MMIC transmission lines for multi-layered MMICs
1991 IEEE MTT-S International Microwave Symposium Digest, 2002Multilayered MMIC (monolithic microwave integrated circuit) transmission line configurations are proposed, and their performance is experimentally investigated. Four transmission line structures have been fabricated using polyimide films: (1) microstrip line with overlay, (2) inverted microstrip line, (3) trapezoid microstrip line, and (4) valley ...

Uniplanar MMIC Hybrids--A Proposed New MMIC Structure
IEEE Transactions on Microwave Theory and Techniques, 1987A new "uniplanar" circuit configuration for monolithic microwave integrated circuits (MMIC's) has been proposed. It uses a combination of coplanar waveguides and slotlines on one side of the substrate. The key components for the uniplanar structure are air bridges, which provide T junctions and transitions from coplanar waveguides to slotlines or vice ...

This paper describes the design and implementation of a new class of fully integrated oscillators in standard MMIC technology. Each oscillator comprises of a rectangular waveguide cavity resonator, a loop amplifier, and a phase shifter. Several cavities are constructed on standards GaAs substrate with quality factors of 120-170 between 40-50 GHz.
