This paper presents the design and characterization of W-band IQ sub-harmonic MMIC mixers based on the UMS BES Schottky diode process. The mixers were characterized at 300 K and 20 K physical temperature. They are a key component for the compact heterodyne multi-chip modules to be used in the 16-element Argus focal plane array, which will be deployed at the Green Bank Telescope in late 2014. The RF...
In this paper, we demonstrate non-destructive cryogenic probing of monolithic microwave integrated circuit (MMIC) amplifiers at W-band and discuss the implications for the development of large-format focal plane arrays for radio astronomy. Using a purpose-built cryogenic probe station to measure S-parameters and noise temperature of MMIC low-noise amplifiers (LNAs), an order of magnitude increase...

In this paper, we describe two monolithic millimeter-wave integrated circuit (MMIC) low noise amplifiers (LNAs) for W-Band which have a noise temperature of 30K or better over a wide bandwidth when cryogenically cooled. The LNAs were designed and fabricated in NGC's InP HEMT MMIC process having 35 nm gate length and employing an InAs Composite Channel (IACC). A two-stage amplifier exhibits room temperature...
