Wearable device designers targeting consumer goods, fitness or medical applications have numerous antenna challenges which impact the connected effectiveness of their device. Issues such as harsh or rapidly changing electrical antenna environments, diverse networks, and small form factors are just a few of the design dilemmas. Tunable RF capacitors such as the WS1040 tackle these issues by enabling real-time control and adaption to the electrical signal environment. In addition, the WS1040 allows an electrically small and physically thin antenna used in a wearable device to tune over a wide frequency range, enabling OEMs to expand their product lines into global markets.

In addition to wearable applications, the WS1040 is well suited for traditional mobile antenna applications such as smartphones. For the RF network designer, the WiSpry WS1040 offers tremendous flexibility that goes beyond antenna tuning. By providing four independently addressable, tunable, highly accurate RF capacitors, the product is also ideal for phase shifters, PLLs, and power amplifier matching.

“Mobile wearable devices are exciting applications - with numerous design challenges which ultimately impact their effectiveness and market acceptance,” said Jeff Hilbert, president and founder of WiSpry, Inc. “The ultra-compact, low power, high performance WS1040 solves many of the antenna issues associated with wearable device design. WiSpry’s Tunable RF leadership is evident in this product, and is one of many new Tunable RF products scheduled for release in the coming months.”

WS1040 Technical Features and Benefits

  • 12 pf of total capacitance with each capacitor individually tunable
  • Configurable in a series or shunt mode with individual pin-out for each capacitor
  • MEMS-based technology delivers ultra-low harmonics and intermodulation
  • Dual hardware configurable USIDs avoids addressing conflicts
  • Integrated DC/DC converter enables operation with one single supply rail
  • ADS simulation models available for easier, more accurate designs

In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
Docker containers have brought great opportunities to shorten the deployment process through continuous integration and the delivery of applications and microservices. This applies equally to enterprise data centers as well as the cloud. In his session at 20th Cloud Expo, Jari Kolehmainen, founder and CTO of Kontena, discussed solutions and benefits of a deeply integrated deployment pipeline using technologies such as container management platforms, Docker containers, and the drone.io Cl tool.

Any startup has to have a clear go –to-market strategy from the beginning. Similarly, any data science project has to have a go to production strategy from its first days, so it could go beyond proof-of-concept. Machine learning and artificial intelligence in production would result in hundreds of training pipelines and machine learning models that are continuously revised by teams of data scientists and seamlessly connected with web applications for tenants and users.
Given the popularity of the containers, further investment in the telco/cable industry is needed to transition existing VM-based solutions to containerized cloud native deployments. The networking architecture of the solution isolates the network traffic into different network planes (e.g., management, control, and media). This naturally makes support for multiple interfaces in container orchestration engines an indispensable requirement.
