Abstract :
In this paper, we present a K-band MMIC low noise amplifier (LNA) using 0.1-µm GaAs pseudomorphic high electron mobility transistor (pHEMT). The K-band LNA shows small signal gain of 29 dB from 18.5 to 30 GHz with dc power consumption 27 mW and demonstrates a measured noise figure of 2.1 dB from 20 to 33 GHz. The figure-of-merit (FOM) is 544 (GHz/mW).
