Abstract :
In this paper, we present the development and characterization of an H-band (220 - 325 GHz) low-noise amplifier MMIC, realized in metamorphic HEMT technology with a gate length of 35 nm. The active devices in the realized three-stage LNA are common-source and common-gate transistors connected in cascode configuration. The LNA circuit achieves a linear gain of 26.3 dB with a 3-dB-bandwidth from 218 to 260 GHz. The measured noise figure of the LNA is 6.1 dB in the frequency range around 243 GHz.
