WiSpry Delivers High Performance Antenna Tuning With Quad Capacitor Single Chip Implementation

WS1040 Enables Smartphone and Wearable Applications Requiring Small Form Factor, Low Power and Better Connectivity 

WiSpry, Inc., the leader in high-performance tunable radio frequency (RF) semiconductor products for the wireless industry, recently announced the WS1040 tunable RF quad capacitor array, enhanced for challenging applications such as wearable mobile devices. The WS1040 single chip delivers the highest performance and the industry’s highest Q in an ultra-compact package that is 30% smaller than WiSpry’s class-leading W1050 solution. Support for multiple USIDs and system configuration flexibility in shunt or series mode enables maximum circuit design flexibility. For more technical information, visit http://www.wispry.com

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.”
