Advanced MMIC Receiver for 94-GHz Band Passive Millimeter-Wave Imager

چکیده
In this paper, we present the development of an advanced MMIC receiver for a 94-GHz band passive millimeter-wave (PMMW) imager. Our configuration is based on a Dicke receiver in order to reduce fluctuations in the detected voltage. By introducing an electronic switch in the MMIC, we achieved a high resolution millimeter-wave image in a shorter image collection time compared to that with a conventional mechanical chopper. We also developed an imaging array using MMIC receivers. key words: Dicke-radiometer, low noise amplifier, MMIC, passive millimeter-wave imager, SPDT switch

متن کاملA Low-Noise, High-Gain Quasi-Millimeter-Wave Receiver MMIC with a Very High Degree of Integration Using 3D-MMIC Technology
We present a highly integrated quasi-millimeter-wave receiver MMIC that integrates 22 circuits in a 3 × 2.3 mm area using threedimensional MMIC (3D-MMIC) technology. The MMIC achieves low noise (3 dB) and high gain (41 dB) at 26 GHz by using an on-chip image reject filter. It integrates a multiply-by-eight (X8) local oscillator (LO) chain with the IF frequency of the 2.4 GHz band and can use lo...

Advanced circuits based on metamorphic HEMT (MHEMT) technologies on 4” GaAs substrates for both millimeter-wave, and mixedsignal applications are presented. Extrinsic cut-off frequencies of ft = 293 GHz and fmax = 337 GHz were achieved for a 70 nm gate length metamorphic HEMT technology. The MMIC process obtains high yield on transistor and circuit level. Single-stage low-noise amplifiers demon...
متن کاملLow-loss Grounded Elevated Coplanar Wave- Guide for Sub-millimeter Wave Mmic Applica- Tions
A new type of elevated coplanar waveguide structure is described which uses airbridge technology to suspend CPW traces above a ground plane resting on a high permittivity substrate. The transmission line is effectively shielded from the substrate and is equivalent to conductor backed CPW with an extremely thin, air substrate. It is, therefore, insensitive to parasitic substrate effects such as ...
