Back in 2019, Google made waves by claiming it had achieved what has been called “quantum supremacy”—the ability of a quantum computer to perform operations that would take a wildly impractical amount ...

Low phase noise oscillators are critical components in modern communication, sensing and radar systems, where extreme frequency stability is paramount. These oscillators offer superior performance by ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

As the number of higher-throughput applications grows, so does the need for a wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Oven-controlled crystal oscillators (OCXOs) developed by NEL Frequency Controls deliver ultra-low phase noise in a dual-frequency reference model (DFRM). The O-CDFXYZXX-X-X-10MHz/100MHz DRFM consists ...

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for automotive radar sensors at 80 GHz using the interferometric measurement approach in ...

Coherent laser ranging systems confront a fundamental trade-off: higher resolution typically comes with increased system complexity and cost. Researchers from Tsinghua University have demonstrated a ...

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

Noise has always been important to communications experts, but it’s quickly becoming an issue that every semiconductor designer has to contend with. Some chips already have been compromised. Noise can ...
