Abstract :
A wideband image rejection mixer and a high real estate efficiency amplifier were designed and fabricated with a 0.25- mu m pseudomorphic high-electron-mobility-transistor (HEMT) process. The mixer, integrated on 0.6 mm/sup 2/, included an in-phase power splitter. It exhibited better than 30 dB of image rejection from 52 to 60 GHz with 14 dB of conversion loss including the power splitter. Combined with two 0.3-mm/sup 2/ IF monolithic amplifiers, the mixer exhibited 8 to 9 dB of conversion gain from 0.5 to 3 GHz. The amplifier, operating around 62-63 GHz, exhibited better than 8 dB/mm/sup 2/ gain density, with an input/output I/O voltage standing-wave ratio (VSWR) of 2.5.<>
