MTT-S International Microwave Symposium Digest.
Millimeter wave planar Schottky barrier mixer diodes with beam leads, low parasitic and one micron fingers have been developed for 35 GHz, 95 GHz and 140 GHz operation. Preliminary characterization of dual-finger mixer diodes has resulted in a double

A 94 GHz GaAs monolithic balanced mixer in a planar microstrip integrated circuit configuration has been demonstrated. A double sideband noise figure of 5.6 dB has been achieved at 94.5 GHz. This includes a 1.5 dB noise contribution of the IF preampl

The design and performance of a GaAs monolithic 180 degrees one-bit phase shifter test circuit for Ka-band operation is presented. Over the 27.5 to 30 GHz band the measured differential phase shift is within 10 degrees of the ideal characteristic and

The design and performance of GaAs monolithic 3-bit and 4/5 bit switched line phase shifters for Ka-band operation are discussed. Both conventional recessed and self-aligned gate (SAG) switching FET designs are presented. The insertionloss was as low

A circuit technique that employs a transformer wrapped around an active device to increase circuit density has been demonstrated with key building blocks for sensor systems. This technique is completely compatible with planar fabrication processes us

The authors have designed a novel thin-film edge emitter FEA (field emitter array) and report the first low-voltage field emission results from the thin-film edge emitter. The emitter is part of a thin-film diode structure which has a submicron spaci

The most successful Ring Laser Gyroscopes (RLGs) are gas-laser based. It has been recently shown that the type of anomalous dispersion associated with fast light, when present inside an RLG, can increase its scale factor. We evaluate several proposed
