Stop the Clock, How Advances in Quartz Crystals and Silicon Germanium BiCMOS Circuits Simplify High Speed Clock Generation for RF Data Converters

As the demand for higher frequencies and data rates and more accurate measurement capabilities increase, achieving ultra-low clock jitter for ADC and DAC converters becomes a critical specification. This paper illustrates how a high-quality crystal oscillator paired with a high-performance PLL/VCO enables small form factor, high-performance <30 fs clocks.

Output Power Measurement on Noise Sources

Noise sources used for noise figure and gain measurements are typically controlled by the spectrum analyzer or noise figure meter instruments and are calibrated with their ENR value (Excess noise ratio). This application note describes a technique to perform a calibrated noise power measurement (P_hot) with spectrum analyzers and noise sources.

How to Select Antenna Front-End Components for Non-GEO Space Applications

The adoption of active electronically scanned antennas (AESAs) for satellite communication (satcom) has offered greater flexibility for operators and consumers. This article will review the design considerations when choosing antenna frontend (FE) components (low noise amplifiers and power amplifiers) for use in these beamforming arrays. 

Effective Test Strategies for DoD’s 5G Rollout

The DoD is adapting commercial 5G technology to meet tactical communications needs in terrestrial and non-terrestrial networks. This paper covers current 5G technologies and standards, demonstrates the importance of testing throughout the development process and offers a comparison of different use cases and test solutions.

ONYX Oscillators in Low Earth Orbit

As access to and utilization of the low Earth orbit (LEO) region has expanded, so too has demand increased for affordable, mass producible space-worthy timing devices. In this white paper, Quantic Wenzel outlines the approach, process, and results of adapting and qualifying an established family of ONYX oscillators to production for commercial LEO space applications.

K-Band Microwave DACs Driving Quantum Computing Technologies

As classical computer developments asymptotically approach fundamental computational speed limits, quantum computing has the potential to be hundreds of millions of times faster, at a fraction of equivalent development costs. This will occur only if quantum computer designers can ensure microwave signal-source Qubit drive capability that is accurate, synchronized, reliable, and consistent.
