers is compared
