Abstract :
We present results of packaged mm-wave receiver components based on 100nm mHEMT technology. The components are to be used for observations of the atmospheric lines at 118 GHz and 183 GHz. A 90-130 GHz single-chip receiver MMIC, including LNA, mixer and LO multiplier chain, is packaged in to a waveguide block, characterized and compared to on-wafer measurements. A breakout LNA circuit is also packaged and its performance is compared to the receiver. A 183 GHz source is designed to be used as a LO source.
