Titel
An active gate-pumped transconductance upconverter for terahertz frequencies
Abstract
A single-ended active frequency upconverter for H-band applications is presented. The mixer is designed for a LO frequency at 300 GHz and shows a flat conversion gain curve over a large bandwidth from 270 to 313 GHz with a conversion loss of 7 dB at a very low LO input power of -3 dBm. In saturation a simulated gain of almost 1 dB is reached. The MMIC was realized in a 35nm gate-length InGaAs-based metamorphic HEMT technology.
