Circuit theory for spatially distributed microwave circuits

IEEE Transactions on Microwave Theory and Techniques, 1998
A spatially distributed radio-frequency (RF) circuit, microwave, or millimeter-wave circuit does not have a global reference node as required in conventional nodal analysis. Instead, local reference nodes associated with ports are required. This paper adapts modified nodal analysis to accommodate spatially distributed circuits, allowing conventional ...

Application of TLM to Microwave Circuits [PDF]

, 2000
The design of microwave circuits has traditionally been based on lumped circuit concepts. As an example, the design a high-pass microwave filter starts with the design of a low-pass prototype with a Chebyshev response which has the required return and insertion loss.

Superconducting Linear Microwave Circuits

18th European Microwave Conference, 1988, 1988
Applications of superconductivity in microwave technique make possible to develop a) high quality resonators, filters delay lines with small losses and controlled dispersion, b) modulators, switches on the basis of S-N transition (the transition from superconducting to normal state of material under the influence of transport current, laser light etc.,

Monolithic microwave integrated circuits

2000
Publisher Summary Monolithic microwave integrated circuits (MMICs) and similar devices are used in a wide variety of receivers. These devices may be very wideband or relatively narrowband. Very wideband amplifiers have a bandpass (frequency response) of several hundred megahertz or more, typically ranging from sub-VLF to the low end of the microwave ...
