  • Abstract
    Using 0.25 micron gate-length High Electron Mobility Transistors (HEMTs), a two-stage amplifier has been developed that demonstrates the potential for high-gain, low-noise pre-amplification at K/sub a/ -band. The amplifier exhibits a noise figure of 4.0 dB with 16.5 dB gain at 37.5 GHz and under slightly different bias conditions shows flat gain of around 11.0 dB from 30.5-37.5 GHz.
