Abstract
We have developed V-Band (50–75 GHz) monolithic millimeter-wave integrated circuit (MMIC) low noise amplifiers using NGC's 35 nm InP HEMT technology. The MMIC LNAs exhibit noise temperatures of 150–270K over the full waveguide band. Subharmonic MMIC mixers were also developed using United Monolithic Semiconductor's GaAs Schottky diode process, and cover V-band with 15–21 dB conversion loss. These components form the front end of receivers that could be used for radio astronomy. While much of V-Band is opaque to the atmosphere, a future space probe to map the intensity of carbon monoxide (CO) in V-band would help astronomers understand the early universe.
