Time Difference of Arrival (TDOA)

Time Difference of Arrival (TDOA) is a technique for geo-locating RF sources. It requires three or more remote receivers (probes) capable of detecting the signal of interest. Each probe is synchronized in time to capture corresponding I/Q data blocks. Software shifts the time signature of each I/Q data set to find the difference in the arrival time at each probe.

Design Secrets Behind the World’s First K-band DAC

This paper covers design choices of the world’s first K-band data converter. By avoiding established CMOS design principles and applying an ultra-high speed process, new capabilities emerged; a compact, single-core quantizer and design expertise led to breakthrough performance and layout and circuit simplifications are dominant design considerations.

Radar Cross Section of Aircraft with Engine Inlets

At radar frequencies, 1GHz and above, asymptotic methods are usually preferred to calculate the radar cross section (RCS) of targets like aircraft, since the main parts of the target are more than an order of magnitude larger than the wavelength. The challenge is how to combine these methods to compute the RCS. In this white paper the two-step method that obtains accurate results in limited time is detailed.

Business Considerations of Equipment Refresh in a Calibration Laboratory

Every leading-edge technology has to be measured using test equipment that goes even farther. While this has tremendous implications for calibration labs, the upside of upgrading often offsets the costs. Business Considerations of Equipment Refresh in a Calibration Laboratory identifies the factors that provide the biggest benefits.

Eliminate Risk with Proper Calibration

In this technical white paper, read how to control the costs of test and ownership of your highly valued test and measurement assets. We offer an in-depth view of maintenance and calibration and offer tips to help you adopt technology faster and lower your cost of test.

Passive Radar Receiver Using FMC-1000

In 2015 Entegra Solutions were contacted by Thales Air Traffic Management looking for the highest dynamic range, wide bandwidth data acquisiion card available. Their objective was to build a passive radar using beamforming techniquest to receive reflections of DVB-T Tv signals from aircraft to replace traditional airfield radars.

Examining the Challenges in Implementing and Testing Massive MIMO for 5G

In 5G, the use of massive MIMO is a revolutionary idea. It has major implications for development and implementation within the 5G ecosystem. It also affects the set of tools you'll need to characterize and validate these highly complex systems.

Fundamentals of Building a Test System: System Maintenance

In a perfect world, systems would never fail. Unfortunately, this is not reality—at least not yet. Systems fail and sudden, unexpected failures can be costly. Although you cannot completely remove the risk of failure, even with the most well-thought-out plans, you can reduce it. Ensure you have a maintenance strategy that can help you manage cost if something does go wrong and reduce the risk of failure.

Cable Harness EMC/EMI

Bundles of electrical cables in vehicles, aircraft, ships and buildings pose electromagnetic compatibility and interference challenges to the electrical design engineer. Due to their lengths, they are more likely to radiate or pick up irradiation than many other electrical components and systems. This white paper will discuss how these challenges can be met with the aid of electromagnetic simulation.

5G in Perspective - A Pragmatic Guide to What's Next

This paper examines the current state of LTE networks and the ways it could evolve to deliver a gigabit-per-second user experience. To accomplish this, the ecosystem will need to deliver 100x data throughput improvement. As a premier provider of RF front-end solutions, Skyworks believes we have the capability to enable this evolution using tools and techniques provided in the LTE specification leading up to the release of 5G. Additionally, this paper explores the impact of new 5G services from the mobile and fixed wireless perspective.
