Abstract: A frequency- and bandwidth-tunable filter based on dual-mode movable microstrip-cavity structure is proposed in this letter. The TE101 and TE011 modes of the cavity are employed as the ...

Abstract: An analog-to-digital converter (ADC) with broad bandwidth and high dynamic range is of the utmost importance for modern radio frequency (RF) applications. However, as the bandwidth increases ...

This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

Graduate student Hossein Jalili displays the millimeter-wave/terahertz phased array chip that he and Assistant Professor Omeed Momeni prototyped in the UC Davis Millimeter-Wave Research Center in the ...

You have surely read about signal bandwidth in various technical literature, but exactly what is it and why does it matter in signal processing projects? All circuits and transmission paths limit the ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK ...

Radar waveforms are classified into three categories based on the bandwidth of operation. With multiple waveforms available for use, such as FMCW and pulse-modulated, it’s imperative to decide on the ...
