Strict electromagnetic regulations require verification of emissions compliance of all wireless products. As a result, harmonic measurement has become increasingly important especially as modern wireless communication systems strive to achieve an optimal balance between spectrum efficiency and DC power use.
There is something about a prize that helps get things done. Ever since the Longitude Prize was announced in 1714, organizations have used open competitions to encourage thinking outside the box. Unlike grants or contracts, competitions can be open to a broad spectrum of competitors, encouraging open exploration.

Picture one of the nation’s largest football stadiums packed with more than 100,000 people, each equipped with his or her own mobile phone. Wireless service providers typically rely on the stadium’s distributed antenna system (DAS) to maximize coverage inside of buildings. Unfortunately, the high-density of a stadium makes it challenging to service the simultaneous mobile connections while maintaining a high-quality signal. After each major event, it’s not uncommon for carriers to receive reports of performance issues that need optimization before the next game.
With the proliferation of smartphones, smartwatches and tablets in our society, instant and unhindered access to communication, information, entertainment has become an expectation in our daily lives. Emerging radio technologies will push download speeds into the Gigabit per second range and latencies into single-digit milliseconds, but supporting these capabilities ultimately leads to highly complex radio architectures. In order to address these market pressures, the MIPI RF Front-End Control Working group was formed to define a highly efficient but flexible control interface for RF front-end devices. MIPI-RFFE is an open standard being adopted industry wide to address current and future control and monitoring of modern wireless RF front-ends.
Engineers use the NI Vector Signal Transceiver to perform high-performance, reliable measurements using a software-defined approach that flexes to meet evolving requirements. Rapid adoption of this product family in wireless and semiconductor applications, combined with an increasing need to characterize products in production as well as in design, has led to an increased demand for harmonic measurement functionality and higher bandwidth among NI’s customer base.
Spectrum Defender® now supports NI's latest frequency range extender, the SignalCraft Technologies SC2250. Spectra Lab has partnered with SignalCraft to deliver an extended bandwidth product with a playback frequency range of up to 18 GHz. It fully integrates with all Spectrum Defender® platforms that utilize NI PXIe-5840 hardware. This upgrade is an innovative solution for design and test engineers.
SignalCraft Technologies (SCT) today announced the SC2250 – a signal conditioning module that extends the useful range of traditional 6 GHz RF instruments to microwave frequencies up to 18 GHz.
On June 19th, SignalCraft Technologies was pleased to host its annual Charity Barbeque. As a favorite social event of Calgary’s electronics industry for the past 15 years, it never fails to provide a much-needed opportunity for local electronics community to catch up on what’s happening in the industry while raising much-needed cash for a worthy cause. This year’s barbeque was a huge success with everyone’s generous contributions, we all managed to raise nearly over $2200 for a very deserving local charity.

In recent years, the electronics industry has experienced an explosion in the growth of embedded sensors being used in high-volume applications such as smartphones, wearables, automobiles, and the Internet of Things (IoT). This rapid growth is fueled by the development of a wide variety of small-sized, low-cost sensors being married to an ever-expanding array of innovative consumer applications. An excellent example is today’s typical smartphone, which incorporates 10 or more sensors measuring anything from light and biometric responses to motion and environmental conditions.
Every generation of mobile network brings about new technology and infrastructure improvements to support faster data rates, greater bandwidth, and improved efficiency and coverage. To keep up with these advancements, base station architectures have steadily evolved over time. The introduction of fourth generation cellular (4G) required major changes in the traditional analog radio architecture, such as the migration of all analog circuitry to the remote radio unit (RRU).
