Low-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 ...
متن کاملAdvanced Hemt Mmic Circuits for Millimeter- and Submillimeter-wave Power Sources
This paper focuses on InP-based, HEMT Monolithic Millimeter-wave Integrated Circuit (MMIC) power amplifiers for applications to heterodyne receivers, transmitters, and communications circuits. Recently, we have developed several HEMT MMIC circuits using HRL Laboratories' 0.1 um InP HEMT technology with unprecedented high frequency performance and output power. Our results include an 80 GHz band...

technology. They can be made on-chip along with an amplifier, mixer, multiplier, or other active circuit, or they can be printed separately on a ceramic substrate like alumina. The latter approach is usually most economical since real estate on III-V semiconductor wafers is costly compared to that of passive substrates, and they can easily be packaged alongside other MMICs and connected with bo...

متن کاملAdvanced MMIC Receiver for 94-GHz Band Passive Millimeter-Wave Imager
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 conve...
