Prospective designs of microwave power amplifiers for on-board equipment service systems are considered, in which the problem minimizing area occupied by them on a thermally stabilized plate spacecraft is solved. Microwave provide good heat dissipation and require degree redundancy. Each included redundant amplifier made boards located perpendicular to heat-stabilized fixed one or both sides. T...

The Axion Dark Matter eXperiment (ADMX) was designed to detect ultra-weakly interacting relic axion particles by searching for their conversion to microwave photons in a resonant cavity positioned in a strong magnetic field. Given the extremely low expected axion–photon conversion power we have designed, built and operated a microwave receiver based on a Superconducting QUantum Interference Dev...

We describe a novel oscillator that converts continuous light energy into stable and spectrally pure microwave signals. This light-induced microwave oscillator (LIMO) consists of a pump laser and a feedback circuit, including an intensity modulator, an optical fiber delay line, a photodetector, an amplifier, and a filter. We develop a quasilinear theory and obtain expressions for the threshold ...

High power, broad bandwidth, high linearity, and low noise are among the most important features in amplifier design. The broad-band spatial power-combining technique addresses all these issues by combining the output power of a large quantity of microwave monolithic integrated circuit (MMIC) amplifiers in a broad-band coaxial waveguide environment, while maintaining good linearity and improvin...

The reliability of electronic device is threatened in high power microwave (HPM) environment. In accordance with the situation that the emulation is ineffective in evaluating the accuracy and precision of the HPM effect to electronic device, the experimental method is used to resolve the problem. Low Noise Amplifier (LNA) and Limiter are selected as the objects for the experiments, the structur...

In this paper we present coplanar MMICs based on both, metamorphic (MHEMT) and pseudomorphic (PHEMT) high electron mobility transistor technologies. Starting with a modulator-driver MMIC for optical transmission systems, we describe state of the art MMICs like a 94 GHz low-noise amplifier, a 35 GHz and a 60 GHz medium power amplifier and finally we demonstrate the feasibility of a monolithicall...

We demonstrate experimentally a mechanism of the soliton generation in nonlinear active metamaterials. Our meta-structure consists of a ring resonator formed by a microwave amplifier loaded with a left-handed transmission line. We demonstrate a variety of nonlinear effects not described by weakly nonlinear models, and study experimentally the system’s spatiotemporal dynamics, including the gene...

This paper outlines a demonstration of a few remote and virtual laboratories at Labicom platform that were built with accordance to main IEEE P1876TM ideas. A few standardization approaches at above mentioned remote and virtual laboratories are briefly discussed. These laboratories were presented at interactive Labicom demo session during REV'16 conference and published in conference proceeding...
