- Abstract
- A wideband H-band detector operating near 300 GHz has been developed based on SiGe HBT technology. The detector consists of an on-chip antenna and a HBT differential pair for square-law detection. It showed responsivity of more than 1,700 V/W and noise equivalent power (NEP) smaller than 180 pW/Hz(0.5) for the measured frequency range of 250-350 GHz. The maximum responsivity and the minimum NEP were 5,155 V/W and 57 pW/Hz(0.5), respectively; both were obtained at 330 GHz with DC power dissipation at 9.1 W.
