Artificial Intelligence (AI) techniques are applied to develop a framework for the design and layout of MMIC circuits. This framework addresses key aspects of the design process, from circuit specification and initial design decisions through to final layout and preparation of the circuit for fabrication. A number of knowledge-based systems are incorporated into the framework to assist in speci...

We describe results from the initial operation of our coaxial gyroklystron experiment, which is being evaluated as a potential driver for future linear colliders. The interaction is designed to occur between a 500 kV, 500 700 A beam and a series of coaxial TE0n1 microwave cavities. Output powers in excess of 100 MW at 8.568 GHz are expected with an efficiency of about 40% [1]. We detail perform...

Intermodulation distortion (IMD) suppression is a critical issue in modern military and commercial RF/microwave systems. Pressed by the demands imposed by distortion-sensitive digital modulation formats, modern systems routinely specify linearity requirements that are impossible to attain using conventional approaches. To meet these new challenges, Marki Microwave has introduced the Two-Tone-Te...

This paper introduces a new approach to design low pass microwave filter using impulse invariant transform. In this approach, the analog specifications of desired low pass filter is transformed into the digital specification and then apply an optimization technique (DSP based) to get an approximate transfer function in digital domain. Further, the transfer function in continuous time domain is ...

The recent implementation of the fourth fundamental electric circuit element, the memristor, opened new vistas in many fields of engineering applications. In this paper, we explore several RF/microwave passive circuits that might benefit from the memristor salient characteristics. We consider a power divider, coupled resonator bandpass filters, and a low-reflection quasi-Gaussian lowpass filter...

According to WHO standard the RF leakage beyond +10 dBm are hazardous to human being. The microwave oven is a kitchen appliance which is used in day to day life. But, until 1967 an affordable and compact microwave oven was not readily available for domestic use. The obvious cooking advantages provided by the microwave oven ensured that its uptake would be rapid. It is extensive with up to 90 pe...

This series of articles discusses oscillator phase noise reduction techniques and gives specific resonant circuit solutions using lumped and distributed parameters for both frequency stabilization and phase noise reduction. These topics are covered in Part 1. Phase noise improvement can also be achieved by appropriate low-frequency loading and feedback circuitry optimization. The feedback syste...
