In this paper, a low-power full-band low-noise amplifier (FB-LNA) for ultra-wideband applications is presented. The proposed FB-LNA uses a stagger-tuning technique to extend the full bandwidth from 3.1 to 10.6 GHz. A current-reused architecture is employed to decrease the power consumption. By using an input common-gate stage, the input resistance of 50 Ω can be obtained without an extra in... View full abstract»

In distributed oscillators, a large or infinite number of voltage and current variables that represent an oscillating electromagnetic wave are perturbed by distributed noise sources to result in phase noise.

Parametric amplification is a well-studied phenomenon by which a nonlinear reactance mixes an RF large-signal (pump) with an IF small-signal (source) to generate mixing products with gain. In this paper, two analytical models are derived and validated that predict limitations in the gain and efficiency of a parametric upconverter associated with varactor tuning range and quality factor.

Convergence is a well-known issue for standard space-mapping optimization algorithms. It is heavily dependent on the choice of coarse model, as well as the space-mapping transformations employed in the optimization process. One possible convergence safeguard is the trust region approach where a surrogate model is optimized in a restricted neighborhood of the current iteration point. In this paper,...

This paper presents a new type of varactor-tuned dual-mode bandpass filter. Since the two operating modes (i.e., the odd and even modes) in a dual-mode microstrip open-loop resonator do not couple to each other, the tuning of the passband frequency becomes simple with a single dc-bias circuit while keeping nearly constant absolute bandwidth. Design equations and procedures are derived, and two two... View full abstract»

## Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
