Abstract :
In this paper, we present an E-band MMIC low noise amplifier (LNA) using 0.1-μm GaAs pHEMT technology operating in 1V and 2V drain voltage. The E-band LNA shows small signal gain of 28 dB from 62 to 77 GHz with DC power consumption 44 mW. Noise measurement conducts in the package shows average noise figure about 4.5 dB from 75 to 90 GHz. The figure-of-merit (FOM) is 212.5 (GHz/mW), which is highest compared with other LNAs using 0.1-μm GaAs pHEMT technology.
