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.

This white paper presents some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.

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.

Demands upon satellite Telemetry, Tracking, and Control (TT&C) are increasing rapidly. New solutions are required to handle the anticipated increase of on-orbit traffic as well as the expanding data throughputs of space-borne infrastructure. This summary details some of the trends driving change along with technologies emerging to advance TT&C design.

• Electronic countermeasures (ECMs)
• How jamming, machine learning, and AI are changing the threat environment
• New ways to generate electronic attacks and evaluate your countermeasures’ response with intelligent adaptive advances in digital signal processing (DSP) and machine learning

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.

In this tech brief, ERZIA reviews the main technical points that make a COTS Microwave Modular Amplifier suitable for NewSpace missions, and takes a closer look at the changes or modifications that might be recommended, depending on the type of mission. ERZIA also includes a summary of their COTS used in NewSpace missions.

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.

This white paper describes the lifecycle of a modern mobile device, which includes identification of target requirements and goals, real-estate planning of components, design, prototype development, testing of the device at various stages, and commercial launch.

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.
