Millimeter-Wave Diode-Grid Frequency Doubler

Abstruct-Monolithic diode grids have been fabricated on 2-cm square gallium-arsenide wafers in a proof-of-principle test of a quasi-optical varactor millimeter wave frequency multiplier array concept. An equivalent circuit model based on a transmission-line analysis of plane wave illumination was applied to predict the array performance. The doubler experiments were performed under far-field il...

High-power millimeter-wave rotary joint.

The rotary joint is a useful microwave component that connects a fixed part to a rotatable part. This study systematically analyzes the effect of the discontinuity on the interface of a rotary joint for several waveguide modes. Simulation results indicate that the transmission of the TE(01) mode is independent of the geometry of the joint, and thus is ideal for such application. A rotary joint ...

Final Report Project Name: Research on Novel High-power Microwave/millimeter Wave Sources and Report Documentation Page Research on Novel High-power Microwave/millimeter Wave Sources and Applications

Performance characteristics of a fundamental cyclotron harmonic, distributed-loss, TE01-mode gyrotron traveling-wave amplifier are studied theoretically. Absolute instabilities on both lower and higher order modes at the fundamental and second cyclotron harmonic frequencies present a severe limitation to the stable operating current and hence the device capability. General methods for stabilizi...

Low-Power Testing of Losses in Millimeter-Wave Transmission Lines for High-Power Applications.

We report the measurement of small losses in transmission line (TL) components intended for high-power millimeter-wave applications. Measurements were made using two different low-power techniques: a coherent technique using a vector network analyzer (VNA) and an incoherent technique using a radiometer. The measured loss in a 140 GHz 12.7 mm diameter TL system, consisting of 1.7 m of circular c...

Millimeter-wave FET modeling based on a frequency extrapolation approach

An empirical distributed model, based on electromagnetic analysis and standard S-parameter measurements up to microwave frequencies, is shown to be capable of accurate small-signal predictions up to the millimeter-wave range. The frequency-extrapolation approach takes advantage from a physicallyexpected, smooth behavior of suitably defined elementary active devices connected to a passive distri...
