摘要: For passive mm-wave imaging applications, broadband receivers functioning within atmospheric windows are highly desired. Within this paper, a heterodyne receiver chipset utilizing the 140 GHz window is presented. The based on two different millimeter-wave monolithic integrated circuits (MIMICs). One MIMIC including low-noise amplifier, down-conversion mixer, frequency multiplier and local oscillator buffer amplifier together with distribution network. other voltage-controlled (VCO) working in 35 range to generate signal for (down-converter) chip. process technology chosen realize 100 nm gatelength metamorphic InAlAs/InGaAs high electron mobility transistor (HEMT) 50 μm thick 4 inch diameter GaAs substrates. chips grounded coplanar waveguide (GCPW) technology. an operation band from 120 145 GHz, demonstrates flat conversion gain between -1 +2 dB power consumption of mW. VCO tuneable 31 37 associated output levels -2 +1 dBm. Detailed descriptions individual building blocks given measured results presented as well receiver.
